111SKIN Y Theorem Repair Light Serum NAC Y2, 30ml

The 111SKIN Y Theorem Repair Light Serum NAC Y2 is a specialised skincare treatment designed to address multiple concerns associated with oily, combination, and blemish-prone skin types. Its primary function is to deliver a potent blend of active ingredients in a lightweight, fluid formulation that absorbs quickly without leaving a greasy residue or clogging pores. The serum focuses on repairing the skin's barrier, improving tone and texture, and providing long-lasting hydration for a balanced, comfortable complexion. At the core of its formula is the proprietary NAC Y2 complex, developed with insights from space science. This complex combines N-acetylcysteine, Ascorbyl Phosphate, and Aesculus Hippocastum Extract to help maintain optimal levels of collagen and elastin while protecting skin from environmental stressors. Additional key ingredients include Liquorice Root Extract to brighten and even skin tone, Niacinamide (Vitamin B3) to support the skin's lipid barrier and provide soothing benefits, and Calendula for further nourishment and calming properties. The formulation encourages the skin's natural production of Hyaluronic Acid, ensuring deep moisturisation that leaves skin looking plumper and feeling supple. This serum is particularly well-suited for individuals with oily or combination skin who seek effective treatment without heavy textures. It targets unwanted pigmentation, discolouration, and the appearance of acne scarring, while also working to reduce the visibility of fine lines and wrinkles for a more rejuvenated look. Its non-comedogenic properties make it ideal for daily use within a skincare routine, where it can be applied after cleansing and before moisturiser to create a balanced environment for healthier-looking skin.
