Key Benefits of SkinCeuticals Blemish + Age Defense

 
These are the key benefits you can expect from using SkinCeuticals Blemish + Age Defense:
 

Lightweight Purely Humectant Moisturizing, Ideal for Oily Skin

According to CreamScan analysis, SkinCeuticals Blemish + Age Defense 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, entirely due to the high content of Methylpropanediol (est. ≈11.0%).

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.

Slight Anti-Wrinkle Efficacy

According to CreamScan analysis, SkinCeuticals Blemish + Age Defense has a slight anti-wrinkle rating of 1.5 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Glycolic Acid (est. ≈6.0%), 
 a highly effective ingredient in peelings but with moderate anti-wrinkle efficacy in leave-on skincare products, as supported by a single clinical study. This study, involving 72 participants (Thibault et al.), demonstrated that a lotion with 5% GA reduced the fine wrinkling score by 6% after 34 days of use, compared to a vehicle (the same formulation without GA).
 
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: SkinCeuticals Blemish + Age Defense

 
CreamScan AI identified a few things to consider before adding SkinCeuticals Blemish + Age Defense 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 SkinCeuticals Blemish + Age Defense 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

Alcohol Denat.
Est. %50
Function
Origin
Alcohol Denat.

Denatured alcohol is ethanol that contains additives that make it unsafe to consume. It is mainly used as a solvent and an antimicrobial agent. A major drawback to alcohol denat. is that it dries out the skin.

Water
Est. %22
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. %11
Function
Origin
MethylpropanediolMethylpropanediol is a unique glycol that contains two primary hydroxyl groups. That makes methylpropanediol a powerful humectant and an excellent solvent.
Glycolic Acid
Est. %6
Function
Origin
Glycolic Acid

The second most used AHA (after lactic acid) known for its potent exfoliating and smoothing effects. It increases skin cell turnover, which is beneficial for treating acne. When used in peels, glycolic acid has confirmed anti-wrinkle efficacy, though it is less effective in leave-on products like creams and serums.

Origin
Citric AcidA gently exfoliating AHA that helps to remove the top layer of dead skin cells. In comparison to other AHAs, citric acid has been shown to be one of the least effective. It is also very commonly used as a stabilizing and pH-controlling agent.
Capryloyl Salicylic Acid
Est. %0.3
Function
Origin
Capryloyl Salicylic AcidA derivative of salicylic acid, with bigger and more lipid-soluble molecules. This makes it more powerful and safer than salicylic acid. It is used as an exfoliating and peeling agent.
