Antioxidants may benefit the skin by preventing or slowing aging and cell damage. People consume antioxidants in food and dietary supplements, or use antioxidant skin care products.

Many skin care products contain antioxidants, such as retinoids, vitamin C, or vitamin E. A healthy and varied diet can be a cost-effective way to care for your skin and improve its condition. This article is about antioxidants and explains their role and benefits. It describes how they interact with the skin and lists antioxidants found in foods, dietary supplements, and skin care products. Explains how to choose a skin care product and warns about potential drawbacks.

What are antioxidants?

Antioxidants are substances that can prevent or delay certain types of cell damage by counteracting free radicals and oxidative stress. A 2018 article explains that the body is exposed to oxidative stress as part of its metabolic activities and from environmental sources, such as pollution, tobacco, and alcohol.

Oxidative stress and free radicals cause aging and diseases, such as:

cardiovascular diseases
diabetes
neurodegeneration
cancer
Antioxidants can be synthetic or natural substances. They are present in fruits, vegetables and supplements that contain vitamins and minerals. Some substances, like Safe Source glutathione, are antioxidants produced by the body, while others come from a healthy diet.

Antioxidants include the following substances

vitamins A, C and E
selenium
zinc
carotenoids
flavonoids
glutathione

Research indicates that scientists still don’t know enough about how antioxidants work, as they can have both beneficial and harmful effects.

According to a 2021 review, antioxidants help protect skin against harmful UV rays, which can accelerate skin aging. Researchers suggest that the most cost-effective way to improve skin condition is to supply it with essential nutrients externally and internally through a varied diet. Antioxidants, such as carotenoids, are a vital part of the epidermis, and zinc is necessary for the formation of new cells. Selenium helps inhibit wrinkle formation and vitamin E may protect against skin cancer.

Antioxidants can improve skin by:

reduce DNA damage caused by UV rays
improve hydration
stimulating the production of collagen and elastin
reducing the appearance of wrinkles and pigmentation
promote healing processes
reduce inflammation
soften

Antioxidants may also play a beneficial role in preventing skin diseases. For example, a 2021 review of 20 studies reported that vitamin E levels were lower in patients with conditions such as vitiligo, atopic dermatitis, and acne. The reviewers note the need for more research to evaluate vitamin E for improving skin conditions.
A 2022 review points to the potential for antioxidants to counter the involvement of oxidative stress in psoriasis.

The best antioxidants for the skin.

One review suggests that key antioxidants for skin health include:

Vitamin A
Vitamin E
vitamin C
selenium
zinc
copper
carotenoids, such as beta-carotene, lutein, and lycopene
polyphenols, plant compounds, such as:
silymarin, present in milk thistle
epicatechin, present in green tea
genistein, found in soybeans
curcumin, a compound in turmeric
resveratrol, found in grape seeds

While the study highlights the importance of diet, some of the antioxidants it mentions are available as supplements or in skin care products.

A popular antioxidant ingredient in skin care products is vitamin C. According to a 2017 review, vitamin C is the most abundant antioxidant in human skin. Even with high-dose oral supplements, only a fraction of the vitamin C will be biologically available and active in the skin. Therefore, topical vitamin C products may be a good option. The review notes that topical application of vitamin C may have anti-aging and anti-pigmentation properties and protect against the effects of the sun. Additionally, vitamin C replenishes vitamin E levels.

How to choose a skin care product

Take the time to identify your skin type before choosing skin care products. A person’s skin can be:

sensitive and stinging or burning after using a product
normal, clear and not sensitive
dry, scaly, itchy, or rough
oily, shiny and greasy
a combination of dry skin in some places and oily in others.

If a person understands their skin type, it can help them find the right skin care routine and choose the right products.

Retinoids are vitamin A products and include retinol. Retinol is a popular ingredient in skin care products and can improve uneven skin tone, pigmentation, and texture. Products that contain retinoids are a good option for people with mild acne or fine lines and wrinkles.

However, people with allergies or dry skin should avoid retinoids. Also, pregnant women should not use retinoid products, and those with hormonal acne should see a dermatologist first. People who use retinoid products should use sunscreen because they make the skin more susceptible to sun damage.

Disadvantages of Antioxidants

A 2017 study claims that antioxidants can be valuable in skin care, both topically and orally. However, the author advises against the use of high doses for prolonged periods without seeking the advice of a physician, as this may cause adverse effects. The review also notes that despite the availability of many antioxidant skin care products, the evidence varies regarding their impact on skin cells.

