ISOI Blemish Care Up Serum is a vegan hydrating formula designed to support a smooth complexion with a glass-like finish. This 25ml serum combines arbutin, a well-known brightening agent derived from bearberry leaves, with rose otto oil extracted from damask roses. Arbutin helps to visibly reduce the appearance of dark spots and uneven skin tone by inhibiting melanin production, while rose otto oil provides soothing and moisturizing properties that contribute to better skin barrier function and moisture balance.

The lightweight, water-based texture absorbs quickly without leaving a greasy residue, making it suitable for daily use on normal, oily, combination, and sensitive skin types. By reinforcing the skin’s natural barrier, the serum helps maintain optimal hydration levels and protects against environmental stressors. Its cruelty-free, plant-based formulation meets the standards of vegan skincare, appealing to those who prefer clean beauty products without animal-derived ingredients.

Designed for individuals seeking targeted care for blemishes and uneven texture, this Korean skincare product can be incorporated into both morning and evening routines. Apply a few drops after cleansing and toner, gently pressing into the skin for better absorption. The gentle composition makes it appropriate for use alongside other active ingredients, though a patch test is recommended for first-time users with highly reactive skin.

The compact 0.85 fl oz bottle is travel-friendly and allows controlled dispensing. Regular use is intended to gradually refine skin texture and improve overall clarity. With arbutin and rose otto oil as core components, the serum offers a balanced approach to managing imperfections while supporting long-term skin health through barrier support and hydration.
