Overview
Exfoliating and toning in one step, this Korean toner uses glycolic acid with niacinamide, betaine, sodium lactate and vitamin C. The title says it can be used day and night and calls out AHA and BHA.
Several actives in one toner, covering exfoliation, tone and vitamin C, make it a compact step for a simple routine. The limitation is that it is scented and acidic, and the listing gives no frequency or sun protection advice.
Who it's for
Someone who wants light daily exfoliation and brightening from a toner will see the use at once. People who already use retinol or other acids, or who avoid scent, should be cautious.
Pros and cons
- Glycolic acid and niacinamide
- Vitamin C among actives
- Day and night use per the title
- Listed for sensitive skin
- Scented, listed as fresh
- No usage frequency listed
- Acids raise sun sensitivity
Performance notes
Glycolic acid loosens surface dead skin so the skin looks smoother, while niacinamide and betaine support tone and hydration. Acid exfoliants raise sun sensitivity, so daytime sunscreen matters. How often to use it depends on how skin reacts, which the listing does not state.
