Key Benefits of Paula's Choice Skin Perfecting 2% BHA Liquid Exfoliant

 
These are the key benefits you can expect from using Paula's Choice Skin Perfecting 2% BHA Liquid Exfoliant:
 

🔵 Lightweight Purely Humectant Moisturizing, Ideal for Oily Skin

According to CreamScan analysis, Paula's Choice Skin Perfecting 2% BHA Liquid Exfoliant 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, due to the high content of Methylpropanediol (est. ≈7.5%) and Butylene Glycol (est. ≈5.0%).

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.

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

Things to Be Aware Of: Paula's Choice Skin Perfecting 2% BHA Liquid Exfoliant

 
CreamScan identified a few things to consider before adding Paula's Choice Skin Perfecting 2% BHA Liquid Exfoliant 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 Paula's Choice Skin Perfecting 2% BHA Liquid Exfoliant 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.

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.
Methylpropanediol
Est. %7.5
Function
Origin
MethylpropanediolMethylpropanediol is a unique glycol that contains two primary hydroxyl groups. That makes methylpropanediol a powerful humectant and an excellent solvent.
Butylene Glycol
Est. %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.

Salicylic Acid
Est. %2
Function
Origin
Salicylic AcidThis effective peeling and anti-inflammatory BHA is used as an anti-acne agent and works by breaking down the junctions between dead skin cells. This results in the peeling of dead skin and the unclogging of pores.
Polysorbate 20
Est. %1.9
Function
Origin
Polysorbate 20A viscous, amber-colored liquid that functions as a solubilizer to disperse small amounts of oil into a large water phase. Polysorbate 20 is frequently used to solubilize fragrance oils into water-based emulsions.
Camellia Oleifera Leaf Extract
Est. %1.8
Function
Origin
Camellia Oleifera Leaf ExtractAn emollient extract derived from the leaves of the Tea-oil Camellia, which is native to Southeast Asia. It contains astringent and wound-healing tannins that create a tightening feeling on the skin and can speed up the healing process of small cuts.
Sodium Hydroxide
Est. %1.5
Function
Origin
Sodium Hydroxide

An ingredient that is able to bring the pH of a product up, thereby making it less harsh on the skin.

Tetrasodium EDTA
Est. %0.3
Function
Origin
Tetrasodium EDTAOne of the most common synthetic chelators. It can reduce the 'hardness' of water and so is often used in rinse-off products.
