Treatments (Face) -COSRX -Centella Blemish Cream

on 12/16/2018 3:39:00 PM


Short term, this anti-inflammatory cream works as a spot treatment to make pimples smaller, flatter and less red. The effect is temporary, though, and it does nothing to improve my skin long term. It's handy to have lying around in case of a special event, but I won't miss it when it's gone. It's very thick and leaves a strong white cast which makes it less than ideal under makeup.

Cleansers -COSRX -Low pH Good Morning Gel Cleanser

on 12/16/2018 2:39:00 PM


I have acne along my jawline and chin and i thought it’s most probably hormonal. Switched to this cleanser because there are so many good reviews about it. Used it as a second cleanser after oil cleanser. Significantly reduces acne but does not help with scars from old ones. I think its most probably my old cleanser thats causing the acne (i found out later it contains a few comedogenic ingredients). Packaging is simple and cute but the cover doesn’t really snap shut which makes me wonder if it’s safe for me to put it in a luggage without it spilling everywhere if i ever need to travel.

Moisturizers -COSRX -Advanced 96 Snail Mucin Power Essence

on 12/15/2018 2:50:00 AM


I love this. It's part of my staples. I've been using it since May with great results. I use it after toning with Son&Park beauty water and follow with the Innisfree green tea seed serum. My skin is very oily, sensitive and acne-prone. I'm 34 and live in a tropical island so I spend lots of time in the sun. I have zero age spots and my skin feels like butter, it's the most even and clear it's ever been. It's honestly the best it's ever been, and I think my whole korean routine and more emphasis on hydration had a huge role in that. This product does not have a strong smell, it spreads and absorbs rather quickly it's lightweight and it will not break you out. I thinks it also helps repair the skin barrier, as I grab for this and the Hanskin Real Complexion Hyaluron Skin Essence after using retin -a when my skin gets red and patchy. I will repurchase as there's always a place for an extra layer of moisture in my routine.

Treatments (Face) -COSRX -BHA Blackhead Power Liquid

I was using it for a few months straight only on my nose as that's where I have some blackheads but I didn't notice any difference.

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

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!
