Dermatologist - cetaphil, adoxa, differin?

i went to see a dermatologist today about my acne and acne scars, she prescribed me adoxa and differin and also recommended that i used cetaphil, ive used cetaphil in the past and it did not look pretty, i started having cystic acne on my face so i stopped using it, i rebought it today hoping the cetaphil may react differently with the prescriptions, has anyone used this combo before? (cetaphil, adoxa, differin) i would like some input :) also, IF my face does clear from all this, are the results permanent, will i have to keep on with the prescriptions, im not made of moolah :(|||Hey. I actually have used all 3 of those at once and i did see results!!! The cetaphil made my skin feel cleaner and smoother, while the differin mainly dried it out and made my nose peal (Ew).Most notable, were the results from the Adoxa. I know its so expensive, but it works better than anything i%26#039;ve ever used....though, i went off of it for 2 weeks and deffinitely saw acne coming back. The other products helped, but not nearly as much as the adoxa. Hope this helps
