In line with the concept of demand for healthy, ethical and sustainable products, the company strives for the level of "perfect beauty" by adhering to the program of sustainable development (Sustainable development). Sorghum, the juice of which is part of the Dynalift ™ complex, is part of the sustainable crop development program. Все части растения используются в различных видах промышленности (без растительных отходов) и с применением минимального количества воды.

Ingredients

The complex of plant origin includes the following ingredients (INCI):

  • Water (Aqua)
  • Sodium Polystyrene Sulfonate
  • Sorghum Bicolor Stalk Juice
  • Glycerin

How does this work?

Numerous hydroxyl functional groups –OH of polyosides found in sorghum juice interact with each other and with keratin of corneocytes to form a tightening film on the skin surface. The gravity of each bond creates an immediate, visible and lasting micro-lifting effect.

The microrelief becomes less visible immediately after application and even after 1 hour. Dynalift ™ provides a significant reduction in wrinkles, leaving skin firm and smooth.

  1. Sensory ratings (Eurofins)

The 7% Dynalift ™ Tightening Serum Study was conducted by 15 trained experts and measured results at 5 and 15 minutes, 1 and 2 hours.

During the first hour, most experts noted a strong tightening and film-forming effect, which results in improved skin smoothness and reduction of wrinkles:

The Dynalift ™ complex significantly smoothes the micro and macro relief of the skin. Immediately after application and after 1 hour, the microrelief becomes less visible (after 5 minutes: –55%, after 1 hour: –62%), wrinkles are reduced by more than 23%.

Dynalift™ in L’Adeleide products

“Adelaide” technologists have developed the “Hydrovance with sorghum extract face cream” - a moisturizing and tightening product with the Dynalift ™ complex. Due to the content of the agent Hydrovance®, the cosmetic cream-mask provides long-term hydration and increases the elasticity of the skin, and the active Dynalift ™ complex smoothes micro and macro relief, making the skin elastic, taut, smooth, reducing wrinkles. The cream mask has an unobtrusive, light herbal aroma and a pleasant texture. Free of parabens, mineral oils, synthetic colors and animal products. “Hydrovance with Sorghum Extract” is not tested on animals like all “L'Adeleide” products.
