Frequently asked questions
Frequently asked questions
How to use the COSRX The 6 Peptide Skin Booster Serum daily?
Apply a small amount to clean, toned skin, morning and evening. Gently pat until fully absorbed, then follow with your usual moisturizer to lock in the benefits. As with any new skincare product, introduce it gradually into your routine and patch test on a small area before applying it to your face. This peptide-based serumintegrates easily, both morning and evening.
Can the COSRX 6 Peptide serum be combined with exfoliating acids or other active ingredients?
Yes, this serum can be incorporated into a routine containing mild exfoliants or acids like AHAs and BHAs. However, it is best to avoid applying them at the same time to avoid sensitizing the skin: instead, alternate products depending on the time of day or the days of the week. The niacinamideand peptides present in the formula pair well with most simple routines.
How long does it take to see the effects of the COSRX The 6 Peptide Skin Booster Serum?
The available sources do not specify an exact timeframe: results depend greatly on your skin and the consistency of use. The six peptidesand niacinamide work in synergy to support elasticity and even out skin tone over time, but no independent study provides a precise number of weeks. It is best to observe your skin over several weeks of regular use before judging.
What skin types is the COSRX 6 Peptide Skin Booster serum suitable for?
This serum is formulated to be suitable for all skin types, including sensitive skin. Its lightweight, non-sticky texture, based on hyaluronic acidand allantoin, hydrates without leaving a greasy film. It combines hydration, comfort, and gentleness, making it a versatile base for different routines, whether your skin is combination, dry, or prone to tightness.

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.
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.
Recomendado, llegó súper rápido el producto, sin daños, la caja decía frágil, tengo la piel mixta, el producto es ligero sin fragancia, se absorbe rápido, es mi complemento de mi rutina de skincare.
Producto bien embalado, caja sin daños; tardo un poco en llegar pero al final del día si lo hizo
This confuses me but it’s nice. 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.
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.
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.
Bien MAIS la marque n'est plus cruelty free depuis octobre. Je ne rachèterai pas.
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.
Très bien
Very good
La texture est tres fluideMais fait son job
I'm so glad I bought This! It's is just amazing. You notice the difference in the first couple of days and it gets even better
Great product and it give me an amazing result with my face. I would buy it again.
One of my everyday skin routine toners
One of the very good products from Cosrx.Gave me a hydrating effect and niacinamide gave my skin and skin calm. It’s a price to performance product.
I’ve been using the COSRX 6X Peptide Collagen Booster Toner Serum for a few weeks, and I’m impressed! It’s lightweight, absorbs quickly, and leaves my skin feeling hydrated and firm.My skin looks plumper and more youthful, and it’s helped improve my overall texture. Perfect for layering under moisturizer or makeup.Highly recommend if you want a gentle yet effective collagen booster!
This is my 3rd repeat. I love it on my skin. My face looks hydrated and soft
An amazing serum full of various peptites including copper peptides. It's quite a watery consistency but this doesn't stop it being a great product. The amount you get is great and it's easy to use on your face and chest.It's made my skin softer and reduced fine lines slightly. Skin appears more glowy. Skin texture is also better. I used this before applying vitamin c and niacinamide serum, it all absorbed really well.
Excellent rapport qualité prix
Bought this because I had other items from the same line and it’s great. It leaves my skin feeling soft, and if you are someone who used things like retinol it really does help then absorb. I’m in my mid 50s and I’m a complete convert. Moisturiser applied on top also seems to absorb better and, on the rare occasions I actually put makeup on, it sits really well and doesn’t slide or crease. This makes me feel like my skin looks fresher and plumper and my fine lines are gone. Even my 1 deeper forehead crease is barely noticeable.It also causes no irritation.
The COSRX 6X Peptide Collagen Booster Toner Serum has become another standout addition to my daily skincare routine, proving once again why COSRX consistently delivers quality products. I use this as part of a complete COSRX regimen alongside their Advanced Snail Mucin Gel Cleanser and Snail Mucin 96% Power Repairing Essence, and the synergy between these products has resulted in marked improvements in both skin smoothness and hydration levels. What I particularly appreciate about this toner serum is its lightweight, non-sticky formula that absorbs quickly without leaving any greasy residue, making it perfect for layering with other products. The concentrated formula means you only need a small amount per application, which makes this product exceptionally economical and provides excellent value for money. It's become an indispensable part of my skincare routine that seamlessly integrates with other COSRX products for comprehensive skin improvement.Pros:Excellent addition to a complete COSRX skincare routine with proven synergyDelivers noticeable improvements in skin smoothness and hydrationLightweight, non-sticky formula that layers well with other productsQuick-drying without greasy or heavy residueConcentrated formula - a little goes a long way for exceptional valueSeamlessly integrates into daily skincare regimenCost-effective due to small amount needed per applicationConsistent quality from trusted COSRX brandCons:Haven't found any significant drawbacks
I’ve been using the COSRX Peptide Boost Serum as the first step in my routine, and I love how lightweight and refreshing it feels on my skin. It absorbs quickly and gives an instant boost of hydration without feeling sticky or greasy.Over time, I’ve noticed my skin looks a bit firmer and more even-toned. It also helps other products layer beautifully, which makes it a perfect prep step in my skincare routine.I especially love that it doesn’t cause irritation or breakouts, and the formula feels calming even on days when my skin is a little sensitive. Definitely a new staple in my routine!
I use this after cleansing as it apparently helps the efficacy of other serums and toners and gives me a glass effect. It’s super watery but it hydrates the skin quickly and dries quickly as well. I sometimes use this and then put on a peptide face mask for extra peptide goodness. It is quite expensive but I buy it on sale and honestly it seems to go on forever so I do think I get bang for my buck. I have noticed a difference in my skin tone and softness so I will carry one and buy again. As with all these things, long-term use and consistency is key and it may not work for everyone, but I love it’s clean feel and hydration/glass effect.
Conforme à la photo, je recommande.
