Key Benefits of Estelle & Thild Biohydrate Thirst Relief Serum

 
These are the key benefits you can expect from using Estelle & Thild Biohydrate Thirst Relief Serum:
 

🔵 Lightweight Moisturizer Perfect for Combination and Oily Skin

According to CreamScan analysis, Estelle & Thild Biohydrate Thirst Relief Serum is highly moisturizing, with a moisturizing rating of 6.2 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 2.5 out of 10 and a maximum humectancy of 10 out of 10, primarily due to the high content of Aloe Barbadensis Leaf Juice (est. ≈6.0%) and Glycerin (est. ≈4.0%).

This type of moisturizer is ideal for people with combination and oily skin who want maximum hydration in a relatively lightweight, non-greasy formula. It combines a significant amount of humectants with a limited amount of occlusive ingredients to boost moisturizing efficacy without feeling too heavy.

This product may also be a good choice for people with normal skin who prefer fast-absorbing textures, as it balances significant moisturizing potential with a relatively lightweight texture.

💧 A Humectant Boost for Any Skincare Routine

But it’s not limited to combination and oily skin - 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.

🍀 Rich in Skin-Protecting Antioxidants

We estimate that Estelle & Thild Biohydrate Thirst Relief Serum is rich (> 3%) in antioxidants, specifically Aloe Barbadensis Leaf Juice (est. ≈6.0%).

A key benefit of antioxidants is their ability to reduce oxidative stress caused by free radicals and therefore prevent accelerated skin aging. Studies also show that antioxidants can protect against environmental damage such as UV radiation and pollution, and help reduce inflammation and skin redness.

🔴 Skin Soothing and Calming Potential

Based on the ingredient list analysis, Estelle & Thild Biohydrate Thirst Relief Serum is rich (> 5%) in soothing ingredients, particularly Aloe Barbadensis Leaf Juice (est. ≈6.0%).

When applied to the skin, compounds of soothing ingredients, such as triglycerides, phospholipids, fatty acids, phenolic compounds, and antioxidants, work together to soothe the skin through various mechanisms: reducing inflammation, promoting wound healing, repairing the skin barrier, and providing antimicrobial and antioxidant activities.

📌 Please note that this is not a complete list of benefits. We are in the process of enhancing our AI model to incorporate anti-pigmentation, exfoliation and anti-acne ratings.

Things to Be Aware Of: Estelle & Thild Biohydrate Thirst Relief Serum

 
CreamScan AI identified a few things to consider before adding Estelle & Thild Biohydrate Thirst Relief Serum to your skincare routine:
 

⚠️ Questionable anti-wrinkle efficacy

If one of your main reasons for choosing Estelle & Thild Biohydrate Thirst Relief Serum is its potential anti-aging effects, please note that, according to CreamScan analysis, it currently has a zero anti-wrinkle rating.

It contains Gluconolactone, an ingredient often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Gluconolactone provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards.

While this does not categorically rule out the possibility that Gluconolactone may reduce wrinkles, its efficacy is not supported by convincing, vehicle-controlled, double-blind clinical studies - at least none that were available to the CreamScan team at the time of publication.

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.
