Does Tatcha Luminous Deep Hydration Firming Serum work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using Tatcha Luminous Deep Hydration Firming Serum:

  • Strong humectant moisturizing. This lightweight, humectant-rich product, ideal for oily skin, has a moisturizing rating of 5.4 out of 10.

Lightweight moisturizer ideal for oily skin and a humectant boost for any skincare routine

According to CreamScan analysis, Tatcha Luminous Deep Hydration Firming Serum is quite moisturizing, with a moisturizing rating of 5.4 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 0.8 out of 10 and a maximum humectancy of 10 out of 10, primarily due to the high content of Glycerin (est. ≈6.0%), Propanediol (est. ≈4.0%) and Chondrus Crispus Extract (est. ≈3.0%).

This humectant-rich product, when used alone as a moisturizer, is ideal for oily skin, offering significant hydration in a lightweight, fast-absorbing formula with a minimal amount of occlusive ingredients. It’s also a great choice for people with normal skin who prefer lightweight moisturizers.

Such a humectant boost will also positively contribute to the moisturizing efficacy of any skincare routine when used as a step before applying the main moisturizer. This type of formulation is typically used in serums, where a light, fast-absorbing texture is key.

Please refer to the Ratings section below for details of the moisturizing rating calculation.

Questionable anti-wrinkle efficacy

According to CreamScan analysis, Tatcha Luminous Deep Hydration Firming Serum has a zero anti-wrinkle rating.

It contains Camellia Sinensis Leaf Extract, an ingredient often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Camellia Sinensis Leaf Extract provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards. Therefore, this ingredient does not generate the anti-wrinkle rating.

Moisturizers, when used regularly, are proven to prevent wrinkle formation and even reduce existing wrinkles. Therefore, this product, like any other moisturizer, can deliver some anti-wrinkle effects through its moisturizing action.

Please refer to the Ratings section below for details of the anti-wrinkle rating calculation.

Ingredients explained

Water
Est. %75
Function
Origin
WaterThe most used ingredient in skincare. Its concentration defines the product texture: rich creams may have about 50% of water while a light jelly about 90%. Water doesn’t moisturize the skin by itself and is used in skincare as a solvent for other ingredients.
Glycerin
Est. %6
Function
Origin
Glycerin

The most popular moisturizing ingredient in the world. It is a powerful humectant – cheap yet very effective.

Propanediol
Est. %4
Function
Origin
PropanediolAn excellent solvent capable of mixing water with normally water-insoluble ingredients. It also functions as a humectant due to its water-loving alcohol groups. Propanediol can control the viscosity of a product by reducing its thickness.
Chondrus Crispus Extract
Est. %3
Function
Origin
Chondrus Crispus ExtractAn extract from the species of red marine algae called Irish moss or carrageen moss. It is edible and widely used to produce carrageenan, a polysaccharide with humectant moisturizing and soothing properties.
Alcohol
Est. %2
Function
Origin
AlcoholAn effective antimicrobial ingredient that kills bacteria, fungi, and even some viruses. It is also an excellent solvent and astringent. Alcohol helps to create lighter and less viscous products. It can, however, be dehydrating and skin-sensitizing.
Methyl Gluceth-20
Est. %1.5
Function
Origin
Methyl Gluceth-20A humectant synthetically derived from glucose. It takes on the form of a clear, syrupy liquid.

Camellia Sinensis Leaf Extract
Est. %0.3
Function

Est. %0.3
Function
Origin
Sodium Hyaluronate

A sodium salt of famous hyaluronic acid. A potent humectant that hydrates the skin, supports collagen function, and fills out small wrinkles. Sodium hyaluronate also offers soothing and antioxidant properties.
