You have to be very, very careful of your skin barrier.
This was my routine for 2 months.
Then I moved to one day on/one day off for actives.
Day 1 - Peel Pad/acid
Day 2 - No Actives
Day 3 - No Actives
Day 4 - Tret
Day 5 - No Actives
Day 6 - No Actives
Day 7 - Peel Pad/Acid
Day 8 - No Actives
Day 9 - No Actives
Day 10 - Tret
Day 11 - No Actives
Day 12 - No Actives
Day 13 - Peel Pad/Acids
Day 14 - No Actives
Day 15 - No Actives
I find that if I don't use any acids then I do get a bit of dullness and clogged pores still, even though the tret does help with that.
Many dermatologists say it is absolutely fine to use both as long as you start slow and listen to your skin. Peeling is normal when beginning tret, but if you are peeling then lay off the acids. Any burning or excessive redness, take a break etc.
Most people I know use both successfully, it just depends on the individual how long it takes to build them into regular use.
I have to do one day on and one day off or my skin gets irritated.
It's important to also be aware of fragrance and other irritants.
Vanicream is the best moisteriser I've found paired with actives.
I also double cleanse but I made sure my cleansers have no acids or things like it vit C.
I look for the words hydrating and soothing.
I used to really struggle with adult acne and huge pores, but my skin is clear, has a glow and is much more refined now. Unfortunately if I stop the peel pads then I notice within about a week 😭
