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.
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!
THE SKIN AGES ... WHY ?
Day after day, time leaves its mark at different rates which shows that we are not all created « equal ». Skin aging is there to remind us in a visible, sometimes cruel way.
Many factors are responsible for these changes, from lifestyle to genetics.
HOW ? WHAT IS VISIBLE ...
Marks of time vary during one’s life.
From 25 to 50 years of age, the skin gets thinner, weaker, loses its radiance. Its natural brightness tends to decrease.
A few fine lines and expression lines appear here and there; around the eyes and the lips…
Around the age of 50, lines become more pronounced, the skin is not as firm, facial contour less even, the neck less tight.
WHAT HAPPENS ...
These marks of time are caused by a change or a gradual decrease in collagen fibers, elastin, hyaluronic acid and the dermis fundamental substance, together with increased skin dryness.
Skin aging obeys the same rules as other organs but the skin is also exposed to specific aggressions (tobacco…). Repeated free-radicals (oxidizing agents) attacks from UV exposure add to cell metabolism slow down as part of the aging process. As a consequence, certain areas (face, neck, back of the hands, forearms) age more quickly.
PREVENTION : ESSENTIAL !
While we cannot slow down time or avoid stressful events in our lives, we can have an effect on photo-induced aging (caused by skin exposure to UV rays).
Actually, one has to be careful with overexposure to the sun starting early in life. But it is never too late to start.
Photo-aging means photo-protection, that is to always be careful about sun exposure: Do not spend much time in bright sun, wear clothes, a hat and sunglasses (that carry a UV label), use high SPF sunscreens.
Of course, don’t forget that a child under the age of 3 should NEVER be exposed to the sun.
