Overnight Exfoliating Treatment — Reddit Reviews
Updated October 13, 2026
Glycolic acid exfoliation for smoother texture; community says gentler than many weekly treatments.
What the community says
An AHA/BHA leave-on treatment used mostly once weekly for texture, sebaceous filaments, and occasional body use. Redditors call it gentler than many weekly treatments, yet tretinoin users skip tret nights and sensitive routines can tip into over-exfoliation.
