Key Benefits of By Mukk Deep Sea Serum

 
These are the key benefits you can expect from using By Mukk Deep Sea Serum:
 

Lightweight Purely Humectant Moisturizing, Ideal for Oily Skin

According to CreamScan analysis, By Mukk Deep Sea Serum is quite moisturizing, with a moisturizing rating of 4.0 out of 10.

Is it more humectant or occlusive? Purely humectant. It has zero occlusivity (we didn't find any occlusive ingredients on the ingredient list) and a very high humectancy of 8.1 out of 10, primarily due to the high content of Pentylene Glycol (est. ≈3.0%) and Glycerin (est. ≈2.0%).

This humectant-rich product, when used alone as a moisturizer, is ideal for oily skin, providing significant hydration in a lightweight, fast-absorbing formula without any occlusive ingredients.

Tip: Certain studies suggest that humectants alone may not effectively moisturize the skin. If you use this product as your only moisturizer, we recommend following it with one that contains at least some occlusive ingredients.

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.

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: By Mukk Deep Sea Serum

 
CreamScan AI identified a few things to consider before adding By Mukk Deep Sea Serum 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.

If It’s Your Only Moisturizer, It Needs to Be Paired with Some Occlusives

While humectants are highly effective at attracting water to the skin, studies (J. N. Kraft, C. W. Lynde) suggest they may not be efficient when used alone.

One major drawback of purely humectant moisturization is that the water attracted by humectants to the upper layers of the skin can evaporate completely into the environment through transepidermal water loss (TEWL). Adding occlusive ingredients helps seal this moisture into the skin and prevent further water loss.

If you’re using By Mukk Deep Sea Serum as your only moisturizer, consider pairing it with one that contains at least some occlusive ingredients, such as oils, butters, or silicones. These work alongside humectants to create a protective barrier, locking in hydration and ensuring longer-lasting moisturization. The amount of occlusive needed depends on your skin type - the drier the skin, the more occlusives it requires.

If this product is used not as a standalone moisturizer but as part of your skincare routine, such as a toner or serum, it should be applied before your main moisturizer (unless it's a sunscreen), which will provide the necessary occlusivity on top of it.

Questionable anti-wrinkle efficacy

If one of your main reasons for choosing By Mukk Deep Sea Serum is its potential anti-aging effects, please note that, according to CreamScan analysis, it currently has a zero anti-wrinkle rating.

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

While this does not categorically exclude the possibility that Lactobacillus Ferment may reduce wrinkles, its efficacy is not supported by convincing, vehicle-controlled, double-blind clinical studies - at least none that were accessible 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.
