Key Benefits of One Thing Heartleaf Clear Spot Gel

 
These are the key benefits you can expect from using One Thing Heartleaf Clear Spot Gel:
 

Lightweight Purely Humectant Moisturizing, Ideal for Oily Skin

According to CreamScan analysis, One Thing Heartleaf Clear Spot Gel is quite moisturizing, with a moisturizing rating of 5.0 out of 10.

Is it more humectant or occlusive? It is purely humectant. It has zero occlusivity (we didn't find any occlusive ingredients on the ingredient list) and a maximum humectancy of 10 out of 10, primarily due to the high content of Butylene Glycol (est. ≈7.5%), Polyglycerin-3 (est. ≈5.0%) and Methylpropanediol (est. ≈3.0%).

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.

Things to Be Aware Of: One Thing Heartleaf Clear Spot Gel

 
CreamScan AI identified a few things to consider before adding One Thing Heartleaf Clear Spot Gel 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 One Thing Heartleaf Clear Spot Gel 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.

Function
Origin
Lactobacillus/Houttuynia Cordata Leaf Extract Ferment Filtrate
Butylene Glycol
Est. %7.5
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.

Polyglycerin-3
Est. %5
Function
Origin
Polyglycerin-3
Methylpropanediol
Est. %3
Function
Origin
MethylpropanediolMethylpropanediol is a unique glycol that contains two primary hydroxyl groups. That makes methylpropanediol a powerful humectant and an excellent solvent.
1,2-Hexanediol
Est. %2.5
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
Function
Origin
Glycerin

The most popular moisturizing ingredient in the world. It is a powerful humectant – cheap yet very effective.

Glycereth-26
Est. %1.5
Function
Origin
Glycereth-26

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

Water
Est. %1.3
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.
Tromethamine
Est. %1
Function
Origin
TromethamineAn ingredient based on amino acids that is commonly used as a pH adjuster. It has a high pH, which means that it is basic (alkaline), so adding tromethamine to a skincare product will increase its overall pH level.
Carbomer
Est. %0.3
Function
Origin
CarbomerA synthetic ingredient with the ability to gel water. When used in emulsions, such as lotions and creams, carbomer can also act as an emulsion stabilizer.
Allantoin
Est. %0.3
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.
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.
Ethylhexylglycerin
Est. %0.3
Function
Origin
EthylhexylglycerinA preservative booster derived from glycerin. It is commonly paired with other preservatives to improve their efficacy. Ethylhexylglycerin is also a humectant due to its chemical base of glycerin.
Caramel
Est. %0.3
Function
