Most conventional cosmetic creams can not achieve skin penetration beyond the outer stratum corneum barrier of the skin, and may only deliver a small percentage of their active ingredients. Defytime Deep Skin Express powered by ActivLayr technology can achieve deep absorption by passing through the stratum corneum into the dermal layer and deliver 100% of the bioactive (TAM CO314818). This intelligent skin delivery system quickly and efficiently carries the actives to where they can live up to their full potential and work within the skin for long term effects.
Human skin anatomy
The thickness of the facial skin varies with age, sex and hereditary. But in general, the full thickness ranges from 0.2 mm to 4 mm (epidermis to hypodermis layer).
The skin consists of three main layers, from the exterior to interior, the epidermis, the dermis and the hypodermis. The epidermis, in turn, is divided in 4 parts, from the inside to the outside, the stratum basale, stratum spinosum, stratum granulosum and stratum corneum which is in contact with the outside [1, 2].
Stratum corneum (SC) is the largest contributor to the barrier function of the skin which prevents large molecules from passing through [2, 3].
