Glycerin is a naturally derived humectant—a ingredient that draws moisture from the air into your skin. It's one of the most widely used and well-studied moisturizing agents in skincare, helping skin feel softer and more hydrated.
Benefits
Attracts and retains moisture in the skin
Improves skin hydration and softness
Helps strengthen skin barrier function
Suitable for most skin types, including sensitive skin
Science: The Cosmetic Ingredient Review Expert Panel concluded glycerin is safe as used in cosmetics across all concentrations. Research shows glycerin effectively improves skin hydration and is well-tolerated with minimal irritation risk. It is also referenced in clinical guidelines for managing inflammatory skin conditions and maintaining skin integrity.
Kojic acid is a natural compound produced by fungi that works by slowing down melanin production in your skin. It's commonly used in skincare products designed to reduce the appearance of dark spots, discoloration, and uneven skin tone.
Benefits
Helps fade dark spots and hyperpigmentation
May reduce melasma (brown patches on face)
Has antimicrobial and antioxidant properties
Works well as an add-on treatment alongside other skincare ingredients
Potential concerns
Can cause irritation or sensitivity in some users
May cause contact dermatitis with prolonged use
Effectiveness is modest and often requires combination with other treatments
Limited long-term safety data available
Science: Clinical evidence shows kojic acid is effective as an adjuvant (supporting) therapy for melasma and dark spots with minimal side effects, though it is less potent than hydroquinone. Research indicates good tolerability, but most studies had small sample sizes and lacked long-term follow-up data.
