## Why this fit

- This serum offers excellent plumping and firming for your combination skin, as multiple bio-mimicking peptides and sodium hyaluronate work synergistically to improve elasticity and volume. The inclusion of zinc PCA also aids in seboregulation, making it highly suitable for your skin type. Additionally, peptides like Sh-Polypeptide-1 and Sh-Oligopeptide-2 support skin repair and regeneration, offering benefits for your acne, blemishes, and breakouts. The product demonstrates a high safety profile with no risks of irritation due to the absence of harsh ingredients and the presence of soothing components like panthenol and sodium hyaluronate.

([American Journal of Clinical Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12113650/))
- Topical application of 0.1% hyaluronic acid formulations of different molecular weights led to significant improvements in skin hydration and elasticity, with low-molecular-weight formulations also significantly reducing wrinkle depth in seventy-six female subjects compared to a vehicle control. ([Journal of Drugs in Dermatology, 2011](https://pubmed.ncbi.nlm.nih.gov/22052267/))

([Clinical Oral Investigations, 2022](https://pubmed.ncbi.nlm.nih.gov/34623507/))
- Treatment with a hyaluronic acid-containing mouth rinse or topical gel led to significant lesion reduction, pain relief, and normalization of lesion color in adult patients with minor recurrent aphthous stomatitis, with the gel formulation showing an earlier healing onset at 3 days. ([BMC Oral Health, 2019](https://pubmed.ncbi.nlm.nih.gov/31311529/))

- Mangifera indica extract reduced lipid production by 40% in sebocytes, improved sebum quality and quantity in Caucasian volunteers, reduced porphyrins expression, and decreased C. acnes lipase activity by 29% compared to placebo while protecting microbiota equilibrium. ([Molecules, 2022](https://pubmed.ncbi.nlm.nih.gov/35897945/))
