Key Benefits of ISOI Skincare Vegan Tone Up Sun SPF 38

 
These are the key benefits you can expect from using ISOI Skincare Vegan Tone Up Sun SPF 38:
 

🔵 Lightweight Humectant Moisturizer Ideal for Oily Skin

According to CreamScan analysis, ISOI Skincare Vegan Tone Up Sun SPF 38 is quite moisturizing, with a moisturizing rating of 5.2 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 1.9 out of 10 and a very high humectancy of 8.6 out of 10, primarily due to the high content of Glycerin (est. ≈4.0%).

This humectant-rich product, when used alone as a moisturizer, is ideal for oily skin, offering significant hydration in a lightweight, fast-absorbing formula with a minimal amount of occlusive ingredients.

It’s also a great choice for people with normal skin who prefer lightweight moisturizers.

💧 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, ISOI Skincare Vegan Tone Up Sun SPF 38 has a slight anti-wrinkle rating of 0.4 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Niacinamide (est. ≈0.3%),
 one of the most effective and well-researched anti-wrinkle ingredients. A clinical study involving 30 participants (Kawada et al.) confirmed that a cream with 4% niacinamide reduced the average depth of wrinkles around the eyes by 9% after 8 weeks of use, compared to a vehicle (the same formulation without niacinamide).
 
Among others, ISOI Skincare Vegan Tone Up Sun SPF 38 also contains contains Camellia Sinensis Leaf Extract and Adenosine, 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 contribute to 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 additional anti-wrinkle effects through its moisturizing action.
 

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

☀️☀️☀️ High Sun Protection for Extended Outdoor Activities and Exposure

With an SPF of 38, ISOI Skincare Vegan Tone Up Sun SPF 38 provides high sun protection, making it ideal for prolonged outdoor activities such as hiking, gardening, sports, or spending time at the beach.

This level of SPF blocks up to 98% of UVB rays, significantly reducing the risk of sunburn. When formulated as broad-spectrum, it also protects against UVA rays, which penetrate deeper into the skin and contribute to premature aging, hyperpigmentation, and long-term damage.

This level of SPF is recommended for most skin types, including those with moderate sun sensitivity. For individuals with fair or very sensitive skin, or under intense sun exposure, a higher SPF of 50+ is advised.

📌 For optimal protection, choose products labeled broad-spectrum to ensure defense against both UVA rays, which contribute to skin aging and pigmentation, and UVB rays that cause sunburn.

It's important to apply sunscreen generously and reapply every two hours or after swimming or sweating to maintain effectiveness.

📌 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.
