Highest-evidence picks

3-O-Ethyl Ascorbic Acid

Stable vitamin C derivative. Better pH stability than L-ascorbic acid; penetrates skin and converts to the active form. Antioxidant and brightening effect.

Azelaic Acid

Naturally derived dicarboxylic acid with antibacterial, sebum-regulating, and depigmenting properties. One of the few prescription-grade ingredients considered safe in pregnancy.

Hydroquinone

The strongest topical depigmenting agent. Inhibits tyrosinase and exerts cytotoxic effects on melanocytes. Prescription-only in many countries.

Glycolic Acid

Alpha-hydroxy acid (AHA) with the smallest molecular weight in the group. Accelerates desquamation, evens skin tone and texture.

Niacinamide

Vitamin B3 form with a wide action spectrum: brightens pigmentation, strengthens the barrier, minimizes pores, and reduces sebum production.

Salicylic Acid

Beta-hydroxy acid (BHA) with lipophilic properties: penetrates sebaceous glands, dissolves plugs, and exerts anti-inflammatory effects.

What to know

Brightening ingredients act at different steps of melanin synthesis. The classic gold standard is hydroquinone 4%, but it is prescription-only and banned in EU cosmetics due to side effects and the risk of ochronosis. Among OTC options, azelaic acid 10–20% delivers the best evidence base: clinical trials in melasma show it performs on par with hydroquinone, and it is safe in pregnancy.

Thiamidol is a new selective human tyrosinase inhibitor by Beiersdorf. Head-to-head clinical work showed efficacy comparable to hydroquinone and nearly 100× the enzyme affinity of kojic acid. Tranexamic acid 2–5% topically or 500 mg orally is a strong option for stubborn melasma, especially combined with SPF and azelaic acid.

Vitamin C works in several forms. L-ascorbic acid is the most potent but unstable, needs pH 2.5–3.5 and dark packaging. Derivatives (sodium ascorbyl phosphate, tetrahexyldecyl ascorbate, ethyl ascorbic acid) are more stable but less active. Vitamin C brightens post-inflammatory pigmentation and reinforces photoprotection – the key morning pairing with SPF.

Arbutin, alpha-arbutin, kojic acid, and glabridin are gentler tyrosinase inhibitors. They work, but effects take 3–4 months of consistent use to show.

One rule to follow: any brightening routine is pointless without daily SPF 30–50. UV triggers new pigmentation faster than actives can lift what is already there.

Frequently asked

How many brightening ingredients are in the Evigrade database?

Evigrade currently tracks 99 ingredients in the «brightening» category. Of those, 75 carry evidence tier A or B.

Which brightening ingredients are safe during pregnancy?

71 ingredients in this category are flagged as safe during pregnancy at typical cosmetic concentrations. 2 should be avoided. Always confirm the choice with an OB-GYN.

Which ingredients suit sensitive skin?

79 ingredients in this category show both low irritation potential and low allergen risk, making them safe even for reactive and sensitised skin. A patch test is still advisable before first use.

How should I start using ingredients from this category?

Start with a single high-evidence ingredient (tier A or B) at a low concentration, 2–3 times per week. After 2–3 weeks without reaction, frequency can be increased. Do not introduce two new actives at once – if skin reacts, you won't know which one caused it.
