Hydroquinone 4% cream is one of the most commonly used topical treatments for melasma, post-inflammatory hyperpigmentation, and uneven skin tone. Products such as Melalite are widely used in dermatology because hydroquinone directly targets excess melanin production.
Due to its strength, 4% hydroquinone is generally considered a medical-grade pigmentation treatment rather than a cosmetic brightening cream.

How Hydroquinone Works
Hydroquinone works by reducing melanin production in the skin:
- It inhibits the tyrosinase enzyme

The 4% concentration is considered highly effective for stubborn pigmentation because it provides stronger pigment suppression than lower concentrations.
Dermatologists often recommend it for:
- Moderate to severe melasma
- Persistent post-inflammatory hyperpigmentation
- Resistant dark spots (
Proper Application
Typical recommendations include:
- Apply once daily at night
- Use only on affected areas
- Combine with daily sunscreen use
Sun protection is essential during treatment because UV exposure may worsen pigmentation.
