Cos De BAHA 2% Hydroquinone Brightening Serum 30ml (HB)

Cos De BAHA 2% Hydroquinone Brightening Serum (HB) is a lightweight, fast-absorbing brightening serum formulated as a targeted dark spot corrector and melanin-inhibiting treatment for visibly uneven skin tone.

This is a PM-only serum best applied after cleansing and toning, before moisturizer. Always follow with broad-spectrum SPF the next morning. Use every other day to start, building up to daily application. Cycle off after 60 days of continuous use with a 30-day break.

The formula leads with 2% Hydroquinone, the gold-standard melanin suppressant, reinforced by a trio of brighteners — Arbutin, Kojic Acid, and Niacinamide — for a compounding lightening effect. Salicylic Acid and Lactic Acid gently resurface to accelerate cell turnover, while Sodium Hyaluronate and Aloe Barbadensis Leaf Extract maintain hydration and calm sensitivity. Antioxidant botanicals including Rosemary, Witch Hazel, and Eucalyptus round out the formula with protective, soothing support.

• Visibly reduces dark spots, melasma, post-acne marks, and freckles with consistent use — initial results typically within 4 weeks.
• Inhibits melanin production at the source through a multi-pathway brightening approach targeting melanocyte activity.
• Gently exfoliates the skin’s surface to improve texture and enhance absorption of brightening actives.
• Soothes & hydrates while active ingredients work, reducing the risk of irritation common with standalone hydroquinone formulas.

How to Use: Always patch test before first use. Apply a small amount to clean, dry skin at night every other day for the first week, then progress to nightly use as tolerated. Avoid contact with eyes. Use broad-spectrum sunscreen every morning without exception. Discontinue use after 60 consecutive days and resume after a 30-day break. If irritation develops, reduce frequency or stop use entirely.
