3-O-Ethyl Ascorbic Acid is a stable, water-soluble ethylated derivative of vitamin C that converts to ascorbic acid in the skin, providing antioxidant protection and supporting collagen synthesis and pigmentation control. It is valued for greater stability than pure L-ascorbic acid while delivering similar brightening and anti-aging benefits.
Lactobacillus Ferment Lysate is a postbiotic ingredient made from the broken-down (lysed) cells of fermented Lactobacillus bacteria. It is used in skincare to support the skin barrier, modulate the skin microbiome, and provide soothing and antioxidant benefits.
Gluconolactone is a polyhydroxy acid that gently exfoliates the skin surface, provides antioxidant and humectant benefits, and is often considered milder than alpha hydroxy acids. It is well tolerated, including by sensitive skin, due to its larger molecular size and slower penetration.
Carnosine is a naturally occurring dipeptide (beta-alanine and L-histidine) used in skincare for its antioxidant and anti-glycation properties, helping protect against oxidative stress and protein cross-linking associated with skin aging. It is typically incorporated into serums and creams at low concentrations as a supporting active.
Niacinamide (vitamin B3) is a water-soluble active that supports the skin barrier, regulates sebum, brightens hyperpigmentation, and reduces inflammation. It is widely tolerated across skin types and used in concentrations commonly ranging from 2% to 10%.
Allantoin is a naturally derived or synthetically produced compound used in skincare for its soothing, moisturizing, and keratolytic (skin-softening) properties. It promotes cell proliferation and helps calm irritation, commonly appearing in creams, lotions, and after-sun products.
