I tried Skin & Me and Dermatica when in the UK and I far prefer Skin & Me.
I live in Thailand now, where you can get Tretinoin really cheaply in every pharmacy, so I am quite lucky with that.
(If you know anyone going to a Italy, Spain or Greece on holiday then get them to grab you a few tubes. It's over the counter there too.)
It's really important to protect your skin barrier and start slow.
I started on 0.025% Tretinoin and built up to .1%
I still am cautious as my skin can get irritated, so my routine is this now.
Day 1: Tret
Day 2: Just cleanse, Laneige mist & moisterise
Day 3: Peel pad
Day 4: Just cleanse, Laneige mist & moisterise
Day 5: Tret
Day 6: Just cleanse, Laneige mist & moisterise
Day 7: Peel pad
Day 8: Just cleanse, Laneige mist & moisterise
(You can see the theme. The in-between days are the usual routine + the tret or peel pad.)
The big tubs of Vanicream moisteriser on Amazon are amazing. It has zero irritants in it, so is perfect when using a lot of actives (acids in the peel pads and tret).
The Laneige Cream Skin Cerapeptide Mist is fabulous between cleansing and moisterising (or after the actives) I use it every day.
I double cleanse (oil and then foaming). I'm not fussy about those really, I just make sure there's no irritants or actives in them.
Re cutting the pads in half, I just fold over the top and secure them with a bobby pin.
If you find that you are getting any peeling when you first start tret, this is totally normal, but putting a thin layer of vaseline on after your moisteriser can help lock in hydration. It's called the "slugging method".
