COSRX BHA - Blackhead Power Liquid - 100ML

Unclog. Refine. Clear.

Blackheads, congested pores, and stubborn sebum plugs — meet your match. The COSRX BHA Blackhead Power Liquid is a targeted chemical exfoliant formulated with 4% betaine salicylate, a gentler yet highly effective BHA that penetrates deep inside the pore to dissolve the buildup that causes blackheads, whiteheads, and congestion. Unlike harsh physical scrubs, this leave-on liquid works quietly overnight to refine pore appearance, smooth uneven texture, and reveal visibly clearer skin — without the irritation. The kind of results you can actually see.

How to Use

1. Use in your evening routine, after cleansing.
2. Soak a cotton pad with the liquid and sweep gently across the face, focusing on congested areas (nose, chin, forehead).
3. Do not rinse out — this is a leave-on exfoliant.
4. Allow to absorb for at least 20 minutes before applying the rest of your routine.
5. Follow with toner, serum, and moisturiser.
6. Use 2–3 times per week to start, increasing frequency gradually as your skin builds tolerance.
7. Always apply SPF 30+ the following morning — BHA increases photosensitivity.

Important: Do not use on the same evening as other exfoliants (AHA, retinol, retinal). Allow skin to adjust before combining actives.

Tip: Apply to a slightly damp face for a gentler effect, or dry skin for a more intensive exfoliation — ideal for targeting stubborn blackheads on the nose.

Key Ingredients

• Betaine Salicylate (4%) — A gentler, skin-derived form of salicylic acid (BHA) that penetrates oil-filled pores to dissolve blackheads, sebum plugs, and dead skin cell buildup from the inside out. Effective yet significantly less irritating than traditional salicylic acid, making it suitable for sensitive skin types.
• Willow Bark Water (Salix Alba) — A natural source of salicin that provides additional gentle exfoliating and anti-inflammatory benefits, soothing the skin while the BHA works.
• Niacinamide — Minimises the appearance of pores, controls sebum production, and brightens post-acne marks — complementing the pore-clearing action of BHA for a visibly refined complexion.
• Panthenol (Vitamin B5) — Soothes and hydrates the skin during exfoliation, reducing potential irritation and keeping skin comfortable and balanced.
• Allantoin — Calms inflammation and promotes skin cell renewal, helping to repair the skin barrier after exfoliation.
