  • Transformed my skin to not needing makeup!
I have been self conscious all my life about my skin! Blotchy, red, dry in some spots, oily in other spots, peeling. I would never ever leave the house without makeup! I bought the trial pack of this skincare product which lasted me an ENTIRE MONTH because a little really goes a LOOOOOOONG way and in just a week I already saw a difference! After a month I stopped wearing foundation, concealer, and powder. Then I transitioned to tinted moisturizer. Now only under eye concealer for my genetic dark under eye circles. My skin is plump, looks less old and wrinkly, completely even skin tone! I get so many compliments now on my complexion at 37!!! I have the entire line of this stuff and I love it! ... show more

  • So far so good
I was hesitant to buy this because there are so many products that claim the same results. Still need to evaluate for long term results - but it immediately felt nice going on and my skin did feel less oily yet moisturized from the first day.

First time buying and I would recommend getting it. Does not dry out my skin and leaves my skin feeling refreshing.

  • BHA + Benzoyl Peroxide + AHA = Clear skin (long detailed review)
This may sound strange, but I don't get blackheads. My pores are oily and congested, so most of my breakouts are whiteheads, or just small red bumps near the surface of my skin. So this product wasn't really at the top of my "must try" list. However, after my skin began flaring up this past summer and my usual Acne.org 16 oz. Treatment (2.5% Benzoyl Peroxide) didn't appear to be working on its own, I started doing lots of research on acne products in hopes of finally getting my skin under control. First thing you should know, this product is a chemical exfoliant because it contains beta hydroxy acid (BHA). BHAs are good at getting deep into your pores and clearing out old sebum and dead skin. The most commonly known BHA is salicylic acid, which is found in most North American acne products (and has never worked for me when used on its own). However, instead of being formulated with salicylic acid, the Coxrx Blackhead Power Liquid uses betaine salicylate, which is apparently a gentler BHA and more suitable for sensitive skin. I’ve been using this product every night for the past 8 weeks and I’ve had no issues with it…it goes on easily and doesn’t burn or make my skin feel tight, in fact, it doesn't feel like I have anything on my skin. Lastly, lots of different skincare blogs/message boards agree that after you’ve applied a chemical exfoliant, you should leave it on your skin for at least 20 minutes (or longer) in order to give it time to work on your skin. Apparently this has to do with the various pH levels of skincare products…I’m not an expert, but I’ve been following those general guidelines and leaving the Cosrx Blackhead Power Liquid on my skin for a minimum of 20 minutes before applying anything else and it seems to be working for me. (The wait time is also why I’ve been applying it at night and not in the morning, but you can apply it whenever) The second product I’ve been using in conjunction with Cosrx Blackhead Power Liquid is Acne.org 16 oz. Treatment (2.5% Benzoyl Peroxide). Benzoyl peroxide works by killing acne causing bacteria. I've been using the Acne.org benzyol peroxide gel on and off for years (another well-known brand is Paula’s Choice). The gel has a lower level of benzoyl peroxide (2.5%) which means it is gentle enough to use on a daily basis. Overall it has worked at keeping my acne under control, however, a few months ago it stopped being as effective. I decided to combine the two products together since the BHA’s clean deep within the pores and remove dead skin and sebum, while benzoyl peroxide kills acne causing bacteria. After the first day of trying this routine my acne had already begun to clear up and fade. Within a week my skin was noticeably clearer. After 8 weeks of consistent use my skin is almost totally clear. The biggest change I’ve notice is that my pores are less clogged and congested and do appear smaller. I do occasionally get hormonal acne, but as long as I leave it alone and follow the routine, it clears up quickly. Lastly, about a week ago I began incorporating Alpha Hydrox AHA Enhanced Creme, Anti-Wrinkle Exfoliant - 2 oz to cap off my nighttime routine. Like BHA's, alpha hydroxy acids (AHA's) are chemical exfoliants that exfoliate the upper layers of your skin, which in turn reduces active acne, improves skin texture, and brightens skin. Once I started adding the AHA moisturizer to my nighttime routine my old acne scars began to lighten and fade, and my skin felt smoother. You can totally skip this part and just use a regular moisturizer, but I felt that it took my skin to the next level. So here is a breakdown of the skincare regime I've been using for the past 8 weeks as well as some of the products I have been using: Night 1. Remove makeup. (Bioderma Sensibio H2O Micelle for Sensitive Skin 500 ml.,pack 2). 2. Wash face with a gentle cleanser and warm water. (Cosrx Low Ph Good Morning Gel Cleanser 150ml) 3. Gently pat skin dry with clean towel. Wait a few minutes for skin to get totally dry. 4. Apply the Corsx Blackhead Power Liquid to my skin (I use my fingers to apply). Wait 20-30 minutes to allow it to absorb. 5. Apply Acne.org Benzoyl Peroxide gel to my skin. (The amount you use varies depending on your skin sensitivity. I found that I don't need too much when I use it with the BHA). Wait 5-10 minutes for it to absorb into skin. 6. Apply moisturizer. (Alpha Hydrox AHA Enhanced Creme, Anti-Wrinkle Exfoliant - 2 oz or Olay Complete All Day Moisturizer with Broad Spectrum SPF 15 Sensitive, 6.0 fl oz (Pack of 2)) Morning 1. Cleanse skin with cleanser and warm water. Gently pat skin dry skin with a clean towel. 2. Apply benzoyl peroxide gel as a spot treatment to any active pimples. Wait 5 minutes to allow it to absorb. 3. Apply moisturizer. (Olay Complete All Day Moisturizer With Sunscreen Broad Spectrum SPF 15 - Sensitive, 4 fl. Oz.) 4. Apply Sunscreen. (La Roche-Posay Anthelios 60 Ultra-Light Facial Sunscreen Fluid, Water Resistant with SPF 60, 1.7 Fl. Oz.) A few notes- *If you're going to use any chemical exfoliants (or benzoyl peroxide) you absolutely MUST USE SUNSCREEN EVERYDAY. All of these products make your skin more sensitive to the sun and increase the risk of sunburn! So make sure you're using a good sunscreen. *If you're new to chemical exfoliants start slow. Maybe applying them every other night. My skin can handle nightly use, but proceed with caution. *If you've never used benzoyl peroxide before, start with a very small amount. It can dry your skin out, causing redness and irritation when you first start using it. *DO NOT pick at your skin! I know this is a tough one (especially if you have active acne), but it's important to leave your skin alone. ... show more

