Hello all....I have hormonal breakouts only on my jaw/neck. A while back I used Differin gel and although it helped some, I had the worst drying-crepey side effects on this area. I had a chicken neck!! Not the effect I was aiming for from a retinoid....I am now considering retinol, retin-a, or Azelex now...any tips or advice on treating this area? I would go back to the Differin if I could just figure out how to make it work on my neck without aging me 20 years.
