The four-step routine
Morning: wash with the salicylic acid face wash, apply three to four drops of the 10% niacinamide serum to control oil and calm redness, moisturise lightly, then sunscreen. Night: wash again to remove sunscreen and the day's pollution, apply the 2% salicylic acid serum to clear inside the pores, then moisturise. That is the whole routine. Four products, twice a day, for at least eight weeks before judging it.
Breakouts, purging and when to stop
In the first two to three weeks of salicylic acid, some people see more small pimples in the places they usually break out. That is purging: the acid is bringing congestion that was already in the pore to the surface, and it settles. New breakouts in places you never get them, or burning and persistent redness, are irritation. Drop to twice a week, keep moisturising and build back up.
Do not add a second acid, a scrub or a drying spot treatment on top. More is not faster with acne; it is how the skin barrier breaks down and the cycle restarts.
Acne marks are a separate job
The dark marks that pimples leave behind are pigmentation, not acne, and they respond to a different set of ingredients: niacinamide, vitamin C in the morning and daily sunscreen, which stops the marks darkening further. Picking at pimples is the single biggest cause of marks that stay for months, so the routine above is also the routine that prevents them.
The habits that feed breakouts
Sweat left on the skin after a workout or a ride, a helmet liner that never gets washed, a phone screen pressed to the cheek, and a pillowcase changed once a month all do quiet damage. Rinse or wipe the face after sweating, wash the helmet liner and pillowcase weekly, wipe the phone, and keep hands off the face. Cystic, painful acne along the jaw that does not respond to this routine in three months is worth a dermatologist's visit, not a stronger product.
