Does Saint Jane Beauty Star Flower Hydration Serum with Niacinamide and Hyaluronic Acid work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using Saint Jane Beauty Star Flower Hydration Serum with Niacinamide and Hyaluronic Acid:

  • Significant moisturizing. It has a moisturizing rating of 6.9 out of 10.
  • Little anti-wrinkle effect: Saint Jane Beauty Star Flower Hydration Serum with Niacinamide and Hyaluronic Acid has an anti-wrinkle rating of 0.4 out of 10, so you may expect a positive, although insignificant, effect on wrinkles.

Lightweight moisturizer perfect for oily to normal skin

According to CreamScan analysis, Saint Jane Beauty Star Flower Hydration Serum with Niacinamide and Hyaluronic Acid is highly moisturizing, with a moisturizing rating of 6.9 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 Butylene Glycol (est. ≈4.0%) and Betaine (est. ≈3.0%), and a moderate occlusivity of 3.8 out of 10, mainly due to the high content of Caprylic/Capric Triglyceride (est. ≈6.0%).

This type of moisturizer is ideal for people with oily skin who want maximum hydration in a relatively lightweight, non-greasy formula. It combines a significant amount of humectants with a limited amount of occlusive ingredients to boost moisturizing efficacy without feeling too heavy.

This product may also be a good choice for people with normal skin who prefer fast-absorbing textures, as it balances significant moisturizing potential with a relatively lightweight texture.

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

Little anti-wrinkle efficacy

According to CreamScan analysis, Saint Jane Beauty Star Flower Hydration Serum with Niacinamide and Hyaluronic Acid has a minimal 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, Saint Jane Beauty Star Flower Hydration Serum with Niacinamide and Hyaluronic Acid also contains Beta-Glucan, an ingredient often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Beta-Glucan provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards. Therefore, this ingredient does 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 anti-wrinkle effects through its moisturizing action.

Caprylic/Capric Triglyceride
Est. %6
Function
Origin
