I thought it was a facial Mist but it’s not. It has a squirt top which I love but it’s thicker like a like a phyto-mucin so it fits into the serum part of your routine. I like that it’s scent free for the most part and love how it helps my skin. I give it a 4 and not a 5 mostly bc I didn’t and still don’t entirely understand the product. ### 5.0/5 · Ismam Ahmed Protic · October 10, 2025 Sensitive skin friendly, lightweight, hydrate your skin, fragrance free, good absorption,makes skin softer. Its non comedogenic. But Does give you glass skin but good for skin. ### 5.0/5 · Jalf · October 10, 2025 Desde que mi madre lo probó, no se lo puede quitar de la ducha. Le fascina lo ligero que es, lo rápido que se absorbe, y cómo su piel queda suave, luminosa y con un “efecto jugoso”.Lo mejor: ese cóctel de 6 péptidos + niacinamida + ácido hialurónico que parece realmente actuar, dando firmeza e hidratación sin sensación pesada.Perfecto para mimarte día tras día. ### 5.0/5 · Franco da Silva · October 10, 2025 Me ha sorprendido muchísimo la calidad de este tónico facial. Por el precio que tiene, sinceramente no esperaba que fuera tan bueno. Se nota la diferencia desde las primeras aplicaciones: deja la piel suave, fresca e hidratada sin sensación pegajosa. De verdad, un producto que vale la pena y que sin dudarlo recomendaría. ### 5.0/5 · W L · October 9, 2025 A great overall toner that covers all my needs without any stickiness, leaving my skin with a clean and refreshed appearance.Not overly expensive compared to most toners, and great value for money when on a discount. ### 5.0/5 · SONIA · October 8, 2025 Bien MAIS la marque n'est plus cruelty free depuis octobre. Je ne rachèterai pas. ### 5.0/5 · Katykat · October 4, 2025 C'est mon 2ème flacon et je l'aime beaucoup, texture gel fluide non gras, sans parfum, 6 peptides, absorbé immédiatement par la peau , et il dure longtemps. Un rapport qualité/prix génial. ### 5.0/5 · avis · September 28, 2025 Très bien ### 5.0/5 · Very beautiful · September 19, 2025 Very good ### 5.0/5 · Kelly · September 18, 2025 La texture est tres fluideMais fait son job --- _Source: OpenReviews — https://openreviews.io/en/reviews/cosrx/cosrx-the-6-peptide-skin-booster-serum-8809598455658_
