FAQ

Q: I feel a cooling sensation when using this — will it cause irritation?

A: This product has undergone a sensitivity/irritation test for sensitive skin, so it is suitable for sensitive skin use. The cooling sensation you feel is not from an irritating ingredient, but from xylitol, a naturally derived cooling ingredient.

Q: Can this be used both in the morning and at night?

A: Yes, this product can be used both morning and night. Regardless of the ingredients, we recommend using sunscreen alongside it during daytime use for skin protection.

Q: Are there any ingredients to avoid when using this with other products?

A: There are no specific ingredients that need to be avoided when using the Hyaltoin Flooding Serum with other products.

Q: What are the white granules inside the serum?

A: The white granules are ceramide cream that has been formed into small particles and dispersed throughout the serum base. Please note that these are different from encapsulated capsules/beads.

    This serum feels amazing on

    This serum feels amazing on my skin—lightweight, hydrating, and never sticky. I love the cooling sensation when I first apply it, and the little “snowflake” specks dissolve into extra moisture. My skin feels soft, plump, and dewy, and it layers beautifully with the rest of my skincare. A great pick for that glass-skin glow!

    I’ve been loving this Hyaltoin

    I’ve been loving this Hyaltoin Flooding Serum! It’s a total game changer for my dry skin. My face instantly drinks it up without feeling sticky, and also delivers such a cooling feel and sensation. I also love that it’s unscented! My skin has been super dry lately, and this serum’s 11 hyaluronic acids plus glacier water gave me a plump and dewy glow. I also noticed my skin feels less tight and irritated too. A little goes a long way, so the 1oz bottle actually lasts a while. I’ve used it morning and night, and it works just as well solo or under my moisturizer and makeup. Honestly, it’s a great value for how effective it is. Anyone struggling with dry or dry skin would absolutely love this!
