iS CLINICAL Active Serum is a facial serum formulated to support visible improvements in skin tone evenness while addressing concerns associated with acne-prone and aging skin. The serum combines a stabilized form of vitamin C (L-ascorbic acid) with a retinoid-like compound, Hydroxypinacolone Retinoate (HPR), to offer antioxidant protection and promote cellular turnover without the irritation commonly linked to traditional retinoids. Botanical extracts including cucumber, bearberry, and horsetail are included to soothe the skin and help diminish the appearance of hyperpigmentation over time.

The lightweight, water-based texture absorbs quickly and leaves no greasy residue, making it appropriate for oily, combination, and breakout-prone skin types. It can be incorporated into both morning and evening skincare routines, though consistent daily application with adequate sun protection is recommended when using vitamin C and retinoid derivatives during the day. The formula is free from oil, synthetic dyes, and artificial fragrances, which reduces the likelihood of clogging pores or provoking sensitivity.

This serum is particularly suitable for individuals seeking a multitasking product that addresses uneven complexion, visible signs of aging, and occasional breakouts without requiring multiple separate treatments. The combination of active ingredients aims to support a more balanced, radiant skin appearance when used as part of a regular skincare regimen. The serum is packaged in an opaque, air-restrictive container to preserve ingredient stability and extend shelf life.
