I am 47, female, fair skin. I feel like I blew it back in 1984 when I was just 20 y.o. & first got a prescription of tretinoin for acne. MDs didn't know to tell patients to wear sunblock back then & I got a deep tan one summer in Spain. The damage is there all these yrs later & the spots tend to come out more when I use Retin A but I don't know anything better for healing the skin. I've used it so long(retin A), feel like it's not as effective: is tazorac stronger? Recommendations?? thank you.
