Hi, I've been using 0.025% Tretinoin for a few months, building up usage gradually up to 3 times per week. I'm using it for any-ageing (in my mid-40s). All going well but I have a few questions and would appreciate advice from seasoned users:
- Should I aim to eventually be using it nightly? If not what's the optimal number of times per week?
- Do I stay on 0.025% or move up to 0.5% when I finish the tube of 0.025%? If I move to the stronger stuff should I go back to starting it once a week and gradually build up again?
- I'm going on holiday to a very hot climate in August. I'll continue to wear 50 SPF daily - is it ok to keep applying the 0.0.25% Retin a at night on hols?
- Any recommendations for an effective AHA toner to get rid of occasional flakiness? I've been using Clarins exfoliating toner a couple of times each week - working well but it's bit pricey so a cheaper but effective alternative would be great! Also any recommendations for a good cheaper facial SPF - I'm using dermalogica which is great but ££.
Thanks for any advice you can share!
