Formulation: Fermented Ingredients and Key Actives
At the heart of this serum is a blend of fermented ingredients, notably bifida ferment lysate and galactomyces ferment filtrate. These components are widely used in skincare for their potential to support skin texture and hydration.

The full ingredient list is transparently disclosed, which is a notable strength for ingredient-conscious consumers.

What distinguishes this serum in a crowded category is its product-specific clinical backing. According to independent evidence, the serum has been shown to reduce pore area by 30.90% and skin roughness by 11.39% within two weeks of use. These figures are based on clinical testing and provide a rare degree of quantitative support for its claims. The brand further states that pairing the serum with its No.3 toner enhances effectiveness by 214%, though this synergy is specific to the brand’s regimen.
Suitability and Safety Considerations
The serum is positioned as suitable for all skin types, including dry, oily, combination, sensitive, and acne-prone skin. Clinical skin irritation and hypoallergenic tests have been completed, supporting its use for those with more reactive skin profiles.