  • Finally a pore treatment that actually delivers!
I’ve tried so many "pore-minimizing" products that did nothing but dry out my skin, but this COSRX toner is the real deal. After using it for a few weeks, the pores around my nose and cheeks look significantly smaller and much "cleaner." It’s incredibly effective at clearing out stubborn blackheads without any harsh stinging or irritation. The texture is like water and absorbs instantly, leaving my skin feeling smooth rather than greasy. If you struggle with enlarged pores or an oily T-zone, this is a total game-changer for getting that "filtered" look in real life. Highly recommend! ... show more

  • Great product for reducing pores and smoothing skin
Great product for reducing pores and smoothing skin. Even after 4 months of use (I'm barely half way through the bottle) I'm still seeing results. Initially I had some purging but after about two weeks it quit. How I Use it: I first wash my face with a PH 5.5 cleanser, apply this immediately, let it sit for 20 minutes to let it work. After 20 minutes I don't wash it off, I just apply the rest of my routine. I found not washing it off works best for me. If I apply a vitamin c serum before this, I find it never completely sinks in. If I use this on bare skin, in 20 minutes it will mostly absorb into my skin. Doesn't leave an oily residue or a heavy feeling, just a light layer. When I first started out I only used it every 2 days. After 2 weeks, when the purging stopped, I started using it every other day. After another 2 weeks I started using it everyday. At first I thought it was a "meh" product, but using it consistently is whats making the difference in cleaning out and keeping my pores clean. Its also very gentle, I have eczema and while I did feel a little tingle around my nose, (where its most sensitive), I didn't notice any irritation. After 3 weeks, my skin is smoother than ever, my pores aren't invisible, but much, smaller/cleaner, Pros: Light, easy to use Somewhat gentle Made my skin much smoother Made my skin tone brighter Helped reduce pores Has helped prevent and heal acne Cons: It never completely absorbed, left a slight film on my face ... show more

  • Faulty pump design
The media could not be loaded. The product itself is good, but when you press the pump, it dispenses the product, but also leaks from the pump bottom, down the side of the bottle.. so obviously the product will be used up very quickly.

  • The best thing I’ve ever done for my skin
This is the single most effective treatment I’ve ever used on my skin. I couldn’t believe it. The day I got it, I used it as my nighttime toner, and woke up next morning with noticeably clearer skin and smaller looking pores. I’ve been using it for about two weeks now, and it has made such a huge difference for me. My acne scars have faded a bit, I have no black heads, and the texture of my skin generally looks so much smoother. I didn’t know anything could work this well for my skin. HIGHLY recommend giving it a try ... show more
