Snail Mucin 74% + Niacinamide 5% Dual Face Serum, 2.7 oz | Anti-aging Face Serum for Dull Skin, Sensitive Skin, Korean Skin Care

I have used the normal "Snail Mucin" by Cosrx and I prefer using this one instead, and it has more benefits. It is very lightweight, the bottle size and amount is a lot for the good price, i've had it for a month and still have maybe 75% of the product so this will last me a few months. This is the product I use when I don't have any time to do a full routine, I just use this by itself and go about my day or go to sleep after. It absorbs quickly, gives a nice glow, it is not sticky and it hydrates. Hydrators are water-based and moisturizers are oil-based, I'd say this hydrates my skin but not so much moisturizes. If you have dry skin you may need another moisturizer on top of this, but this is fine for me.

I love this serum! It has a lightweight texture, absorbs quickly, and leaves my skin feeling soft and hydrated. After using it consistently, my skin looks healthier and more radiant. I would definitely buy it again.

I’m 52, post-menopausal, with dry, increasingly sensitive skin, and I’ve used a lot of snail, niacinamide, and “barrier repair” products over the years. Some are fine, many are forgettable. This one genuinely stands out — and now I understand the hype. It’s not hype for the sake of hype; it actually delivers. The dual-chamber design isn’t just a gimmick. It really does let you customize how hydrating versus lightweight you want the application to feel, which makes a noticeable difference depending on how my skin feels that day. I usually mix the two sides evenly, and the texture is beautiful — cushiony and silky with just the right thickness for dry skin, but not sticky, greasy, heavy, or tacky at all. It absorbs quickly and layers easily under moisturizer and sunscreen without leaving residue or pilling. What I noticed most is how calm my skin looks and feels after using this. Redness appears reduced, my skin tone looks more even, and that tired, dehydrated look I sometimes wake up with post-menopause is noticeably improved. With continued use, my skin looks smoother and more rested, especially in areas that tend to show dryness and fine lines. Despite containing niacinamide, this has been extremely well tolerated by my sensitive skin. I experienced no irritation, no tingling, and no flushing, even when my skin was feeling reactive. If anything, my skin feels more comfortable and supported after applying it, which says a lot at this stage. The scent is very subtle and clean — essentially fragrance-free. Nothing perfumey or lingering, and nothing that would bother sensitive skin. Considering how well this works for dry, mature, post-menopausal skin — and how thoughtfully it’s formulated — this is a great value for the price. It delivers real, visible improvement without pushing the skin too hard. This is one of those products that quietly earns a permanent place in your routine. I understand now why people swear by it — because it works. I’m genuinely impressed and will absolutely repurchase.

It doesn't have a strong scent and has contributed to my skin looking healthier, more even, and visibly brighter. After a few months of use and ton of research, I am back with more deets! Having recently incorporated snail mucin and niacinamide into my skincare routine, I’m delighted to share my experience and the remarkable benefits these ingredients offer for the skin. Snail Mucin Pros: Hydration: Snail mucin is incredibly hydrating. It helps to lock in moisture, leaving the skin feeling supple and plump. I noticed a significant improvement in my skin's hydration levels within a few days of use. Healing Properties: This ingredient is known for its healing properties. It has helped to reduce the appearance of acne scars and minor blemishes, promoting faster skin regeneration. Elasticity: Regular use of snail mucin has improved my skin's elasticity. My skin feels firmer and looks more youthful, which is a fantastic benefit for those concerned with aging. Soothing Effect: Snail mucin has a calming effect on irritated skin. It has helped to reduce redness and soothe inflamed areas, making it a great option for those with sensitive skin. Brightening: Over time, my complexion has become brighter and more even-toned. Snail mucin helps to fade hyperpigmentation and improve overall skin tone. Niacinamide Pros: Reduces Inflammation: Niacinamide is excellent at reducing inflammation and redness. It has significantly calmed my skin and reduced the occurrence of breakouts. Minimizes Pores: This ingredient has helped to minimize the appearance of my pores, giving my skin a smoother, more refined look. Oil Control: Niacinamide effectively controls excess oil production. My skin has become less oily throughout the day, which has also helped to reduce acne. Brightening: Similar to snail mucin, niacinamide has brightening properties. It has helped to fade dark spots and even out my skin tone. Anti-Aging: Niacinamide supports the skin's barrier function and enhances its ability to retain moisture, leading to a reduction in the appearance of fine lines and wrinkles. I hope this helps!

