Key Benefits of facetheory Regenacalm 2% Retinol and Vitamin C Serum S1

 
These are the key benefits you can expect from using facetheory Regenacalm 2% Retinol and Vitamin C Serum S1:
 

🔵 Lightweight Humectant Moisturizer Ideal for Oily Skin

According to CreamScan analysis, facetheory Regenacalm 2% Retinol and Vitamin C Serum S1 is quite moisturizing, with a moisturizing rating of 5.1 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 0.2 out of 10 and a maximum humectancy of 10 out of 10, primarily due to the high content of Propanediol (est. ≈6.0%) and Glycerin (est. ≈4.0%).

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.

💧 A Humectant Boost for Any Skincare Routine

But it’s not limited to 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.

Things to Be Aware Of: facetheory Regenacalm 2% Retinol and Vitamin C Serum S1

 
CreamScan AI identified a few things to consider before adding facetheory Regenacalm 2% Retinol and Vitamin C Serum S1 to your skincare routine:
 

⚠️ If It’s an Exfoliator, It May Increase Skin Photosensitivity Due to Lactic Acid

This product contains lactic acid, a popular AHA known for its ability to gently exfoliate and brighten the skin. It works by removing dead skin cells, revealing new, more delicate skin that is more vulnerable to sun damage.

In smaller quantities, lactic acid is often used as a pH adjuster and may not significantly contribute to exfoliation. However, at higher concentrations, it functions as an effective exfoliant with benefits and risks similar to other AHAs. Products with AHAs, including lactic acid, may increase skin sensitivity, making it more prone to sunburn or irritation when exposed to UV rays.

If this product is designed for exfoliation, applying a broad-spectrum sunscreen with at least SPF 30 daily is essential to protect your skin. Always check the label or the manufacturer’s website for specific usage instructions.

⚠️ Questionable anti-wrinkle efficacy

If one of your main reasons for choosing facetheory Regenacalm 2% Retinol and Vitamin C Serum S1 is its potential anti-aging effects, please note that, according to CreamScan analysis, it currently has a zero anti-wrinkle rating.

It contains Retinyl Palmitate and Sodium Ascorbyl Phosphate, two ingredients often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of these ingredients provide insufficient evidence of efficacy according to CreamScan Research Evaluation Standards.

While this does not categorically rule out the possibility that these ingredients may reduce wrinkles, their 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, these ingredients do 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.
