Questions / Answers
  • 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 ;
    - Botox injections for deep expression wrinkles.
    - 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.

The skin ages...WHY?



INTRINSIC AGING


This is a natural, genetically programmed process that is the result of slow tissue degeneration, determined by a person's genetic makeup.
This "biological clock" does not tick at the same rhythm for everyone.





EXTRINSIC AGING

Caused by several environmental factors, such as sun exposure, pollution, stress, smoking, etc.

The main factors:

  • The sun and its UV rays: photo-aging is the premature aging of the skin caused by repeated exposure to ultraviolet rays from the sun or from artificial sources, causing permanent effects that are both superficial and profound. 
  • The environment: pollutants in the atmosphere weaken the skin's protective hydrolipidic film, and generate free radicals with high oxidizing power, contributing to an accelerated aging of the skin. The harmful effects of pollutants are evident in the short term, but also in the long term, with the cumulative effects of low-intensity, but repeated aggression from pollutants. 
  • Lifestyle: smoking, stress, excess alcohol, unbalanced diet, etc. An unhealthy lifestyle can cause the skin to lose its vitality and glow.

One particular effect is that it becomes shriveled due to stress or fatigue, provoking muscular tension and therefore the appearance of creases and wrinkles. Overworking or an insufficient diet can force the cells to draw excessively from the reserves in the dermis to nourish themselves. This creates a situation where the skin lacks essential elements: vitamins, trace elements, essential fatty acids...

 

HOW ?  WHAT WE CAN SEE... AND WHAT IS HAPPENING...


The signs of age change as life goes on.



  • The first signs of skin aging- wrinkles and fine lines, a lack of radiance in the skin tone and a loss of elasticity - begin to appear.

These signs are linked to a slowdown in skin cell metabolism and to repeated attacks from free radicals: oxidizing agents, among others, triggered by exposure to UV rays.




 

  • Next, wrinkles form deep furrows and the skin loses firmness.

These signs of aging are essentially linked to the disappearance of collagen fibers and a lack of hyaluronic acid, the fundamental substance of the dermis.





 

  • Finally, mature skin loses its density, vitality and comfort.

With time, the synthesis of the skin's essential components slows down:
- Hyaluronic acid and collagen, key skin-support molecules, are also reduced. The skin's structure becomes more fragile, loses density and begins to sag.
- The skin also becomes dry, and the natural synthesis of skin lipids is decreased.





PREVENTION : A MUST

We might not be able to slow down time or prevent the stressful events of life, but we can nonetheless act on photo-induced aging, triggered by the skin's exposure to ultraviolet rays, which cause almost 90% of skin aging.
In reality, excess sun exposure should be avoided from birth. But it's never too late to start doing the right thing.

Preventing photo-aging means using sun protection, i.e. being constantly prudent concerning sun exposure: avoid exposure to extremely bright sunshine, wear suitable clothing, hats and sunglasses, use sun care products with high sun protection.
And don't forget, children less than 3 years old should NEVER be directly exposed to the sun.
