This retinol ampoule is a Korean-formulated face serum designed for nighttime skincare routines. It contains retinol, a derivative of vitamin A, which is commonly used in skincare to support skin texture and pore appearance. The formula aims to provide pore tightening and refinement benefits, making it suitable for individuals seeking to address enlarged pores or uneven skin surface over consistent use. The product has undergone dermatological testing to assess its compatibility with skin, and it is crafted as a vegan formula, meaning it excludes animal-derived ingredients. Each bottle holds 1.01 fluid ounces of serum, offering a moderate supply for regular application. The ampoule format allows for a concentrated delivery of the active ingredient, which can be integrated into a nightly regimen after cleansing and before moisturizing. Its lightweight texture is designed to absorb without leaving a heavy residue, which may appeal to those with normal, combination, or oily skin types. The retinol concentration is formulated to be effective while aiming to minimize irritation, though individual skin tolerance may vary, and a gradual introduction is often recommended. This product is positioned as a straightforward option for those exploring retinol-based care, focusing on the ingredient’s known properties rather than making exaggerated claims. It does not include artificial fragrances or harsh additives, supporting a gentle approach to nighttime skincare. The Korean skincare tradition emphasizes balanced formulations, and this ampoule reflects that approach with its focus on pore refinement through vitamin A derivatives.
