Retin A ruined my life, ate up facial fats, left me with blackheads & facial hair. Left side of face is hollow. Can it be fixed?

my Gp prescribed retinA o.05.I applied it to my face every night.4 months Later i notice a significant amount of fat loss but my Gp assured me that retinA wasn't the cause.He advised me to continue using it which i did. But after 2mths my husband told me my eyes looked so hollow;my cheeks that were once chubby were gone. I like sleeping on my left side which sweats a lot.My face looked more slimmer on the left side and i have blackheads and large pores all over. How can i reverse this naturally?
