[04] COSRX - BHA BLACKHEAD POWER LIQUID 100G

A cult-favorite chemical exfoliant that penetrates deep into pores to unclog them, reduce blackheads, and refine skin texture using betaine salicylate (a gentler BHA).

Suitable for Skin Type:

• Oily and combination skin

• Acne-prone skin

• Textured skin or skin with enlarged pores

• Not ideal for very dry or sensitive skin unless well-acclimated to BHAs

What Will It Achieve?

• Unclogs pores and removes blackheads and whiteheads

• Exfoliates inside the pore lining

• Helps reduce breakouts and sebum build-up

• Refines skin texture and minimizes the appearance of pores

• Improves the penetration of other products

Key Ingredients:

• Betaine Salicylate (4%) – A gentler alternative to salicylic acid, exfoliates inside pores

• Willow Bark Water – Natural source of salicylates

• Niacinamide – Brightens and supports skin barrier

• Panthenol – Hydrating and barrier-repairing

• Sodium Hyaluronate – Adds hydration to prevent over-drying

Best Used Morning or Evening Routine?

• Preferably Evening (PM)

• Can be used in the morning, but must wear SPF

• Start with 2–3 times a week, increase as tolerated

Complimented By:

• Hydrating toners (e.g., hyaluronic acid, rice toner)

• Calming serums (e.g., centella, panthenol)

• Non-comedogenic moisturizers

• Niacinamide and azelaic acid (in alternating routines)

Avoid Layering With:

• Other strong exfoliants (AHA/BHA/PHA), retinol, or vitamin C in the same routine

• Physical scrubs or peel pads on the same day

• Harsh cleansers that strip the skin

Which Step in the Skincare Routine Does It Belong?

• After cleansing and toning (or as your exfoliating toner step)

• Follow with serums, moisturizer, and SPF (if AM)

Caution (Things to Be Aware Of):

• Introduce gradually – overuse can irritate and impair the barrier

• May cause purging in the beginning (due to pore clearing)

• Do not use on broken or sensitized skin

• Always use broad-spectrum SPF during use

• Patch test if you’re new to acids

Instructions (How to Use):

1. After cleansing and toning, apply 1–2 pumps to a cotton pad or hands

2. Gently swipe across the face, focusing on blackhead-prone areas (e.g., T-zone, chin)

3. Pat gently until absorbed

4. Follow with a hydrating serum or moisturizer

5. Use 2–3 times per week, then increase frequency if your skin tolerates it

6. Use sunscreen the next morning
