spot treatment on active white heads

pea sized amount spread evenly on face, I used this very sparsely if I am experiencing dryness/peeling I will skip one night and follow up with it the next

2-3 pumps I actually apply this BEFORE my Twyneo, I used the "sandwich" method per my derm recommendation, where you apply moisturizer then the topical treatment and the moisturizer again to prevent excessive dryness
