Key Benefits of By Nature Brightening Face Serum with Vitamin C + Collagen

 
These are the key benefits you can expect from using By Nature Brightening Face Serum with Vitamin C + Collagen:
 

Lightweight Purely Humectant Moisturizer Suitable for Oily Skin

According to CreamScan analysis, By Nature Brightening Face Serum with Vitamin C + Collagen is lightly moisturizing, with a moisturizing rating of 3.0 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 moderate humectancy of 5.9 out of 10, primarily due to the high content of Glycerin (est. ≈4.0%).

This product, when used alone as a moisturizer, can provide light humectant hydration in a fast-absorbing formula without any occlusive ingredients. This could work for people with oily skin who need a basic level of hydration.

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 Add-on for Any Skincare Routine

But it’s not limited to oily skin - since it contains a moderate amount of humectants, such a humectant add-on will also positively contribute to the moisturizing efficacy of any skincare routine when used as a step before applying the main moisturizer.

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

Modest Anti-Wrinkle Efficacy

According to CreamScan analysis, By Nature Brightening Face Serum with Vitamin C + Collagen has a modest level of anti-wrinkle efficacy, rated 2.0 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Ascorbyl Tetraisopalmitate (est. ≈1.5%), 
 the only derivative of ascorbic acid with solid evidence of anti-wrinkle efficacy. A single clinical study involving 23 participants (Mariko et al.) demonstrated that a cream with 1% ATIP reduced the average depth of periorbital wrinkles by 6% after 8 weeks of use, compared to a vehicle (the same formulation without ATIP).
 
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.

Things to Be Aware Of: By Nature Brightening Face Serum with Vitamin C + Collagen

 
CreamScan AI identified a few things to consider before adding By Nature Brightening Face Serum with Vitamin C + Collagen to your skincare routine:
 

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 Nature Brightening Face Serum with Vitamin C + Collagen 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.

Pros & Cons of By Nature Brightening Face Serum with Vitamin C + Collagen
