Tretinoin 5

Ive been using Retin-A o.o25% for 11 yrs now and it has worked miracles!!! But recently in the last 4 months i started to get cystic acne around my chin so my doctor prescribed an oral med called monodox and upped my strength in Retin-A to o.1% which is the strongest strength so im worried that my skin will get over dryed or i will break out all over again like i did the first 3 weeks of using the 0.025% 11 years ago. Was wondering if anyone has gone through strength changes and how it has affected you?
