Key Benefits of Aesop Lightweight Facial Hydrating Serum

 
These are the key benefits you can expect from using Aesop Lightweight Facial Hydrating Serum:
 

🔵 Lightweight Purely Humectant Moisturizing, Ideal for Oily Skin

According to CreamScan analysis, Aesop Lightweight Facial Hydrating Serum 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 Aloe Barbadensis Leaf Juice (est. ≈80.0%) and Sorbitol (est. ≈2.0%).

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.

🍀 Rich in Skin-Protecting Antioxidants

We estimate that Aesop Lightweight Facial Hydrating Serum is rich (> 3%) in antioxidants, specifically Aloe Barbadensis Leaf Juice (est. ≈80.0%).

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, Aesop Lightweight Facial Hydrating Serum is rich (> 5%) in soothing ingredients, particularly Aloe Barbadensis Leaf Juice (est. ≈80.0%).

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.

Things to Be Aware Of: Aesop Lightweight Facial Hydrating Serum

 
CreamScan identified a few things to consider before adding Aesop Lightweight Facial Hydrating Serum 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 Aesop Lightweight Facial Hydrating Serum 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.

⚠️ Questionable anti-wrinkle efficacy

If one of your main reasons for choosing Aesop Lightweight Facial Hydrating Serum is its potential anti-aging effects, please note that, according to CreamScan analysis, it currently has a zero anti-wrinkle rating.

It contains Sodium Ascorbyl Phosphate and Camellia Sinensis Leaf Extract, two ingredients often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of these ingredients provide insufficient evidence of efficacy according to CreamScan Research Evaluation Standards.

While this does not categorically rule out the possibility that these ingredients may reduce wrinkles, their efficacy is not supported by convincing, vehicle-controlled, double-blind clinical studies - at least none that were available to the CreamScan team at the time of publication.

Therefore, these ingredients do not generate the anti-wrinkle rating.

📌 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.

Please refer to the Ratings section below for details of the anti-wrinkle rating calculation.

✅ As part of a routine: A humectant moisturizing boost, beneficial for any skin type

✅ Potentially soothing, as it contains a high concentration of soothing ingredients, specifically Aloe Barbadensis Leaf Juice
 

⭕ Cons:

Summary: Aesop Lightweight Facial Hydrating Serum

 
Based on the ingredient list analysis, CreamScan AI suggests that Aesop Lightweight Facial Hydrating Serum
, when used alone, delivers lightweight, humectant-rich moisturizing, making it ideal for oily skin. As part of a moisturizing routine, it provides a humectant boost, beneficial for all skin types.

Whether you’re experiencing redness, irritation, or general sensitivity, its soothing properties may help restore balance and provide relief.
 
That said, there are some things about Aesop Lightweight Facial Hydrating Serum worth noting.
 
Looking at its moisturizing profile, we found that it doesn’t contain any occlusive ingredients, potentially allowing the moisture attracted to the skin by humectants to evaporate. Therefore, if it’s used as the only moisturizer in a routine, it’s recommended to pair it with one that contains at least some occlusive ingredients, such as oils, butters, or silicones.
 
If one of your main reasons for considering Aesop Lightweight Facial Hydrating Serum is its potential anti-aging effects, please note that, according to CreamScan analysis, its anti-wrinkle efficacy is questionable. None of the ingredients in this product provide substantial evidence of their anti-wrinkle efficacy according to CreamScan Research Evaluation Standards.

Est. %4
Function
Origin
PEG-40 Hydrogenated Castor OilA castor oil-derived ingredient often used to incorporate small amounts of oil (such as a fragrance) into a water-based product. PEG-4 HCO is a gold-standard solubilizer and can be used in low amounts due to its ability to solubilize things so well.

Function
Origin
Sodium Ascorbyl PhosphateThe most researched derivative of vitamin C. It boosts collagen synthesis, thereby improving skin structure and elasticity. SAP is effective in the treatment of inflamed acne lesions and has a weak but positive effect on pigmentation issues.
Sodium Dehydroacetate
Est. %0.3
Function

Camellia Sinensis Leaf Extract
Est. %0.3
Function
Origin
