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%.
Salicylic acid is a lipid-soluble beta-hydroxy acid that exfoliates the skin surface and penetrates sebaceous pores to loosen and dissolve keratin and debris. It is widely used to treat acne, blackheads, and conditions involving thickened or scaly skin.
Lactic acid is an alpha-hydroxy acid that exfoliates the skin by loosening bonds between corneocytes, promoting cell turnover, and acting as a humectant to improve hydration, texture, and tone. It is commonly used at concentrations ranging from low (hydration) to higher peel-strength formulations.
Centella Asiatica Extract is a plant-derived ingredient rich in triterpenoids (asiaticoside, madecassoside, asiatic and madecassic acids) used to calm inflammation, support wound healing, and strengthen the skin barrier. It is also valued for antioxidant and collagen-supporting properties in topical formulations.
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.
Malic acid is a naturally occurring alpha hydroxy acid (AHA) derived from fruits such as apples, used in skincare to exfoliate the skin surface, improve texture, and promote cell turnover. It is often combined with other AHAs and acts as both an exfoliant and a humectant.
