I’ve done the journey of retinyl palmitate all the way up to 0.025 Tretinoin over 7/8 years and I’m at the point we’re I’ve used that strength of Tret for almost a year and I’m completely tolerant to that strength it’s feels no different on my skin to putting moisturiser on
in a few months I’ll need more Tret but don’t know if I should move up or not, I’m using it purely to keep my skin in decent condition, I’m nearly 50, not for acne etc
