COSRX - AHA 7 Whitehead Power Liquid

用後會有刺痛感，但對改善皮膚狀況有明顯效用，會繼續用，希望用後有評論同大家分享

I started with acids for a year ago, Paulas Choice BHA products only. After reading great review cosrx I bought both their BHA and this one. I think the BHA has done most of the job, since it was blackheads I wanted to get rid of. I use this one once a week, just after cleansing. I can really recommend to use a pore mimiaing/clay mask after about 20min after putting on the AHA.

I've only used this a couple of times - I've alternated with the BHA power essence to let my skin adjust - but I can already see a huge difference. My blackheads are smaller (even before using the BHA), not noticed a change in my whiteheads yet, but there is a HUGE change in the smoothness of my skin, it's like my pores have been airbrushed. Recommend using this after toner and then waiting like they say on the bottle - it definitely makes a difference - it then has a chance to penetrate the skin without being diluted by further skincare steps. Oh and also I have a couple of friends who have used it consistently for a while - and they also can't live without it.

Could see the difference in use already after one week of use on the whiteheads on my chin. Blackheads are smaller, skin with sebum deep underneath the surface appears to be more smoothed out. I use it every other day, seems to be a bit strong for everyday use.

After using this, I swear my skin has never felt so smooth and even textured. Of course this doesn't prevent the odd hormonal/diet-induced breakouts, but my skin's overall appearance has improved decently. But ditch those cotton pads, people. Waste of money and bad for the environment. Put a tiny pump into your palm and pat it into your face with your fingers. A little goes a long way!

Never disappointed me, from 1st use 5 years ago to this day. It progressively clears the skin and even your skintone without being harsh on the skin. They recommend to use it only at night but with a good spf I have been able to wear by day - and under makeup. It's not drying but if you have combination skin I recommend to be more generous with your skin in that aspect.

I just purchased my third bottle. I remember going a couple weeks without this and my skin felt so bad without it. I felt like it made my skin soft or something and I felt like this extra step helped exfoliate my skin a little more since it contains aha. I wish they’d make the bottles a little bigger. I can only access cosrx products online since there are rarely any stores in my city that sell Kbeauty products without ripping off the price. it sucks to have to put in an order every couple months but it’s worth it

I've been using this for about 2-3 weeks now and i can say that I've been getting less frequent breakouts especially during that time of the month where my skin goes crazy. It works better than witch hazel, that only did the bare minimum. Some of my whiteheads have been going away and some just seem too stubborn right now. I've experienced some purging like some reviews have said but I suppose that's a good thing as I've read when I looked up on this product. Those breakouts from purging went away after a couple of days with no scarring. I do wish the bottle was a little bigger because I'm almost half way through since I do use it every night and sometimes in the morning. I'd purchase this again though!

The product sits comfortably on skin (not too thick and spreads out easily).I have acne prone skin, with a lot of scarring. I've been using this for 3 weeks and I can see improvements! It doesn't burn my skin (like other products have) and does not feel sticky. Will repurchase!

After struggling with physical exfoliants breaking me out for so long, this is my saving grace. I started off using this once a week, slowly increasing how frequently I used it as time went on and had no problem with irritation, even with my skin being incredibly sensitive. The texture of my skin has been greatly improved so far, as well as my acne and marks left from old acne have both slowly started to fade. I'm looking forward to seeing more improvements with time!

IT HAS HIGHLY HELPED WITH MY ACNE SCARS MORE THAN ANY PRODUCT! Make sure to use my code BEAUTYBYZXF for extra discount at the checkout! <3 PS: I recently became an influencer, your support would mean alot.

Okay, I was hesitant of using aha first because of its photosensitive nature BUT this suprisingly is really mild yet effecting brightening and making my skin tone more even(mind you, I get easily tanned) so a deff pluss! Use code 9PXNHV under friends for extra offer <3

I've been using this product for a few months and I can say there's definitely been a change in my skin texture. My skin is the smoothest it's ever been. You start to see results about 2 weeks in, your skin needs to purge. For me I had some intense dry patches around my mouth, nose and forehead. A few whiteheads but nothing dramatic. I really recommend this if you want a smooth skin texture. (note: if you also want to get rid of blackheads, buy the bha treatment as well. This one doesn't eliminate blackheads)

I use it once a week. I have white heads, blackheads and the structure of my skin is not the best. After using AHA 7%(by the way, the persantage is very good), I can't stop touching my face. It's so smoothe and pleasant to touch. If u have post acne scarring, it may help u with fading it. I will purchase it again after finish. However, it seems like it will last forever haha
