What the product description says
“The Dewy Milk Moisturizer”
Source: Tatcha

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: arginine, 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: arginine, bis-diglyceryl polyacyladipate-2.

Chondrus crispus extractKey active· OcclusiveEffect: HighRed algae extract that helps attract water to the upper layer of the skin and create a nicer product consistency~0.45–0.7%
DimethiconeKey active· Emollient, OcclusiveEffect: HighA silicone that helps to reduce water loss from the surface of the skin. Can temporarily "fill in" lines and wrinkles, absorb oil, and create a nice product finish~3.1–3.8%
GlycerinKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~3.9–4.7%
Hydrolyzed sodium hyaluronateKey activeEffect: HighAttracts water into the upper layer of the skin~0.35–0.65%
InositolKey active· HumectantEffect: High~0.5–0.75%
Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.3–0.55%
Solanum lycopersicum seed oilKey active· EmollientEffect: HighA good emollient that helps soften the upper layer of the skin and, due to the high linoleic acid content, can support the skin's barrier function~1.4–1.7%
SqualaneKey active· Emollient, OcclusiveEffect: HighAn oil naturally present in skin. Works as an emollient to soften the skin and form a protective layer on its surface without a greasy feeling.~2.4–2.9%
ArginineKey active· Humectant, OcclusiveEffect: HighAn amino acid that is naturally present in skin and helps keep it hydrated. When used together with AHAs, it can reduce their irritating effect on the skin~0.25–0.45%
Bis-diglyceryl polyacyladipate-2Key active· Emollient, OcclusiveEffect: HighHelps soften the upper layer of the skin and reduce water loss from its surface~1–1.2%
Diisostearyl malateKey active· EmollientEffect: MediumHelps to soften the upper layer of the skin~1.9–2.3%
Saccharomyces/rice ferment filtrateKey active· HumectantEffect: MediumA product of yeast fermentation. Can contain humectants that help attract water to the upper layer of the skin and might help neutralize free oxidants~6.4–7.9%
Tridecyl trimellitate· EmollientEffect: LowUsed to create a thicker product consistency and soften the upper layer of the skin~0.6–0.9%
Pentylene glycol· EmollientEffect: LowUsed to preserve products, dissolve other ingredients and create a nice product texture~0.75–1.1%
Butylene glycol· HumectantEffect: LowUsed to create a nice product texture and help delivery of other ingredients. Might be somewhat helpful in attracting water to the upper layer of the skin~0.25–0.5%
Camellia sinensis leaf extractEffect: LowCan contain potent anti-oxidant compounds (abbreviated ECG, GCG, EGC, and EGCG) that might help protect the skin from free radicals. Can help calm down inflammation and has some anti-bacterial properties. Unfortunately, these antioxidants are unstable and lose their effectiveness very quickly in products. The concentration of the antioxidant compounds in the extract also tends to be low to be effective in topical formulation~0.5–0.7%
GluconolactoneUnder-dosedEffect: HighA polyhydroxy acid (PHA) that helps shed the dead cells from the skin surface revealing smoother skin. Is believed to be genter than AHAs. It helps attract water to the upper layer of the skin and can stimulate production of skin's own hyaluronic acid resulting in improved hydration levels. It has been shown to be helpful against acne and clogged pores if used consistently (e.g over a period of 12 weeks) in high enough concentration. It can help reduce fine lines and wrinkles and improve skin tone with long-term application. Can help neutralize free radicals~0.25–0.5%
TocopherolEffect: Low, below effective dosePure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself~0.3–0.55%
