[Leong Wai Loon]

Hi Sarah, i found that something is weird. When i apply just a pea size of retin A on face, my face become dry and red and enlarge pores shown. but i apply more my skin feel more supply  and no redness. Is it my skin type is Dry and Sensitive that shown a different reaction?

To be honest, I do not know how this is possible. Normally, the more you apply, the more redness and irritation it causes. Initially, the reaction to Tretinoin can be quite strong but gradually, the skin will get used to Tretinoin.

I cannot comment on your experience because I have no explanation. It would be interesting to hear from other users of Tretinoin.
