Skin Booster Toner: Skin Boosting Serum with 6 Peptides including Copper Peptides that improve skin elasticity, fine lines, pores, and radiance. Boost your skin’s condition and achieve multiple benefits with this serum.
First Step of Skincare: This lightweight serum with a toner-like texture absorbs quickly into the skin, making it a great first step in your daily skincare routine. Its quick absorption allows for easy layering with other products.
Key Ingredients: 6 Peptides that boost skin elasticity, reduce post hyperpigmentation, control pores, renew skin, calm and alleviate skin, and improve the look of fine lines and wrinkles.
How to Use: After cleansing, apply 2-3 pumps of the Serum on your face. Layer on your favorite moisturizer for additional hydration. Best when used with the COSRX Snail 96 Essence and/or the COSRX Retinol 0.1 Cream.
Customers find the toner serum effective and appreciate its moisturizing properties, with one noting how peptides and niacinamide work together to brighten and even skin tone. Moreover, the product receives positive feedback for its value, being high quality without being overpriced, and customers praise its non-greasy formula that doesn’t leave a sticky residue. However, regarding skin compatibility, while some customers report it doesn’t irritate sensitive skin, others mention experiencing redness and itching. Additionally, the consistency receives mixed reviews, with several customers noting it feels watery rather than like a serum.
