Key Benefits of feelxo: Glacier Niacinamide 5% Serum

 
These are the key benefits you can expect from using feelxo: Glacier Niacinamide 5% Serum:
 

🔵 Lightweight Humectant Moisturizer Ideal for Oily Skin

According to CreamScan analysis, feelxo: Glacier Niacinamide 5% Serum 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 Niacinamide (est. ≈5.0%), Butylene Glycol (est. ≈4.0%) and Glycerin (est. ≈2.0%).

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.

🟣🟣 Significant Anti-Wrinkle Efficacy

According to CreamScan analysis, feelxo: Glacier Niacinamide 5% Serum has a high anti-wrinkle rating of 6.1 out of 10.

It contains 2 active ingredients with proven anti-wrinkle efficacy:

1️⃣ Niacinamide (est. ≈5.0%),
 one of the most effective and well-researched anti-wrinkle ingredients. A clinical study involving 30 participants (Kawada et al.) confirmed that a cream with 4% niacinamide reduced the average depth of wrinkles around the eyes by 9% after 8 weeks of use, compared to a vehicle (the same formulation without niacinamide).
 
2️⃣ Ascorbic Acid (est. ≈0.3%),
 or Vitamin C, a popular ingredient, yet with moderate anti-wrinkle efficacy, as confirmed by a single clinical study involving 20 participants (Humbert et al.). This study showed that a cream with a relatively high concentration of 5% ascorbic acid reduced the average wrinkle depth by 7% after 6 months of use, compared to a vehicle (the same formulation without ascorbic acid).

🍀 Rich in Skin-Protecting Antioxidants

We estimate that feelxo: Glacier Niacinamide 5% Serum is rich (> 3%) in antioxidants, specifically Niacinamide (est. ≈5.0%).

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, feelxo: Glacier Niacinamide 5% Serum is rich (> 5%) in soothing ingredients, particularly Niacinamide (est. ≈5.0%).

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 model to incorporate anti-pigmentation, exfoliation and anti-acne ratings.

Ingredients explained

Water
Est. %80
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.
Niacinamide
Est. %5
Function
Origin
Niacinamide

Also known as vitamin B3, this ingredient is a true superstar with confirmed moisturizing, anti-acne, hyperpigmentation, and antioxidant benefits. Two studies confirm its significant anti-wrinkle efficacy.

Butylene Glycol
Est. %4
Function
Origin
Butylene Glycol

A clear, colorless liquid humectant that draws moisture to the skin. The humectancy of butylene glycol, owed to its two hydroxyl groups, is quite considerable, although not as powerful as glycerin, which contains three hydroxyl groups.

1,2-Hexanediol
Est. %3
Function
Origin
1,2-HexanediolA multi-functional formula helper. It is a well-studied preservtive against bacteria and can help pigments and fragrances disperse evenly in a formula.
Glycerin
Est. %2

Glycereth-26
Est. %1.5
Function

A glycerin-based ingredient with humectant moisturizing properties. It is an excellent emulsifier and thickener.

Xanthan Gum
Est. %1.3
Function
Origin
Xanthan GumA natural multi-functional ingredient that originates from fermented sugars. Xanthan gum acts as a viscosity-building agent to thicken skincare products. It is also an excellent stabilizer and works well to hold other ingredients together.
Allantoin
Est. %1
Function
Origin
AllantoinA fluffy, white powder that acts as a humectant due to its water-loving chemistry and as an exfoliant that helps to remove dead skin cells. It has also been shown to be very soothing to irritated and inflamed skin.
Betaine
Est. %0.3
Function
Origin
BetaineAn ingredient derived from the sucrose in sugar beets. It has a negative chemical charge and a positive chemical charge on the same molecule. This allows betaine to be hygroscopic or humectant and thus provide moisturization by drawing water to the skin.
Panthenol
Est. %0.3
Function
Origin
PanthenolA popular soothing and moisturizing derivative of vitamin B5. Panthenol is particularly beneficial for dry, flaking, burned, or damaged skin. It is used to alleviate the symptoms of a rash, dermatitis, eczema, chapped lips, and sunburn.
Disodium EDTA
Est. %0.3
Function
Origin
Disodium EDTAA synthetic chelator that helps to maintain the look and smell of a product by 'locking up' troublesome metal ions.
Dipotassium Glycyrrhizate
Est. %0.3
Function
Origin
Dipotassium GlycyrrhizateA licorice root derivative with powerful anti-inflammatory and soothing activities. It is often used as a flavoring agent in lip products.
Squalane
Est. %0.3
Function
Origin
SqualaneAn occlusive moisturizing and emollient compound that forms part of the skin’s sebum. The main source of squalane had always been shark liver. Now, however, it is manufactured synthetically or derived from plant oils, such as olive and peanut oil.
Riboflavin
Est. %0.3
Function
Origin
RiboflavinRiboflavin, also known as Vitamin B2, is used in skincare as a coloring agent due to its bright, brilliant orange-yellow color. The research shows that it is a good antioxidant and can protect the skin from UV-induced damage.
Cyanocobalamin
Est. %0.3
Function
Origin
CyanocobalaminA product of bacterial fermentation that may have soothing and rejuvenating skin effects.
Biotin
Est. %0.3
Function
Origin
BiotinBiotin is an important nutrient that can cause weak hair and nails if deficient. Unfortunately, while biotin supplements have promising studies, topical biotin in creams and serums doesn’t have a large body of evidence to support its use.
Ascorbic Acid
Est. %0.3
Function
Origin
Ascorbic Acid

Also known as vitamin C, this multi-benefit ingredient has proven anti-wrinkle, antioxidant, and anti-pigmentation efficacy. It degrades easily when exposed to air and light, so it requires proper packaging to maintain its stability.
