Abstract
The use of biomicro-needles, splinters derived from marine and freshwater sponges, is the subject of research worldwide. Their regenerative potential is due to their ability to form microchannels in the skin and persist for 72-120 hours. The study aimed to evaluate the effect of preparation based on biomicro-needles from the Spongilla spicules species on the skin parameters of women with visible signs of ageing. A significant improvement in skin hydration was demonstrated, as evidenced by a decrease in transepidermal water loss, an increase in hydration of the stratum corneum, or a statistically significant decrease in the echogenicity of the dermis. In addition, the thickness of the dermis increased significantly. A decrease in pH, an improvement in barrier function, and a visible reduction in hyperpigmentation,erythema, and wrinkles were demonstrated.
