How often should I use it?

Start two or three nights a week and build up only if skin tolerates it. Daily use is too much for many people, especially on dry or sensitive skin.

Can I use it with retinol or vitamin C?

Use it on alternate nights from retinol to avoid over-exfoliating. With vitamin C, separate them into morning and evening routines.

A purge phase is common in the first two to four weeks as clogged pores clear. See a dermatologist if irritation persists beyond that.

It can be, but patch test first and start slowly. The formula is fragrance-free and alcohol-free, which helps, but 2% BHA is still active.

A 30 ml pipette bottle of water-based 2% salicylic acid solution. It contains no fragrance, alcohol or gluten.

No. It is an exfoliating serum, so follow it with a moisturizer to offset dryness.
