Acne vulgaris. Is also safe to use?

As my acne was didnot go away since 2.5 years even after medication therefore, my dr. from India prescrined isoretinion 20 mg once since two months and 20 days.  My face is too dry now and fine lines have developed under my eyes and on my forehead which was not there before a month.I have been applying cetaphil hydrating cream too but still my fave get dry and helping lines to be viaible. I was and am worried if isoretnion causes fine lines of aging So, I visited dr.here in Nepal and he prescribed me these stuffs and suggest me to stop isoretinion not because of development of fine lines but by saying it will not stop the acne to return. However, he also mention the fine lines caused by isoretinion is not peramanant and will go after the completion of dose. I need help to know if these new suggested stuffs are really right one ? Is that hair serum is also safe to use? Thanking you with greetings.
