Dermatologists praise this as a well-formulated, beginner-friendly retinol that pairs retinol with niacinamide to calm redness and support the skin barrier, making it especially suitable for those with rosacea or sensitive skin. The thermal spring water adds soothing minerals and hydration. However, some experts flag the texture as too creamy for a serum, the retinol concentration as low, and the presence of fragrance and denatured alcohol as irritants that may cause sensitivity, particularly with frequent use. Best applied only at night and in small amounts.
