Key ingredients
- Alpha Arbutin — a well‑known pigmentation‑reducing ingredient that supports gradual fading of dark spots with consistent use.
- Niacinamide — multi‑tasking active that balances sebum, improves texture, strengthens barrier, and supports even tone. Independent ingredient analysis notes effective niacinamide levels around 3.8–5.7% for this product, a strong range for anti‑blemish and tone benefits.
- Hydrating support — glycerin, sodium hyaluronate, and calming agents such as allantoin and licorice derivative can bolster hydration and reduce irritation risk; WIMJ highlights this supportive blend in its review.
- Botanical extracts — additional soothing or antioxidant support listed by retailer, contributing to comfort and overall skin health.
