AHA + BHA + Charcoal Serum

Serenvit AHA + BHA + Charcoal Serum is BIOSAR's exfoliating evening serum for blemish-prone, congested skin. AHA loosens dull surface cells; Salicylic Acid (BHA) unclogs pores; Niacinamide regulates sebum; Activated Charcoal supports a clearer-looking finish. Use it as a targeted evening step two to three times a week, building up as tolerated. Always pair with a daily SPF30+ in the morning. Not for use alongside Retinol on the same night. Suitable for adults with oily and combination skin.

Why it works

Rough texture and clogged pores don't stand a chance. AHA resurfaces the surface, Salicylic Acid and BHA dive deep to clear congestion, and Charcoal draws out impurities while Niacinamide keeps skin balanced on a soothing Aloe Vera base. Pores look refined, texture looks smoother, and skin looks clearer and freshly renewed.

Proven Benefits

What this product does for your skin

  • Clearer complexion

    Activated Charcoal supports a clearer-looking, decongested evening finish.

  • Exfoliated texture

    AHA loosens dull surface cells for smoother-feeling skin.

  • Unclogged pores

    Salicylic Acid unclogs pores on blemish-prone, congested skin.

  • Balanced sebum

    Niacinamide regulates sebum across oily and combination skin.

How this formula works

The deep clean that resurfaces without leaving skin feeling stripped

Charcoal draws out the look of congestion while AHA, BHA and Salicylic Acid resurface dull, uneven texture for a clearer finish. These are assertive actives, so Niacinamide steadies the skin and a generous Aloe Vera base keeps the whole step comfortable rather than harsh. The result is one purifying drop that leaves pores looking refined and the surface smooth, not raw.
