Elastin

Elastin is a fibrous protein essential for skin elasticity and resilience. Present in the dermis, it allows tissues to stretch and then return to their original shape, much like a biological spring. Its synthesis peaks during childhood and then gradually declines with age, contributing to the skin’s loss of suppleness and the appearance of wrinkles.

Everything you need to know about elastin.

Naturally present in connective tissues, elastin is a protein essential to skin structure that allows it to regain its shape after each stretch. However, its production decreases over time, contributing to skin laxity. Elastin is also used in certain cosmetic products, but this raises several questions. How is it obtained? What are its benefits when applied topically? Does its use require any special precautions? Continue reading to learn more about elastin.

Collagen and elastin: the proteins synonymous with flexibility and firmness.

These two proteins are essential for the firmness, elasticity, and skin resilience. Often confused due to their similar functionalities, they nevertheless act differently to preserve the overall health of the skin.

FAQ about elastin

What is the difference between elastin and collagen?

Collagen gives the skin its strength and structure, while elastin allows it to stretch and return to its original shape. Together, these proteins form the primary support of the dermis.

What factors contribute to the degradation of elastin?

UV rays, smoking, pollution, and free radicals are the primary factors responsible for the degradation of fibers of elastin. They activate enzymes called elastases, which destroy these structures.

Can applying elastin topically restart the skin’s natural production of elastin?

Applying elastin to the skin generally does not reactivate natural elastin synthesis, as this protein’s molecular weight is too high to penetrate the skin barrier. However, certain fragmented forms such as elastin peptides or hydrolyzed elastin have shown in studies in vitro, they could stimulate fibroblast activity, the cells responsible for its production. These results, however, still need confirmation in vivo.

Are elastin-based dietary supplements effective?

Dietary supplements based on elastin currently lack solid scientific evidence demonstrating their efficacy on the skin. Although some individuals report more supple, better-hydrated skin after a regimen, these effects remain subjective and have not been confirmed by published clinical studies.

Can cosmetic elastin be vegan?

Traditionally derived from animal sources, elastin is today replaced by alternatives obtained by fermentation from amino acids, but which are not of plant origin. These versions reproduce the properties of natural elastin and offer similar skin benefits, without resorting to animal products.
