Treatments (Face) -COSRX -BHA Blackhead Power Liquid

on 10/23/2018 10:16:00 AM


This product is a great alternative to PC BHA. I used a couple of the other formulations with PC and always found them to be a bit drying. I do not have that problem with this product at all. It is also a 4% concentration. No sting but is certainly effective. I def notice a difference if I stop this product for a while. I also like their AHA product. Great value for your money.

Moisturizers -COSRX -Oil-Free Ultra-Moisturizing Lotion

on 10/18/2018 6:44:00 AM


I had high hopes for this moisturiser, having oily yet dehydrated skin made it sound like the perfect match.

In terms of pro's, I love the consistency when you pump it out and it spreads very easily. It's great value for money, with very hygienic packaging and it's also nice and light so I can imagine it travels well without too much trouble.

However, I will say that I should have taken into account my skin's sensitivity, in terms of fragrance, before buying. The scent, which is not too offensive, in fact it actually smells like Cola, seems to have irritated my skin. Either that or the high concentration of birchsap. Whilst it hasn't made my rosacea worse, it certainly hasn't helped it. The biggest problem I have is that despite it being nowhere near my eyes, it seems to of irritated the hell out of them. Not only slightly itchy but also a slight burning sensation. This could be to do with the lemon peel oil in the ingredients.

I will probably persist with it for a few days as I hate giving up on a product after only a few days in as I would say it leaves my skin sufficiently hydrated and it's such a good price point.

In terms of application I would really recommend patting it in rather than rubbing it, it also seems to work well under makeup. I would also say it does have a slightly sticky feel when first applied.

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

on 10/16/2018 5:25:00 AM


After reading all the reviews here about this I decided to try it as I was at my wits end with the whiteheads that were covering my face. Most pronounced on the T-Zone but pretty much everywhere.

I bought this from Wishtrend and the complimenting BHA Skin Returning moisturiser too. Took about a month to be delivered.

The product stings a little when applied. There was no immediate effect. There was no improvement after 1 month of using every other day. Still no improvement after a month of using every night before bed and still no improvement. I was so frustrated after two months and nothing I was trying would work. My nose was still like a strawberry, my skin in general looked like that too. My skin also became more sensitive and red.

In short it didn't work for me.

However I DID find a real cure :D
Thanks to the great research and reportage by I was able to identify my symptoms and narrow down the possible solutions. I searched for products containing the ingredients he suggested, kept searching for affordable ones, began testing and found a product that worked immediately. Yes immediately! After a few days of use you won't have blackheads either.

I'm delighted to be free of those grim little whiteheads and blackheads. My skin is less irritated and red and pores have shrunk too.

Toners -COSRX -AHA/BHA Clarifying Treatment Toner

on 10/14/2018 10:50:00 PM


I'm a bit of a product junkie, always looking for something better than what I already use, but this is one of the few things I buy well before I run out of it. It's made a huge difference in my oily, mixed acneic skin (whiteheads, cystic acne, you name it, which I finally figured out was both fungal AND bacterial after a bunch of derm consults and trying various things to address both. Oh, and 35 years of acne experience, sadly!). I've also found it to be good at addressing folliculitis on my back which none of the derms could figure out.

Very few ingredients, but highly effective
Alcohol free
Just drying enough on my oily skin
Comes in a spray bottle so I don't waste product and can reach my back
Widely available online
Bottle is a good size and decent price

None that I've found after 4 bottles!
