The most common signs of improvements are increased skin elasticity, lifted appearance, reduction of fine lines, improved skin texture, enhanced skin tone, plumper skin, enhanced radiance, increased collagen production, tightened jawline, and neck.

Three related anti-ageing effects.
Each effect targets a different aspect of how skin looks and feels — together they form the core of rejuvenation, firming and lifting claims.
Skin rejuvenating
Skin rejuvenation refers to the restoration and revitalization of the skin's appearance, making it look younger, fresher, and brighter. The primary goals are to improve skin texture, tone, and radiance while reducing the signs of aging.
Skin firming
Skin firming aims to improve the tightness and elasticity of the skin, reducing sagging, and overall firmness.
Skin lifting
Skin lifting involves improving skin sagging and restoring a more lifted appearance. It often targets cheeks, jawline, and neck.
A protocol built for your claims.
Efficacy testing protocol is prepared for each product individually with close cooperation with the sponsor. Based on the claims, usage regime and efficacy expectations, we prepare a protocol that is suitable for the type of product and can confirm product efficacy. The studies can be performed over a different time period (from a few days to several weeks or months) depending on the claim and type of measurement.
