“Nourish the skin and tackle fine lines with Tatcha The Silk Serum, a skincare serum designed to soften visible signs of ageing and improve texture.”
Source: SpaceNK

This product can help improve hydration of the skin with the two types of ingredients.

The first type is called “humectants”:
these ingredients help attract water. When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. The following ingredients in this product do the job: betaine, glycerin.

This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: caprylic/capric triglyceride, helianthus annuus seed oil.

    It didn't cause any reaction in my skin. It smells ok not too strong but a light scent. It feels like water, very runny. I never wore it under makeup so I don't know but for the record it says you can wear it morning/night. I burn like Dracula at dawn so I wasn't taking any chances.