Love this product first time you’ve seen this particular one and I love the scent and it goes on smooth and keeps my face moist moisturize

It is a fantastic product for the skin; I feel that my skin looks radiant with continued use.

Was really irritated when I got my bottle and only one side worked. I used scissors to pop the top off and pushed the tabs until the other side worked. Popped the top back on and fixed! I love how this serum makes my skin feel. So soft and moisturizing. Can’t wait to keep using and see the long term benefits.

Three stars because the pump for the snail mucin is messed up. After a long time of messing with it, I was finally able to pop the top off and push down on the little clear part above the snail mucin side. I pushed over and over until it started coming out. Took a while and TBH, this shouldn't even be an issue! I love the product but that needs to be fixed.

So moisturizing so good I like it a lot. I use it as a moisturizer day and night. My skin absorbs it quickly and leaves my face feeling hydrated not sticky. Especially after I use my retinol cream, my face doesn’t feel dry.

Vale, vamos al grano. Llevo un historial de guerra con el acné que ríete tú de los combates épicos de "El Señor de los Anillos". He probado mil potingues, desde mejunjes que huelen a disolvente industrial hasta productos que prometen la piel de un bebé pero te dejan como si hubieras dormido en un parque bajo la lluvia. Spoiler: no funcionan. Así que, en mi desesperación (y con mi cara rogando piedad), decidí darle una oportunidad a este COSRX Niacinamide 5% + Snail Mucin 74% Dual Essence. 🔥 Lo mejor que le ha pasado a mi piel desde que dejé el azúcar (mentira, no lo he dejado) Primero lo primero: ¡La niacinamida! Mi mejor amiga ahora. Lo de "controlar el sebo y calmar la inflamación" no es un mito. En cuanto me lo pongo, noto cómo los granitos que han decidido abrir un Airbnb en mi cara empiezan a cancelar sus reservas. Además, la combinación con la baba de caracol (sí, lo sé, suena asqueroso, pero si funciona, me la unto sin preguntar) es mágica. No solo me calma las rojeces, sino que noto que la textura de mi piel ha mejorado. ¿Efectos secundarios? Ninguno. A no ser que quieras contar como efecto secundario que, ahora que mi piel está más suave, paso demasiado tiempo tocándomela. 🐌✨ Mejor que la esencia sola: lo digo por experiencia Hace tiempo probé la esencia de baba de caracol sola (también de COSRX, porque soy fiel cuando algo no me destroza la cara). Funcionaba bien, no voy a mentir, pero esta combinación con niacinamida... supera todas las expectativas. No solo noto una mejoría en los granitos, sino que la piel apagada y sin vida que tenía antes parece que ha vuelto de unas vacaciones en el Caribe. Conclusión: no vuelvo atrás. Es como comparar una pizza congelada con una recién hecha en horno de piedra. 💀 ¿Oscuridad en mi vida pre-COSRX? No más, gracias Antes de esto, mis días eran una tragedia griega de acné e inflamación. Ahora, no es que mi vida sea un musical de Disney, pero al menos no tengo que batallar contra nuevas colonias de granos cada mañana. Las cicatrices van desapareciendo lentamente, como el ex que te deja de escribir (gracias, universo), y mi piel ya no parece un mapa topográfico. ✨ Espero que esta reseña te haya sido útil ✨ Si tienes alguna duda, déjame un mensaje en el chat del producto, que me encanta hablar de potingues, y no olvides pasarte por mis otras reseñas si quieres más consejitos de belleza con el toque de tragedia griega que caracteriza mi vida. ¡Nos vemos en la sección de "Añadir a la cesta"!

I loved this product Very velvetty texture n non sticky

Très Bon produit

Amazing!! I absolutely love this, I used to buy the moisturiser and snail mucin separately. I love everything from this brand that I have tried. Would highly recommend. Leaves the skin moisturised but not sticky. It is lightweight. Since using COSRX my skin tone, open pores and general appearance has improved(probs been using it for around 6 months now). I have very sensitive skin and it suits me, no irritation. I used it everyday. It is 100/100 on Yuka!!
