Review: COSRX Blackhead Power Liquid (BHA)

This was my first product from COSRX and my first experience into chemical exfoliation.

I use it right after cleansing and using a pH balancing toner (I currently use a simple DIY combo of apple cider vinegar and water) and before AHA, hydrating toners and serums. COSRX Blackhead Power Liquid is oil permeable which means it can get right down into the pores and work it’s gentle exfoliating magic deep in the skin.

I have quite large pores and this is gentle enough to use twice a day for me.

I really like this product a lot – it’s good value for money, and I really admire COSRX as a company for their integrity and dedication.

A while back on the AsianBeauty subreddit there was a discussion on the pH of this product as people with batches made from 2016 onwards were getting higher readings than the expected pH of 3.5-4.5 – most were getting readings of around 5-6.5 – however studies show that Salicylic Acid (and Betaine Salicylate – a neutralised form used in this product) are also effective at higher pHs (6.5). COSRX has responded that the pH had been raised as the previous versions were unstable, and in order to bring the pH back down they would have to add alcohol to the formula.

I find the product still works fine for me – it’s very gentle but I can really see amazing results when I use Fifty Shades of Snail‘s pore shrinking method with my Innisfree Super Volcanic Pore Clay Mask – so I will continue to buy and use this product even with the higher pH.

I would definitely recommend this product to anyone who has enlarged pores, blackheads, or is interested in chemical exfoliation or a K-Beauty style skin care routine.

Love, Selkie.
