Before the procedure
- For 2 weeks before the procedure avoid sunbathing, tanning beds and self-tanner.
- For 5–7 days before, pause peels, scrubs, retinoids and acids in the treatment area.
- Tell your specialist about any medication: some antibiotics, isotretinoin and St John’s wort increase sensitivity to light.
- For 2–3 days before — no alcohol and very spicy food.
