These are the key benefits you can expect from using Teamon Guava Vitamin C Serum:
 

🔵 Slight Moisturizing When Used Alone

According to CreamScan analysis, Teamon Guava Vitamin C Serum is slightly moisturizing, with a moisturizing rating of 1.8 out of 10.

Is it more humectant or occlusive? Question icon The Humectancy (from 0 to 10) is based on the amount of humectants in the formula and indicates how well the product can attract moisture to the skin. Humectants are effective moisturizers that work well for all skin types. The Occlusivity (from 0 to 10) is based on the amount of occlusives in the formula and indicates how effective the product is at sealing moisture into the skin. Occlusive moisturizers are ideal for those with dry skin. Question icon The Humectancy (from 0 to 10) is based on the amount of humectants in the formula and indicates how well the product can attract moisture to the skin. Humectants are effective moisturizers that work well for all skin types. The Occlusivity (from 0 to 10) is based on the amount of occlusives in the formula and indicates how effective the product is at sealing moisture into the skin. Occlusive moisturizers are ideal for those with dry skin. This product has relatively comparable levels of Humectancy and Occlusivity: a low Humectancy of 2.0 out of 10 and a low Occlusivity of 1.6 out of 10.

This type of product provides relatively light moisturizing on its own but can contribute to overall moisturizing efficacy when used as part of a skincare routine, alongside another moisturizer.

Please refer to the Ratings section below for details of the moisturizing rating calculation.

🟣 Modest Anti-Wrinkle Efficacy

According to CreamScan analysis, Teamon Guava Vitamin C Serum has a modest level of anti-wrinkle efficacy, rated 2.5 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Ascorbic Acid (est. ≈10.0%),
 or Vitamin C, a popular ingredient, yet with moderate anti-wrinkle efficacy, as confirmed by a single clinical study involving 20 participants (Humbert et al.). This study showed that a cream with a relatively high concentration of 5% ascorbic acid reduced the average wrinkle depth by 7% after 6 months of use, compared to a vehicle (the same formulation without ascorbic acid).
 
📌 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.

🍀 Rich in Skin-Protecting Antioxidants

We estimate that Teamon Guava Vitamin C Serum is rich (> 3%) in antioxidants, specifically Ascorbic Acid (est. ≈10.0%) and Hyaluronic Acid (est. ≈2.0%).

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, Teamon Guava Vitamin C Serum is rich (> 5%) in soothing ingredients, particularly Cucumis Sativus (Cucumber) Extract (est. ≈75.0%).

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.

Things to Be Aware Of: Teamon Guava Vitamin C Serum

 
CreamScan AI identified a few things to consider before adding Teamon Guava Vitamin C Serum to your skincare routine:
 

⚠️ As a Standalone Moisturizer, It Has Relatively Low Moisturizing Potential

If you use Teamon Guava Vitamin C Serum for moisturizing purposes, please keep in mind that it provides relatively light moisturizing on its own, and, more importantly, it’s not optimal for any skin type.

On one hand, it has low occlusivity, which suits oily and combination skin. On the other hand, it has a low estimated concentration of humectants, which are essential for effective moisturizing of all skin types, including oily skin.

Therefore, if used as a standalone moisturizer, this product should be paired with a humectant-rich moisturizer for optimal skin hydration.

Summary: Teamon Guava Vitamin C Serum

 
Based on the ingredient list analysis, CreamScan AI suggests that Teamon Guava Vitamin C Serum
, as a moisturizer, provides relatively light hydration on its own but can enhance the moisturizing efficacy of any skincare routine.
 
Teamon Guava Vitamin C Serum contains ingredients with proven evidence of anti-wrinkle efficacy that may provide a modest anti-wrinkle effect. As a result, you can expect a positive, though not very significant, impact on wrinkles.
 
Rich in antioxidants, Teamon Guava Vitamin C Serum helps protect against free radical damage and offers multiple benefits for all skin types, including preventing premature aging, defending against environmental damage, and calming inflammation. This product is also formulated with a high concentration of soothing ingredients, offering 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 Teamon Guava Vitamin C Serum worth noting.
 
If you use Teamon Guava Vitamin C Serum as your primary moisturizer, please keep in mind that it provides only light hydration, which isn’t actually ideal for any skin type. While its low occlusivity may work for oily and combination skin, it lacks sufficient humectants, which are vital for effective hydration of any skin type. Therefore, for optimal moisturizing results, it should be paired with a humectant-rich moisturizer.
