COSRX BHA Blackhead Power Liquid (50 ml)
Product Overview
The COSRX BHA Blackhead Power Liquid is a highly celebrated, targeted chemical exfoliant designed to clear stubborn congestion from deep within the skin. Specifically formulated for oily, acne-prone, and large-pore skin types, this fluid works to dissolve blackheads, control excessive oil production, and prevent new acne breakouts before they surface.
Key Benefits
-
Targeted Pore Clearing: Penetrates deep into the lining of the pores to dissolve dead skin cells and hardened sebum, effectively melting away blackheads and whiteheads.
-
Sebum Regulation: Dramatically reduces excess oil production, especially in the T-zone, preventing the shiny, greasy look throughout the day.
-
Acne Prevention: By keeping the pore lining clear of debris, it minimizes the cellular blockages that lead to painful breakouts and inflammation.
-
Texture Refinement: Regular use diminishes the appearance of stretched, enlarged pores and smooths out uneven, bumpy skin texture.
Key Ingredients & How They Work
-
Willow Bark Water ($68\%$): Used instead of plain water as the formula’s base. It is a natural anti-inflammatory and soothing agent that calms irritation while naturally prepping the skin for deeper exfoliation.
-
Betaine Salicylate ($4\%$): A gentle yet effective oil-soluble BHA (Beta Hydroxy Acid). Because it is lipid-soluble, it can easily cut through skin oils to exfoliate inside the pore, making it vastly superior to AHAs for blackhead treatment. It is less irritating than pure salicylic acid, making it highly tolerated by sensitive skin.
-
Niacinamide ($2\%$): Works alongside the BHA to brighten the skin, strengthen the natural moisture barrier, control oil, and fade post-inflammatory hyperpigmentation (acne marks).
-
Sodium Hyaluronate: A form of hyaluronic acid that pulls hydration into the skin, preventing the dry, tight, flaky feeling often associated with chemical exfoliants.
Texture & Finish
-
Consistency: A slightly slippery, lightweight fluid that is just a fraction thicker than water.
-
Finish: Spreads easily and absorbs smoothly. It leaves a brief hydrating film upon application that sinks in completely within a minute, leaving no sticky or heavy residue.
-
Scent: Fragrance-free with a very faint, medicinal, clean scent that dissipates instantly upon application.
How to Use
-
When: Best used during your Night (PM) routine after cleansing and toning.
-
Frequency: If you are new to BHAs, start slow by using it 1 to 2 times a week. Once your skin builds tolerance, you can gradually increase usage to every other night or every night depending on your skin’s needs.
-
Application: Pump a small amount onto a cotton pad or directly onto clean hands. Gently swipe or pat over the face, concentrating primarily on congestion-prone areas (like the nose, chin, and forehead), avoiding the delicate eye area.
-
Pro-Tip: Let the liquid sit and absorb for about 2 to 3 minutes before moving on to your next skincare step (like your serum or moisturizer) to let the active BHA work at its optimal pH level. Always apply sunscreen the following morning!
