COSRX BHA Blackhead Power Liquid Review+BHA Benefits

Hey everyone! I’m back with another Korean skincare product review. This week’s star is the extremely popular Cosrx BHA Blackhead Power Liquid.

Seem familiar? It’s all over the K-Beauty world right now.


Why BHA?

Before we get into the review itself, let’s go over a few of the benefits of BHA, as well as get rid of some of the common myths that seem to surround this mysterious chemical.

  • BHA stand for Beta Hydroxy Acid. Unlike its water-soluble sister, AHA, BHA is a oil-soluble chemical.
  • The most commonly used BHA in skincare is Salycic Acid, which derives from willow bark
  • BHA does NOT increase sun sensitivity
  • Unlike most claims, Salycic Acid works in a similar way as AHAs do, by thinning the skin layers in order to let out trapped skin cells. The difference? Since Salicylic Acid is oil-soluble, it’s able to penetrate into the oiliest part of you pores


CosRX BHA Blackhead Power Liquid REVIEW:

Ingredients: Salix Alba Bark Water, Butelyne Glycol, Betaine Salicylate, Niacinamide, 1,2 Hexandiol, Arginine, Panthenol, Sodium Hyluronate, Xanthun Gum, Ethyl Hexanediol (CosDNA)

  • Reduce formation of blackheads/excess sebum
  • Hydrate the skin
  • Fade Hyperpigmentation
  • Whiten/Brighten the skin
  • Prevent acne

This product has 4% Salicylic Acid, which is surprisingly high, especially for a Korean brand. Korea has strict regulations on the ingredients that are used in facial products, so BHAs, AHAs, and anything of the like are a relatively new factor in the KBeauty world.

Texture: It has a watery, slightly oil-like feeling. The oily-ish feeling doesn’t bother me too much, and it goes away after applying my ampoules.

Scent: Not a particular smell that I can notice. I’m not terribly sensitive to smells, so if it does have a scent, it doesn’t bother me.

How to Use: BHA is a chemical exfoliant, so like Vitamin C, it works best when the skin is at a low pH. I use a low pH cleanser, which is conveniently also from CosRX, but if not, its best to use a pH-adjusting toner before you use the BHA. But in all honesty, there isn’t any reason why you shouldn’t be using a low-pH cleanser.


I mentioned before in my previous post that the C20 serum is my all-time favorite product, but I think I’ve finally moved on and found a new life-saver. From my first try, I could tell that the Blackhead Power liquid delivered all the things it promised-hyperpgmentation, blackheads, whiteheads, closed comedos, and just the overall texture of my skin. While greatly reduced, I still usually had at least 1 or 2 outbreaks every week when using the C20 serum, but with the BHA liquid, that number’s changed to about 1-2 a month! Another thing I love is how non-irritatable it is to the skin. My skin doesn’t tingle or sting when applying the BHA.

Yet another plus- if you’re on a tight budget, this definetely will work for your skin and you wallet. For around 18 dollars you get 100ml of product. Trust me-this lasts forever. I’ve had mine for about 1 month, and it barely looks like anything’s been tapped out!

Rating(Out of 5): 5. This is my new favorite product that I’ll be shoving into all my acne-prone teenage friends’ faces, and I doubt anything will be able to beat this product for a long time. If you’re struggling with breakouts, this product is a must-have. Even if you’re not, any hyperpigmentation that’s been left from previous acne breakouts will be healed with this as well.

Interested in buying the CosRX BHA Blackhead Power Liquid? It sells for $18.25 at amazon.
