What are the best anti-aging ingredients?

Some of the best anti-aging active ingredients include retinoids, which help increase collagen production and reduce the appearance of fine lines and wrinkles, as well as antioxidants like vitamins C and E, which help protect the skin from environmental damage. Other effective anti-aging ingredients include hyaluronic acid, which helps hydrate and plump the skin, and peptides, which can help stimulate the production of collagen and elastin. Additionally, using sunscreen can help prevent sun damage and reduce the appearance of skin aging.

To best guide you in choosing cosmetic products, here is a non-exhaustive list of the 4 best anti-aging active ingredients and their benefits.

 

Hyaluronic Acid: for hydrated, supple, and plump skin.

As we discussed in our complete article on hyaluronic acid, it is naturally present in the body. It helps maintain skin hydration and contributes to its tone. It is able to retain 1000 times its weight in water to deeply hydrate the skin, to plump it, and to smooth fine lines and wrinkles.

However, its quantity decreases sharply with age, which is why mature skin is drier and more fragile.
In cosmetics, there are different molecular weights for hyaluronic acid that will act on different levels:
- Ultra low weight or low molecular weight: it will act on wrinkles by penetrating the skin to absorb water and stimulate fibroblasts.
- High molecular weight: it will protect the skin from external agents such as pollution, UV rays, or cigarette smoke. The active ingredient will remain on the surface of the skin to act as a protective barrier.

The best approach is to use both hyaluronic acid weights to combine their effects. Anti-aging serums with hyaluronic acid can be used all year round, in any season, both morning and night.

 

Retinol: the star of anti-aging active ingredients

Retinol is a form of vitamin A commonly used in skincare products for its anti-aging properties. It belongs to the retinoid family and is one of the oldest and most renowned anti-aging active ingredients. It is the cosmetic active ingredient whose efficacy has been most extensively studied and proven.
Retinol was originally used to treat acne due to its strong anti-inflammatory power, then scientists realized its anti-aging power.

It is capable of both calming skin inflammations (like acne) and slowing down skin aging. More specifically, retinol acts on the skin's surface by eliminating dead cells, and also in depth by reactivating collagen and elastin.
- On the surface: it refines skin texture, brightens the complexion, and regulates melanocytes to reduce brown spots.
- In depth: it stimulates collagen and elastin production and increases hyaluronic acid concentration.

The main properties of retinol include:
- Collagen production stimulation: Retinol helps increase collagen production in the skin, which can improve the appearance of fine lines and wrinkles.
- Exfoliation: Retinol helps to increase cell turnover, which can improve skin texture and tone.
- Pore unclogging: Retinol can help to unclog pores and reduce the appearance of acne.
- Pigment reduction: Retinol can help to reduce the appearance of age spots and other forms of pigmentation.
- Antioxidant properties: Retinol has antioxidant properties that can help protect the skin from environmental damage.

It is important to note that retinol can cause skin irritation and sun sensitivity in some people, so it is recommended to use sunscreen when using retinol-based products. In addition, retinol is generally applied during the evening routine.

To achieve these beneficial effects on the skin, a significant concentration of Retinol is necessary (at least 0.3%), but this can be irritating for thin and dry skin. Be careful, retinol should not be taken lightly, it is a highly irritating active ingredient that will not suit everyone.

 

Vitamin C: for a radiant complexion

Vitamin C (ascorbic acid) is a powerful antioxidant and brightener commonly used in skincare products for its anti-aging properties.

The main properties of vitamin C include:
- Antioxidant properties: Vitamin C helps protect the skin from environmental damage caused by free radicals, which can lead to premature aging. It also combats oxidative stress.
- Stimulation of collagen production: Vitamin C helps to increase collagen production in the skin, which can improve the appearance of fine lines and wrinkles. Collagen and elastin are essential proteins for skin firmness and elasticity.
- Brightening effect: Vitamin C can help to brighten the skin and reduce the appearance of age spots and other forms of pigmentation. It decreases the production of melanin responsible for dark spots, which helps to restore radiance to the complexion.
- Protection against sun damage: Vitamin C can also help protect the skin from UV damage when used in combination with sunscreen.
- Anti-inflammatory properties: Vitamin C also has anti-inflammatory properties that can help soothe irritated skin.

