Key Benefits of Stream2Sea Sport Sunscreen SPF 30

 
These are the key benefits you can expect from using Stream2Sea Sport Sunscreen SPF 30:
 

🔵 Lightweight Humectant Moisturizer Ideal for Oily Skin

According to CreamScan analysis, Stream2Sea Sport Sunscreen SPF 30 is quite moisturizing, with a moisturizing rating of 5.0 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 1.6 out of 10 and a very high humectancy of 8.5 out of 10, primarily due to the high content of Camellia Sinensis Leaf Extract (est. ≈6.0%).

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.

🍀 Rich in Skin-Protecting Antioxidants

We estimate that Stream2Sea Sport Sunscreen SPF 30 is rich (> 3%) in antioxidants, specifically Camellia Sinensis Leaf Extract (est. ≈6.0%).

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, Stream2Sea Sport Sunscreen SPF 30 is rich (> 5%) in soothing ingredients, particularly Camellia Sinensis Leaf Extract (est. ≈6.0%) and Ocimum Tenuiflorum Oil (est. ≈4.0%).

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.

☀️☀️ Moderate to High Sun Protection for Daily Outdoor Activities

With an SPF of 30, Stream2Sea Sport Sunscreen SPF 30 provides moderate to high sun protection, making it suitable for daily use during moderate sun exposure, such as commuting or light outdoor activities.

This level of SPF offers excellent defense against UVB rays, blocking up to 97% of harmful radiation. When labeled as broad-spectrum, these products also protect against UVA rays, which are responsible for skin aging and hyperpigmentation.

📌 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.

This level of SPF works well for skin types mildly prone to sunburn. It is particularly suitable for low-to-moderate UV index environments and non-tropical climates. However, it is not recommended for prolonged outdoor exposure or intense UV conditions. Reapplication every two hours is essential 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.

Things to Be Aware Of: Stream2Sea Sport Sunscreen SPF 30

 
CreamScan identified a few things to consider before adding Stream2Sea Sport Sunscreen SPF 30 to your skincare routine:
 

⚠️ Questionable anti-wrinkle efficacy

If one of your main reasons for choosing Stream2Sea Sport Sunscreen SPF 30 is its potential anti-aging effects, please note that, according to CreamScan analysis, it currently has a zero anti-wrinkle rating.

It contains Camellia Sinensis Leaf Extract, an ingredient often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Camellia Sinensis Leaf Extract provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards.

While this does not categorically rule out the possibility that Camellia Sinensis Leaf Extract may reduce wrinkles, its 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, this ingredient does 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.
