There are two categories to keep in mind: 1 Retinoids derived from vitamin A
• Some retinoids are topical medications that require a prescription.
• Others like Retinaldehyde are classified as dermo-cosmetics and are available without prescription. Through a physiologic conversion into active vitamin A, based on the needs of the skin, Retinaldehyde works deeply to boost cellular metabolism and on the skin surface to brighten the complexion. 2 Hyaluronic acid A major component of the skin matrix, it is synthesized by the cells of the epidermis (keratinocytes) and of the dermis (fibroblasts). This synthesis decreases with age. However, the support role of hyaluronic acid is critical: It ensures skin suppleness, elasticity and its hydration. Today, dermo-cosmetic products are available to compensate for this decrease by increasing Hyaluronic acid concentration in the skin.

The main techniques include :
- Peelings, of variable depths ;
- Laser dermabrasion, various techniques ;
- Exposures to various types of light, laser and non-laser ;
- Injections with wrinkle fillers: Collagen or Hyaluronic acid ;
- Cosmetic surgery: In some cases, face and neck lifts, eyelid surgery (blepharoplasty), are justified.
The decision to use one technique over another is based on individual consultation. There are differences in skin aging, expectations and needs.

At menopause, there is a cessation of ovarian secretion, including estrogen which plays a positive role on skin tone and thickness. Therefore, menopause is one of the factors in skin aging but less important than sun exposure.

It is proven that smokers experience skin changes that lead to premature skin aging: wrinkles, yellow complexion (more reasons to stop smoking or not start).

Many dietary supplements contain vitamins, amino acids and minerals and claim anti-aging properties, usually through protection from free radicals.

Yes, indeed, it is impossible to have the same skin at 60 than at 20. However, what we discussed earlier makes it possible to correct consequences of skin aging, specifically related to sun exposure. So keep smiling, an excellent anti-aging!

In time, the skin loses its structure. As a result, it gets dehydrated more easily, more fragile and it is more vulnerable to external aggressions (climatic, pollution, ill-suited skin products …). It is therefore necessary to moisturize it using the right dermo-cosmetic products and restore its defective hydrolipidic film.
