What are the functions of polypeptide hyaluronic acid?
I am a 30-year-old woman. Fine lines have started to appear on my skin. I heard that peptides and hyaluronic acid can improve these issues, but I have many questions regarding their actual effectiveness and whether they are suitable for my skin.

Peptide hyaluronic acid functions include moisturizing, promoting collagen synthesis, regulating sebum secretion, and anti-inflammatory effects.
1. Moisturizing: Peptide hyaluronic acid is hydrophilic and has water-locking properties, enabling it to absorb and retain moisture, allowing water to remain in the stratum corneum for extended periods and forming a protective film, thereby achieving moisturizing effects.
2. Promoting collagen synthesis: Peptide hyaluronic acid can stimulate the biosynthesis of extracellular matrix proteins such as collagen and elastin, helping to maintain skin elasticity and firmness. Collagen is an essential component of the skin and plays a crucial role in maintaining youthful skin appearance and repairing damaged skin tissues.
3. Regulating sebum secretion: Peptide hyaluronic acid has a certain moisture-absorbing capacity, which can reduce the water content on the skin surface, thereby inhibiting sebaceous gland oil secretion to some extent. For individuals with oily skin or acne, this helps improve skin quality and reduce skin problems caused by excess oil production.
4. Anti-inflammatory: Peptide hyaluronic acid can modulate immune responses and inhibit the production and release of inflammatory factors, thus exerting certain anti-inflammatory effects. This provides some auxiliary therapeutic benefits for individuals with skin inflammation issues.
