What the product description says
“Helps restore skin’s youthful look & delay visible signs of aging”
Source: Tatcha

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains niacinamide.

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: nonapeptide-1.

Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.

NiacinamideKey activeEffect: HighIs proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture. The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production~2.3–2.8%
Nonapeptide-1Key activeEffect: MediumA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~0.25–0.4%
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~0.45–0.7%
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~0.25–0.45%

What the product description says
“Improves moisturization and skin barrier*”
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, betaine.

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, dimethicone.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide, nonapeptide-1

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: niacinamide
