Acne vulgaris. This serum is also good?

My acne didnot go away since 3 years even after medication. Acne was like about to go amd return again therefore, my dr. from India prescribed isoretnion 20mg for me once a day. I have been taking it since 2 months and 20 days.From few weeks back I noticed fine lines under and by side of my eyes and also on forehead. I get concerned and visited dr. in Nepal and then dr. over here said that the lines due to isoretnion is due to dryness amd it will not be permanant. However, he mention isoretinion will not going to prevent acne to return. The medication I took were not to stop the acme to return but to stop it for now. In this reagards, he prescribed me other mediaction but I am not having confident to adapt it. What shall I do? Are these medication is right one? Shall I stop isoretinion ?It was prescribed me take for 8 months with regular LFT test in a month. Is this serum is also good? As I also mentioned my hairfall dr. over here prescribed me this serum.
