Aging is a complex physiological process due to the accumulation of damage over time.

Human skin consists of three layers, namely from surface to depth, the epidermis, dermis and hypodermis. The epidermis is in contact with the outside environment. One of its roles is to protect the body from dehydration and external aggressions, chemical, mechanical or infectious. There is a causal relationship between the intrinsic factors (stress..) or extrinsic (tobacco, infections, certain types of pollution) and skin aging. Pollution is the second skin aging factor after UV radiation.

The balance between the skin barrier and mucous membranes is dependent on complex biological mechanisms involving many growth factors, adhesion molecules, hormones and enzymes. This balance is increasingly compromised with age.

Fighting against skin aging requires a comprehensive response to daily attacks. Effective prevention should have three main components:
- against dryness - against free radicals - provision of micronutrients essential for the elimination of free radicals.

Cosmetics make moisturizers and protective elements essential to the well-being of the skin and maintaining its protective role.

Nutrition, providing additional antioxidants and correcting lack of micronutrients related to age, intervenes in the balance between degradation and repair of the cellular system.

Therefore, LDA Laboratories have chosen for their product range “Soins Experts”, cosmetics and nutritional actives, which are complementary and which reflect the scientific advances regarding of skin aging. .