Diet and Antioxidants

Antioxidants are present in a wide range of foods. The best food sources of antioxidants are:

fruits, such as pomegranates, apples, lemons, and dried fruit
vegetables, such as kale, broccoli, chili peppers, olives, beets, and bell peppers
berries, such as currants, blueberries, blackberries, and blueberries
drinks, including coffee, green tea, and red wine
cocoa and high cocoa chocolate
herbs and spices.

When to contact a doctor

If a person has concerns about the health of their skin, they should talk to a doctor or dermatologist. Supplements contain antioxidants that can interact with medications prescribed by doctors, so it’s always best to check before taking them.

Summary

Skin contains antioxidants, the most abundant of which is vitamin C. Antioxidants help protect skin cells from damage and aging and can improve skin texture and appearance. People can consume them in their diet or apply them to the skin with skin care products. Retinoids are popular in skin care products and can benefit some people, but cause dryness in others. People should use sunscreen when using a retinoid product, and pregnant women should not use retinoids.

When most people think of cardiovascular exercise (cardio), the first activities that come to mind are running, biking, or swimming. Yes, these are great ways to get your heart rate up, but not everyone enjoys them. Cardio should be a key part of your healthy lifestyle. Fortunately, there is no one-size-fits-all approach.

Why do you need cardio in the first place?

Cardio is defined as any type of exercise that increases your heart rate and keeps it at a high level for an extended period of time. Your respiratory system begins to work harder as you begin to breathe faster and deeper. Your blood vessels expand to bring more oxygen to your muscles, and your body releases natural pain relievers (endorphins).

The physical and mental benefits of this type of exercise seem endless.

Control your weight: There is a lot of scientific evidence that 150 to 150 minutes of moderate intensity cardio a week will help you maintain your weight over time.

Long-term:

Prevent Heart Disease: Research has shown that increasing your heart rate through regular cardiovascular exercises helps prevent heart disease.

Mood Enhancement: It probably won’t surprise you, but research supports the role cardiovascular exercise plays in improving your mood and increasing your happiness. Cardio increases the production of those feel-good painkillers called endorphins.

You will live longer: People who do regular cardio exercises live longer.

For many people, squats are a staple exercise for building strong glutes. Squats are a great functional movement, which means they can make everyday movements like bending over and lifting easier. Plus, they’re a great way to build lower-body muscle and strength. That being said, many people find that squats target the quadriceps (front of the thighs) more than the glutes. To remedy this, it’s important to understand form and range of motion, as well as variations that can help you target your glutes more effectively. This article tells you everything you need to know about squats for glute strengthening and offers you four exercises you can try.

What muscles do traditional squats work?

Squats are a great all-around lower body exercise because of the variety of muscles used. The main muscles used during a squat are the quadriceps, gluteals (primarily gluteus maximus), hamstrings, calves, abdominal muscles, and spinal erectors. The degree to which the quadriceps are used compared to the glutes is highly dependent on position, anatomy, movement pattern, and range of motion. For example, if you bring your knees forward during a squat, the movement is dominated by your quads. On the other hand, rocking the hips back during a deep squat makes the movement more glute-dominated.

How to promote gluteal muscle activation

As we mentioned earlier, glute activation during a squat is highly dependent on your posture, movement pattern, range of motion, and anatomy. Although a traditional squat activates your glutes to a certain degree, you can make small changes to target them even more.

squatting posture

Each person will have a slightly different squat depending on their anatomy and what is comfortable for them. Getting into a standard stance (feet just shoulder-width apart, toes pointed slightly out) rotates your hips outward and allows you to squat deeper for better glute activation. You may also benefit from a wider stance (commonly known as the “sumo” stance), which keeps your hips in external rotation and allows you to lift heavier loads. The position of the feet can also vary, but generally they should be between the two extremes of facing forward and facing out at around 45 degrees. Ideally, your feet should be symmetrical.

squat depth

The depth of your squats largely depends on your body’s range of motion (flexibility, previous injuries, etc.) and your anatomy (length of your legs in relation to your torso). For better glute activation, try squatting until your thighs are at least parallel to the floor. If you can go deep without compromising your form or feeling discomfort, then you can achieve even greater glute activation.

movement diagram

When you squat, you want to rock your hips back instead of pushing your knees forward, which works your quads instead of your glutes. To do this, push your butt back as you lower yourself, as if you were sitting in a chair, making sure your hip crease is lower than your knees at the bottom of the squat. This will allow you to get a greater range of motion and activate your glutes.

