Can I mix hydroquinone with other ingredients?

CautionAM only

General guidance

Hydroquinone reduces your natural UV defense. Always use strong SPF in the morning with hydroquinone.

Caution

Benzoyl Peroxide

Both can cause temporary skin staining when combined. If using together, let each fully absorb before applying the next.

AHAs (Glycolic, Lactic, etc.)

AHAs increase hydroquinone penetration, which can cause more irritation. Use lower concentrations if combining.

Caution

Retinoids

Hydroquinone and retinoid together is a clinical protocol but increases irritation. Use under dermatologist guidance.

Caution

Vitamin C

Both target hyperpigmentation through different paths. Together they can irritate. Alternate AM/PM for best results.
