Based on its formula, is this product safe for sensitive, acne‑prone, or dry skin?

The mask delivers anti‑inflammatory niacinamide and exfoliating salicylic acid, making it well suited for oily or acne‑prone skin, but the presence of denatured alcohol, fragrance and menthol can trigger irritation on very sensitive or dry skin, so a patch test is recommended.

What is the specific role and benefit of niacinamide in this mask?

Niacinamide (vitamin B3) helps to strengthen the skin barrier, reduce excess sebum, fade hyperpigmentation and soothe inflammation, enhancing the mask’s brightening and pore‑refining effects.

What is the optimal application frequency for this mask, and does it contain any controversial chemicals?

For best results, apply the mask once or twice a week, leaving it on 10–15 minutes before rinsing; the formula includes common preservatives phenoxyethanol and ethylhexylglycerin, which are permitted in cosmetics but may be viewed as controversial by some consumers.