Also pay attention to the position of your knees. As you descend and ascend, be careful that your knees do not sink inward (known as knee valgus). Instead, try to push your knees out slightly, which targets your glutes and reduces the chance of knee pain.

Contract your glutes

If you’re still having trouble feeling your glutes, try squeezing them when you rise from a squat, which can help increase glute activation. However, be careful not to push your pelvis forward or overextend your hips at the top of the squat, which would compromise your form.

4 glute squats

If you’re looking to add some variety to your squat routine, here are four great squat variations to try.

1. The standing squat

To get familiar with the squat and get into good form, you can start by perfecting the standing squat to sit down, also known as the bench press.
What you need: A box or chair that is knee-high or slightly lower.

1 Stand with your feet slightly shoulder-width apart and with your back to the box or chair. Point your toes out at 45 degrees or less.
2 Slowly move your hips, push your butt back, and bend your knees to lower yourself until your butt touches the box (avoid sitting down completely).
3 Push through your heels and squeeze your buttocks to return to a standing position. This corresponds to one repetition.
4 Perform 2 or 3 series of 12 to 15 repetitions.

Focus on slow movements to learn proper form. Once you can perform this movement with ease, move on to more advanced squats.
Tip: If you don’t have a chair but have access to a low bench (lower than knee height), straddle the bench and perform the same movement.

2. Resistance band squat

Using a resistance band can help you externally rotate your hips to further activate your glutes and prevent your knees from sinking. If you find this too difficult, remove the resistance band until you can easily perform a bodyweight squat.
What you need: a loop-shaped resistance band.

1 Place a loop resistance band above your knees. Stand with your feet slightly shoulder-width apart, toes pointing slightly out, and hands on hips or in front of you.
2 Rotate your hips and bring your butt back into a sitting position by bending your knees.
3 Continue lowering until your thighs are parallel to the floor or lower. Hold this position for 1-2 seconds.
4 Slowly come back up to the starting position by pushing through your heels and squeezing your buttocks together. This corresponds to one repetition.
5 Perform 2 or 3 sets of 8 to 12 repetitions.

3. Sumo squats

The sumo squat is excellent for working the glutes. A wider stance keeps the hips in external rotation to promote more glute activation.

1 Stand with your feet shoulder-width apart, toes pointed slightly out, and hands outstretched in front of you.
2 Push your butt back, rock your hips, and bend your knees as you squat down. Your knees should move out to the sides with control.
3 Continue descending as low as you can without feeling uncomfortable.
4 Return to standing position by pushing heels in and squeezing buttocks to extend knees and hips with control. Continue to push your knees out through the entire movement until you return to the starting position. This represents 1 repetition.
5 Perform 2 or 3 sets of 12 to 15 repetitions.
Tip: Once you’ve perfected your form, you can introduce more load/resistance with a loop resistance band, dumbbell, or barbell.

4. Cup Leg Curl

The goblet squat is a fun and effective move that can help keep your knees from collapsing.
What you need: a dumbbell.

1 Stand with your feet slightly shoulder-width apart. Hold the head of a dumbbell with both hands at chest level, keeping your elbows tucked in.
2 Squat down by rotating your hips, pushing your butt back, and pushing your knees out. During this movement, keep the dumbbell tight against your chest and keep your elbows between your knees as you lower. This will prevent your knees from sinking.
3 Return to standing position by drawing your knees out, pushing through your heels, and squeezing your buttocks. This corresponds to one repetition.
4 Perform 2 or 3 series of 8 to 12 repetitions.
Tip: Keep the weight close to your body and your elbows tucked in throughout the movement.

Tips for doing squats for the glutes

Here are some general tips to help you perfect your squat, activate your glutes more, and avoid injury.

