Scheduling them
- Most nights: DOSE.
- 1–3 nights a week: glycolic acid instead of DOSE.
- Every morning: DOSE and SPF.
Don't over-exfoliate
Too much acid can leave skin tight, shiny and irritated. If that happens, pause acids and let DOSE and moisturiser help your barrier look calmer. See signs of a damaged skin barrier.
