Yes sorry! When I click the reply option it doesn't always seem to make it obvious who I'm replying to.
I had a similar experience of going too strong with an acid and a retinol and really damaged my skin barrier, so I totally get it. Depends on your goals as well (anti-aging versus skin texture). Sounds like you have experience and advice that works for you, and I hope you love the P50 as much as I do (have currently run out, am too broke to replace it and am in mourning for it 🤣).