It is thanks to all these properties that vitamin C is a key active ingredient in an anti-aging treatment. It will improve skin texture, brighten the complexion and reduce the dull complexion of smokers and stressed individuals.

Dermatologists recommend using this active ingredient primarily in the morning. It can be used on all skin types, even sensitive. However, be careful not to combine Vitamin C and Retinol if you have sensitive skin, as this could cause irritation. 

It is important to note that vitamin C is an unstable molecule and can be degraded by exposure to light, heat, and air. To get the most out of vitamin C, it is recommended to use it in a stable form, such as ascorbyl palmitate or sodium ascorbyl phosphate, and to store it in a cool, dry place.

 

Glycolic Acid: to improve skin quality and texture

Glycolic acid is an alpha-hydroxy acid (AHA) commonly used in skincare products for its exfoliating properties. It is a fruit acid obtained from sugarcane, beet, or grape extract.

It is the smallest fruit acid molecule, which gives it very good skin penetration to effectively stimulate cellular activity.
It increases cell renewal, so the complexion will be clearer and cleaner. Skin hydration is improved, as is the penetration of other active ingredients.

The main properties of glycolic acid include:
- Exfoliation: Glycolic acid works by breaking the bonds between dead skin cells, allowing them to be easily removed from the skin's surface. This can improve skin texture and tone, reduce the appearance of fine lines and wrinkles, and even out skin pigmentation.
- Stimulation of collagen production: Glycolic acid can also stimulate collagen production in the skin, which can help improve the overall appearance of the skin. This will give it a firming and toning effect.
- Unclogging pores: Glycolic acid can help unclog pores and reduce the appearance of acne.
- Hydration: Glycolic acid can help increase skin hydration, which can make the skin look plumper and younger.
- Brightening effect: Glycolic acid can also help brighten the skin, which can make it look more radiant and even.
Glycolic Acid can be used on all skin types (young or mature, oily or normal) as an evening treatment (however, avoid during periods of significant sun exposure or irritated skin). The concentration in cosmetics, ranging from 4% to 15%, should be chosen according to the tolerance of each skin type. It is important to note that glycolic acid can cause skin irritation and sun sensitivity in some people, so it is recommended to use sunscreen when using glycolic acid-based products and to start with lower concentrations.

- For young and oily skin, it will help to regulate sebum.
- For more mature and dry skin, it will act as a moisturizer, anti-wrinkle, and brightener.

 

The most important thing: good sun protection!

Gone are the 70s and 80s fashion where you had to be the most tanned to show off a radiant complexion and "crêpe" on the beach without sun protection! You'll only end up with wrinkled skin, guaranteed, and hello Gollum.
The sun, of course, is necessary, but if you want to maintain beautiful skin, you should protect yourself as soon as you expose yourself.

Sunscreen is considered one of the best anti-aging protections due to its ability to protect the skin from the harmful effects of UV rays. Photoaging can cause fine lines, wrinkles, and age spots. The sun's UV rays can cause various skin damages, including sunburn, dark spots, and premature aging. Sunscreen can also help protect the skin against skin cancer, which is caused by prolonged exposure to UV rays.

It is recommended to use a sunscreen with an SPF of at least 30 that offers broad-spectrum protection, meaning it protects against both UVA and UVB rays, and to reapply it every 2 hours when exposed to the sun.
The use of a photoprotective formula is essential at any age.
The right timing: in the morning, hydration and sun protection; in the evening, deep cleansing and activation because the skin regenerates at night.

 
In conclusion, we understand that all these active ingredients will address different aspects of aging, so the best approach is to combine them for a multiplied effect.
