Moisturizers -COSRX -Advanced 96 Snail Mucin Power Essence

on 12/9/2018 8:06:00 PM


I love this product! It recently went up in price on amazon, but none the less it's still not a bad value. I'm still on my first bottle, and I've been using it twice daily for the better part of a year! Once you get past the "ick factor", this is quite hydrating - best applied after toner but before lotions/creams/oils. This makes my skin more radiant, and I have found it heals my post-inflammatory hyper-pigmentation much faster. I haven't had any negative reactions to it - itchiness, dryness, breakouts, etc. I could see this working for every skin type and highly recommend it!

Treatments (Face) -COSRX -AHA 7 Whitehead Power Liquid

on 12/7/2018 5:59:00 AM


I am very happy with this product. I have been using it for 3 months now and have to say that I do see significant improvements in my skin.
My problem areas include: moderate hormonal acne and dull looking skin.

How i use it:
- I apply it in the evening after my (1) oil make-up cleanser, (2) low-ph face wash and (3) ph-correcting toner (research says these steps are critical for getting the Acids to take effect on the skin).
- I opt for patting/dabbing (rather than wiping) on the problem areas.
- I follow this with my hydrating toners, serums and moisturisers (it is known to dry out skin, especially for us combination/dry skin types)

I started using the product very sparingly (once a week) and building it up weekly until i reached the point where i now use it about every second day (4 evenings a week).
After about 4 weeks i started to see a great improvement in my skin's brightness and complexion.
It took about 6 weeks to see significant results with the acne! But it really is working. And works better (for said target areas) than any other product i've tried on the market (although it is my first AHA product and I have never used BHAs).

WARNING: this is a very potent product as it contains active ingredients. My skin is not known to be sensitive and i still purged in the first 2 weeks. I wouldn't recommend it to people with sensitive skin. But for those people whose skin isn't typically sensitive, i'd say be patient until about 2 weeks have passed. If the product still keeps giving problems after that, maybe reconsider? That's what i would have done.

Also the smell is horrid :D. Hence the - 1 point haha.

That said, i think this product caters to a very specific skin market. I think people ought to do a lot of research before simply buying!

Moisturizers -COSRX -Advanced Snail 92 All in One Cream

on 12/5/2018 1:28:00 PM


I never thought anything would unseat Cerave cream as my favorite skincare product of all time, but this amazing little jar of snail goo proved me wrong. I've been using it for two months now and I love it. It's incredibly soothing and it's been so good for my hormonal acne. Even with a gentle, consistent skincare routine and a strict diet, my period always brings a couple of those annoying pimples that never come to a head, and using this cream at night calms them down and shrinks them into invisibility faster than anything else I've ever tried. (And I've tried a lot of things: benzoyl peroxide, niacinamide, panthenol, rosehip oil, various AHAs and BHAs, prescription clindamycin lotion, going fatty alcohol free, going silicone free, going fragrance free, changing pillowcases and wiping down my phone with alcohol daily, blah blah blah.)

COSRX claims this is an "all in one cream." That might be true for people with oily skin, but for me it's not particularly moisturizing so I use it more like a serum. After applying I wait for it to dry down a bit and top it off with a thin layer of Aquaphor. When I wake up in the morning my skin is soft, smooth, and most of all calm and even. It's an absolutely amazing product that I never want to be without again.

Cleansers -COSRX -Low pH Good Morning Gel Cleanser

on 12/1/2018 5:07:00 PM


Was pleasantly surprised by this cleanser! This is perfect for someone who wants a bha face wash, without all the dryness and irritation. This has tea tree oil in it too, which is great for acne prone skin. I was experiencing some mild congestion and hormonal breakouts - this really helped to clear that up. Super gentle, and hydrating too! Twice a week, I take a break from this to prevent the irritation that some people suggest it causes from long term use. But otherwise, this is perfect for combination skin! I am also prone to eczema patches, and this does not cause a flare up at all.

Treatments (Face) -COSRX -Centella Blemish Cream

on 11/25/2018 11:16:00 PM


If you purchase the Cosrx Centella Blemish Cream I highly recommend planing on using this as a spot treatment. The cream is so thick, and loaded with zinc, so it takes forever to absorb. That is also why I recommend using this in the evening because no matter how much you try to massage the cream into skin it still leaves a bit of a white cast. I tried this using it all over my face and I personally think the thickness and consistency of the cream led to me getting a couple breakouts. When I used this as a mere spot treatment I did not have the same issue, thankfully. I know many people like this cream, but I prefer the Cosrx Centella Blemish Ampoule and the Cosrx Centella Alcohol-Free Toner to this cream. I recommend trying these products out first and going to the cream a a last resort.
