COSRX BHA Blackhead Power Liquid 100ml is a leave-on Korean chemical exfoliant formulated with 4% Betaine Salicylate and Willow Bark Water to gently dissolve blackheads, unclog congested pores and refine uneven skin texture. This cult-favourite K-beauty treatment from COSRX targets the T-zone, controls excess sebum, fades post-blemish marks with added Niacinamide, and reveals a noticeably smoother, brighter complexion without the harshness of physical scrubbing.
Why This BHA Liquid Works
Beta Hydroxy Acids are oil-soluble, which means they penetrate deep into pores and dissolve the sebum, dead skin cells and debris trapped inside. Unlike harsh scrubs, this leave-on liquid works at the source of congestion. The 4% Betaine Salicylate (roughly equivalent to 2% salicylic acid) loosens blackheads from within while soothing botanicals keep skin calm and hydrated.
Ideal For
This BHA treatment is ideal for oily, combination and blackhead-prone skin, including those struggling with clogged pores, dull T-zone congestion or stubborn closed comedones. Suited to intermediate acid users in the UAE looking for a gentle daily exfoliant. Avoid pairing with high-strength AHAs, retinoids or vitamin C on the same evening, and patch test first if your skin is sensitive or aspirin-allergic.
Each active ingredient is chosen for a clinical role in pore care:
• 4% Betaine Salicylate (BHA): A gentle plant-derived form of salicylic acid that exfoliates inside the pore to dissolve blackheads and reduce visible congestion.
• Willow Bark Water (Salix Alba): A natural BHA source that boosts exfoliating action while soothing irritation and replacing plain mineral water in the base.
• Niacinamide: Brightens uneven tone, fades post-blemish marks and supports the skin barrier alongside the acid action.
• Sodium Hyaluronate and Panthenol: Hydrate, soothe and reinforce moisture levels so exfoliation never leaves skin feeling stripped or tight.
For best results, build tolerance gradually:
1. Cleanse and tone as usual, then dispense the liquid onto a cotton pad or fingertips.
2. Swipe a thin layer over the T-zone, chin and any congested areas, avoiding the eye area.
3. Pat in gently and allow full absorption before the next step. Start once a week, then increase to two to three times a week as skin adjusts.
4. Always finish with broad-spectrum SPF the next morning, as chemical exfoliants increase sun sensitivity.
