peptides vs retinol
What Exactly Is a Peptide In Skincare?
Peptides are tiny biological compounds made up of two or more amino acids linked together in a chain. Peptides that are naturally joined together produce proteins (also known as "polypeptides"), which are the molecules responsible for practically every cell function. Collagen, the most prevalent protein in the human body, is essential for skin health and lifespan. The dermis (middle) layer of the skin is very crucial for skin lifespan because it contains collagen-producing fibroblast cells. Collagen production and consequent collagen levels in the skin are commonly considered to decline with age, resulting in skin changes such as fragility, increased fine lines and wrinkles, drooping, and loss of elasticity.
Peptide discovery and research is an exciting area of cutting-edge skincare. The main concern, however, is how to employ peptides in skin care. Because direct collagen supplementation to skin is challenging, skincare science has effectively discovered peptides that can stimulate collagen production on a genetic level to rejuvenate skin from the inside out.
Here are a some major peptide actors gaining popularity for their collagen-boosting qualities.
Copper peptides act as a signal to the skin, causing it to develop collagen and elastin.
Copper peptides, by hydrating and renewing skin cells, may aid to decrease the appearance of fine lines and wrinkles and level out your skin tone.
- Palmitoyl pentapeptide-4 is another another well-known peptide.
This chemical, also known as Matrixyl, has been demonstrated in multiple biologically relevant studies to minimise wrinkles and promote skin suppleness.
What Exactly is Retinol in Skincare?
Retinol is a vitamin A derivative also known as retinoic acid. Vitamin A is essential for the homeostasis of the central nervous system and the immunological system, and it also contains antioxidant qualities. Retinoids are commonly found on ingredient lists as tretinoin, retinol, retinal, retinyl palmitate, or retinyl acetate, and their concentration might have undesirable side effects on your skin. Retinoids function by increasing skin cell turnover and collagen production.
When retinol is used, dead skin cells on the skin's surface are replaced with younger ones. Unfortunately, high cell turnover can temporarily weaken the skin barrier after each usage, leaving your skin and body susceptible for a short period of time, therefore good skin care after retinol use is crucial for enabling the skin barrier to heal.
Some stronger retinoids are prescribed by doctors to treat more resistant skin issues such as severe acne, fine wrinkles, and/or dark spots in order to balance out skin tone and improve overall skin texture.
However, retinoid usage can (often) cause skin irritation, dryness, sensitivity, flaking, and increased sensitivity to the sun.
