Clean & Clear Invisible Blemish Treatment Review

I am 50 now and acne is the last thing that I expect until I was around 45 when I first had rosacea.  The acne also came back soon after.  The condition is not severe to warrant seeing the doctor but with an acne popping up from time to time is not pleasant at all.  I  read that BHA (salicylic acid) may help and I bought this Clean & Clear Invisible Blemish Treatment.  It is a 22 ml tube containing 2 % salicylic acid and costs only a few bucks.  With only one or two acne at a time, the tube will last a long time.  It does help but the effect is not as good as I expect.  It is invisible so it's not obvious after I put it on, but it tends to peel after it dries.  The healing also takes a few days, not fast at all.  When I was young, I used the Clinque Touchstick and it's more effective.  Don't know whether Clinque still carries that product.  Next time I prefer to pay more for better result.
