How moisturizing is it?

Highly moisturizing: Physicians Formula 24-Karat Gold Collagen Lip Serum has a moisturizing rating of 7.2 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a maximum humectancy of 10 out of 10, primarily due to the substantial concentration of Glycerin (est. ≈6.0%) and Niacinamide (est. ≈4.0%), and a moderate occlusivity of 4.4 out of 10, mainly due to the high content of Sclerocarya Birrea Seed Oil (est. ≈3.0%) and Tocopherol (est. ≈2.0%).

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

Anti-wrinkle efficacy

According to CreamScan analysis, Physicians Formula 24-Karat Gold Collagen Lip Serum has a high anti-wrinkle rating of 6.0 out of 10. It contains one ingredient with proven anti-wrinkle efficacy: Niacinamide (est. ≈4.0%),
 one of the most effective and well-researched anti-wrinkle ingredients.
 
Among others, Physicians Formula 24-Karat Gold Collagen Lip Serum also contains Gluconolactone, an ingredient marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Gluconolactone provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards. Therefore, this ingredient does not contribute to the anti-wrinkle rating.
 

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

Antioxidant benefits

We estimate that Physicians Formula 24-Karat Gold Collagen Lip Serum is rich (> 3%) in antioxidants, specifically Niacinamide (est. ≈4.0%) and Tocopherol (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.