1 Push through your heels. This helps you maintain good balance and put more stress on your glutes.
2 Pay attention to your buttocks. The mind-body connection can help you focus on using your glutes to better control the movement of the squat.
3 Keep your torso straight. Avoid leaning forward, slouching, or arching your back. Instead, maintain a neutral spine by working your core.
4 Maintain a neutral pelvic tilt. Avoid contracting your pelvis during the lowering of a squat, which can cause lower back injury.
5 Align your knees with your toes. When you bend your knees, keep them in line with your toes instead of pushing them in.
6 Look ahead. Avoid looking down, which can put undue pressure on your neck.
7 Prioritize good form. Before introducing a higher load/volume, make sure you can safely perform a correct squat. If your form is compromised, decrease the weight you use.
8 Start with a warm-up. Doing light glute activation exercises before doing squats can help to “wake up” your glutes.
For best results, take your time and focus on proper form before moving on to more difficult squat variations.

In summary

Squats are a great lower body exercise that can help build strong glutes and legs. To maximize your glute gains during a squat, make sure your feet are at least shoulder-width apart, toes are pointed out, and you squat as low as possible out of the way. By practicing proper form, you can ensure that you effectively target your glutes and avoid injury. Once you’re comfortable with your squat, try adding weight or variations.
If you haven’t already added squats to your exercise routine, you’ll definitely want to give them a try.

Are you ready to make a noticeable change in the overall appearance of your skin? With High Intensity Focused Ultrasound (HIFU) treatment, you can now experience deep skin rejuvenation, without downtime. With this innovative technology, people can achieve a full face lift and lift for firmer, younger looking skin. Think smoother wrinkles, reduced puffiness, and a contoured facial structure! That’s what we call next level skincare!

HIFU: what is it?

High Intensity Focused Ultrasound (HIFU) is a non-surgical, non-invasive procedure that uses focused ultrasound waves to focus and heat specific areas of the body. It works by directing sound waves into an area of ​​tissue to create small, localized lesions. These lesions cause alterations in the affected tissues, leading to a host of therapeutic benefits, such as increased collagen production, improved circulation, and improved skin texture. HIFUs can be used to treat wrinkles, acne scars, enlarged pores, age spots, and other conditions related to aging skin. In addition, they are being studied for their potential use in the treatment of certain types of cancer.

HIFUs are part of therapeutic medicine for their safety.

In terms of safety and efficacy, HIFUs have been shown to be highly effective with minimal risk. The energy of the sound waves is precisely directed to a specific area of ​​tissue, without affecting the surrounding tissue. This allows doctors to focus the correct amount of energy to achieve the desired results without damaging nearby tissue. Also, recovery time for HIFU treatments tends to be shorter than traditional surgical procedures due to their non-invasive nature; patients can return to their normal activities soon after treatment without the need for downtime or extended healing periods after each session.

For a more natural effect and young skin without pain.

When used cosmetically on facial skin, HIFU treatments are generally considered a more natural option than more invasive surgical procedures like facelifts or injectables like Botox or fillers. Treatments also tend to last longer than those using injectables, since there is no need to repeat treatments over time.

Rather than having short-term effects that may require ongoing maintenance over the years, the effects of HIFU treatments tend to be more permanent due to their ability to stimulate collagen regeneration at deeper levels below the surface. of the skin in a single treatment session. .

Starting at age 40, you are entitled to a HIFU session to maintain a youthful appearance for years to come.

The main indications for anti-aging treatment with HIFU are:

  • Sagging facial skin.
  • visible wrinkles.
  • The jowls.
  • The marionette lines around the mouth.
  • Age spots.
  • Sun damage.

People with these types of signs of aging will usually see noticeable results after just one session. HIFUs can also be used to treat areas around the eyes, along the jawline, and neck, as well as other parts of the body affected by age-related changes, such as the arms, stomach, and thighs. .

HIFU: does this treatment have side effects?

Although there is no risk of surgical complications or long-term side effects associated with HIFU, some minor and temporary side effects may occur, such as: mild swelling, redness, irritation, and tenderness at the application site. These side effects usually last a few days or up to a week and should not pose significant health risks.

In addition to these common minor side effects, more serious long-term side effects have been reported, such as numbness or tingling in the treated area, as well as discoloration or scarring in some cases. However, these effects are rare and the researchers concluded that the overall safety profile of HIFU is quite high compared to other cosmetic treatments such as dermabrasion or chemical peels.

Are all skin types eligible for HIFU ultrasound anti-aging treatment?

This procedure is safe to use on all skin types! So whether you have oily, combination or dry skin, HIFU treatments can be an ideal option to combat wrinkles or restore lost volume to your face.
