Research Summary
Skin plays an essential role in our personal image and aesthetics, as it is where the first signs of aging become visible. To prevent and mitigate this natural physiological process and achieve a more youthful appearance, consumers are constantly searching for innovative anti-aging skincare products, including more effective and safer ingredients. Peptides, in particular, have gained attention as cosmetic ingredients in anti-aging formulations due to their efficacy in reducing wrinkles and hyperpigmentation and stimulating collagen production. Additionally, peptides are less irritating alternatives to conventional cosmetic ingredients used for combating skin aging.
However, despite these advantages, peptides face considerable challenges in penetrating the stratum corneum, which limits their bioactivity. This is due to their high molecular weight, hydrophilic character, and susceptibility to enzymatic degradation. As a result, formulation technologies are necessary to improve the stability and release pattern of peptides through the skin. A detailed overview focused on smart and multifunctional nanodelivery systems used to encapsulate peptides in anti-aging skincare formulations is provided within the scope of research and development for anti-aging skincare products.
In summary, peptides are demonstrated to be a reliable and outstanding alternative to retinoids and sunscreens in the fight against skin aging.
