COSRX snail products can be bad if you have dust mite allergies, they also badly broke me out.
I adore Curel intensive facial moisteriser. It is an elegant but simple formulation. I personally believe we should use actives to do the work and a good simply moisteriser to... well... moisteriser.
I have been on a very, very long skin journey and my perfected HG routine is.
1st cleanse with cleansing oil, I use Hada Lobo or DH or Laneige or SKIN1004.
2nd cleanse with Curel foaming cleanser.
Then, I do my actives on a rotation of 3.
So, one night I will use tretinoin (I can get mine OTC but if you are in UK I recommend Skin & Me).
Next night I do just cleanse and moisteriser.
The third night, I use Dr. Dennis Gross Intensive peel pads.
These are pricy, but I actually cut mine in half and it is plenty to do a full face. And you really don't need to use them every night to have drastic results.
Nothing else, even Tret, has made such a difference to my fine lines, pigmentation and pores. It is absolutely the one beauty item that I would give up everything else to keep using.
I have tried thousands of pounds worth of products and I currently live in Asia so have access to everything. This routine has made my skin look better than it did 5 years ago.
If you would really like to try out some other products then I can recommend Beauty of Joseon Dynasty Cream, Laneige Cica Sleeping Mask and Laneige Milk Skin Refiner.
