CosRX AHA7 Whitehead Power Liquid

A few months into my new skincare routine, I became sensitive to one of my older night creams. (I’m still sad about this. I used to love this cream. I went through a whole process to figure out which product was causing it but that’s a story for a different day). My skin reacted with random closed comedones/whiteheads and bumps on my chin and cheek area. I decided to try the CosRX AHA7 Whitehead Liquid when nothing worked to get rid of them and I hoped this product would. Guess what? It worked wonders!


It’s kind of slimy with a nice amount of slipperyness which means I found it easier to spread over my whole face and didn’t feel like I had to rub it into my skin. It’s a kind of thicker-than-water but still watery liquid that absorbs quite well.


I’ve heard a whole range of odor descriptions for this product and the most common one among them is that it smells like fish. I used to be able to smell it but I really can’t anymore unless I hold it right up against my nostrils and focus on the smell. The smell goes away within a few seconds but luckily I became noseblind to it really quickly. Honestly, the odor isn’t something worth worrying about with this product.


It’s magical! The first time I used it, I saw a HUGE difference in the texture of my skin. After a few more times I had softer skin than ever before – no bumps, no whiteheads, no visible pores and much fewer/lighter spots. Continued usage is necessary to maintain these effects though. You can reduce the number of times you use it to about 2-3 times a week eventually.

Ingredients (From Memebox):

Pyrus Malus (Apple) Fruit Water, Butylene Glycol, Glycolic Acid, Water, Niacinamide, Sodium Hydroxide, 1,2-Hexanediol, Panthenol, Sodium Hyaluronate, Xanthan Gum, Ethyl Hexanediol

Ingredients and purpose (From Jolse):

CosRX creates products with the belief that if they reduce the number of ‘accessory’ ingredients and only focus on the ingredients that have an active, necessary function, they reduce the likelihood of anyone having an unpleasant reaction to the product. This makes sense in theory and I really think it works well in practice too. Out of the 11 ingredients int this product (as far as I can find), only Butylene Glycol has an acne irritant rating of 1 on cosdna. I analyzed Butylene Glycol a tiny bit in my previous post.

The star ingredient of this product is Glycolic Acid, which is the AHA (alpha hydroxy acid) that the name of the product refers to. Glycolic acid is a small molecule that can penetrate the skin layers and loosen upper layers of dry skin. While AHAs don’t clean out pores like BHAs, it is still a good exfoliator. They can lighten dark spots, sun damage spots, hyperpigmentation and acne scars since they ‘peel off’ the upper layers of your dry skin cells to reveal the lower layers.

Important: Don’t forget to use your SPF products when using either AHA or BHA products. While there s still debate on whether AHA is photosensitive or photosensitizing, it’s agreed that exfoliation increases your skin’s vulnerability to sunlight. The dry skin cells act as a layer that blocks at least some of the UV and sun light from reaching the lower layers of your skin. Exfoliation (by acids or mechanical scrubs) takes off these dry layers and exposes the skin to direct sunlight and UV radiation.


This is an irreplaceable product for me. I’ve always had great results with glycolic peels from my dermatologist but found them to be too strong (they sting and dry out my skin for the next few weeks) so I find these to be a great alternative. It’s a slower and much gentler exfoliation treatment and has longer-lasting effects. I recommend this to anyone who has closed comedones, whiteheads and bumps (very vague term but I don’t know how else to describe it) that aren’t rashes. I was convinced to try this product by Fiddy Snails and I’m so glad I listened. Also, CosRX products can be decorated with stickers that are adorable!

Rating: 5/5

  1. Ooh, I have this but haven’t started using it yet. Sounds like I need to. I do sometimes get small bumps (like you said, they’re not zits or rashes, just…bumps). –Angela
