What the community says
Glycolic acid exfoliant favored in the K-beauty community for stopping whiteheads early and refining texture, but can compromise the skin barrier and cause irritation if overused or layered badly.
What people love
- The OG glycolic acid serum without the funky scent of some alternatives
- Stops red, forming whiteheads overnight if caught early
- Often paired with BHA in layered routines for combo skin concerns
Watch out for
- Can cause a burning sensation and barrier fragility, especially on sensitive or dehydrated skin
- Not to be used more than twice a week or alongside retinoids to avoid over-exfoliation
- Users report initial purging and diminishing effects after prolonged use
