Did you know that the loss of collagen in the body starts at 18-29 years old, after 40 years the human body can lose around 1% per year, and at around 80 years old the production of collagen in the body can decrease by 75 % overall compared to that of young adults? (1,2) But what is the role of collagen, the cause of its loss, and are there preventive measures to counter it?

What is the role of collagen?

A very important role because it is found throughout the human body in bones, tendons, ligaments, hair, skin and muscles. (Healing of wounds and tissues, repairing cornea, gums, scalp, also helps repair bones and blood vessels).

 

What contributes to the loss of collagen?

Some factors, among others, free radicals in the body, poor diet, tobacco, alcoholism and disease.
Free radicals - photoaging, the main subject of an article (3) specifying that it is a subset of extrinsic skin aging; the sun would influence this extrinsic skin aging and would play a role in the potential alteration of the normal course of intrinsic aging (natural or cellular).

The effects on the skin are readily apparent when comparing skin that is regularly exposed to the sun versus skin that hardly ever is. The aging process is also believed to be influenced by the formation of free radicals.

Loss of collagen is considered the hallmark finding of aged skin. Wrinkles and pigmentary changes are directly associated with photoaging and are considered to be its most prominent skin manifestations. These photo-damages are signs of premature aging.

Can we prevent photoaging?

The only well-known proposed strategies for preventing aging are: avoidance of the sun, use of sunscreens to block or reduce skin exposure to UV rays, use of retinoids (the term retinoids refers to with vitamin A and its derivatives).

Our essentials - Sunshine side

During…

An essential treatment: My mineral sun protection with shea butter & zinc oxide; this shea butter enriched with shea oil, vanilla oleoresin, CO2 sea buckthorn oil and essential oils of wild orange, petitgrain, neroli which help the skin to absorb the sun's rays, as well that a touch of vegetable glycerin which gives it a sublime texture and the zinc oxide, without nanoparticles, allows to block and reflect the rays of the sun!

After…

Essentials: After-sun for the body & the rose serum for the face. These serums feature at the top of the list, virgin rosehip (nicknamed plant collagen) which helps the skin to regenerate while giving it back the carotenes degraded in the sun, in order to properly repair what could have been damaged. Its regenerating activity coupled with a wealth of antioxidants attenuates wrinkles and smoothes superficial wrinkles. Its retinol content makes it a wonderful vegetable oil for the care of skin marked by the sun (premature aging) and is traditionally recommended for its skin repairing action.
