Peptide
Signaling molecules that can stimulate collagen production and improve skin firmness.
Can I mix Peptide with other ingredients?
AHAs can reduce peptide effectiveness. Best to use acids and peptides in separate routines for maximum benefit.
BHA's acidic pH may reduce peptide effectiveness. Consider using in separate routines (acids AM, peptides PM).
Vitamin C's low pH may reduce peptide effectiveness. Copper peptides in particular may bind with vitamin C and reduce its potency. Consider waiting a few minutes between them or using in separate routines.
Peptides and ceramides are both gentle and reparative. A perfect combo for anti-aging without irritation.
Hyaluronic acid + peptides is a hydrating anti-aging duo. Apply HA first (thinner), then peptide serum.
Peptides and niacinamide both support the skin barrier and collagen. Safe and beneficial to combine.
Retinoid + peptides is a powerful anti-aging duo. Peptides signal collagen production while retinoids boost cell turnover.
Growth Factors
Growth factors and peptides work through complementary pathways. EGF/PDRN signals cell repair while peptides boost collagen synthesis.
