Key Benefits of ISDIN Nutradeica Seborrheic Skin

These are the key benefits you can expect from using ISDIN Nutradeica Seborrheic Skin:

🔵 Lightweight Purely Humectant Moisturizing, Ideal for Oily Skin

According to CreamScan analysis, ISDIN Nutradeica Seborrheic Skin 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 Acetamide MEA (est. ≈6.8%) and Rhamnose (est. ≈4.6%).

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.

🔴 Skin Soothing and Calming Potential

Based on the ingredient list analysis, ISDIN Nutradeica Seborrheic Skin is rich (> 5%) in soothing ingredients, particularly Stearyl Glycyrrhetinate (est. ≈25.1%) and Zinc Picolinate (est. ≈12.6%).

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

Things to Be Aware Of: ISDIN Nutradeica Seborrheic Skin

CreamScan AI identified a few things to consider before adding ISDIN Nutradeica Seborrheic Skin 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 ISDIN Nutradeica Seborrheic Skin 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.

Pros & Cons of ISDIN Nutradeica Seborrheic Skin

Here’s an overview of the pros and cons of ISDIN Nutradeica Seborrheic Skin to help you decide if it’s the right choice for your skincare routine:

🟩 Pros:

✅ When used alone: Provides humectant-rich moisturizing ideal for oily skin

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

✅ Lightweight texture

✅ Potentially soothing, as it contains a high concentration of soothing ingredients like Stearyl Glycyrrhetinate and Zinc Picolinate

⭕ Cons:

⚠️ Only if used as a standalone moisturizer - it needs to be paired with occlusives to seal in humectants

Summary: ISDIN Nutradeica Seborrheic Skin

Based on the ingredient list analysis, CreamScan AI suggests that ISDIN Nutradeica Seborrheic Skin

, 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.

With a high concentration of soothing ingredients, ISDIN Nutradeica Seborrheic Skin has the potential to calm and comfort irritated skin. 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 ISDIN Nutradeica Seborrheic Skin 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.
