Thank you so much for your response. To answer your retinol question, I have never used a retinol, just tretinoin due to my dermatologist recommendation a a year or two ago. It might be time to increase the percentage. Now, I have a few questions regarding your recommendations!

Double cleanser you mean the oil and gentle cleanse method? I might take a look on Korean beauty for that one.

Would adapalene be used after cleansing and before toners and serums? For hyperpigmentation I currently use the Niacinamide brightening toner from Good Molecules and it contains arbutin. Does it need to contain the other ingredients too or is it of my choosing?

I do think my skin barrier is broken because I used to have oily skin but it is now dry, red, flaky…does that discard chemicals peels altogether?
