Start here: gentle and effective
Alpha Arbutin
A skin-friendly relative of hydroquinone that slows melanin production. It fades dark spots and tanning gradually with very little irritation.
Bakuchiol
A plant extract (from babchi seeds) that works like retinol in small studies, with far less dryness and no sun sensitivity. It is milder and slower than a true retinoid.
Glutathione
A popular "glow" antioxidant in India. Topically it has some evidence for mild brightening, but it is a large, unstable molecule. Expect modest results compared with vitamin C, arbutin or niacinamide.
Licorice Extract
Licorice root (mulethi) contains glabridin, which gently inhibits pigment production, and glycyrrhizinates, which calm redness. It is a mild brightener suited to sensitive skin.
Stronger options (introduce slowly)
Glycolic Acid
The smallest alpha-hydroxy acid, so it penetrates deepest. It dissolves the bonds between dead skin cells for smoother, brighter skin and fades marks, but it is the AHA most likely to sting. Use 2–3 nights a week after cleansing. Skip it on nights you use retinoids. Sunscreen is non-negotiable because AHAs raise sun sensitivity.
Hydroquinone
The strongest topical depigmenting agent, used for melasma and stubborn dark spots. It blocks melanin production, but it must be used in short, supervised courses: long-term use can cause irritation and, rarely, ochronosis (blue-black darkening). Use only under a dermatologist's guidance, typically nightly on the dark patches for up to 3 months, then take a break. Strict daily sunscreen is required or results reverse.
Retinal
Retinaldehyde is one conversion step closer to retinoic acid than retinol, so it works faster than retinol while usually being gentler than tretinoin. It also has a mild antibacterial effect useful for acne. Start at 0.05% two or three nights a week and build up slowly. Buffer with moisturiser if you are sensitive, and wear SPF daily.
Vitamin C
A powerful antioxidant that brightens dull skin, fades dark spots and boosts your sunscreen's protection against free radicals. Pure L-ascorbic acid works best at a low pH and oxidises (turns orange) quickly. Apply in the morning on clean skin before moisturiser and sunscreen. Store it away from light and heat, and throw it out once it turns dark orange.
