What causes aging?

The aging of human skin is affected by numerous factors. As a result of internal and external factors, the skin changes constantly from infancy to adulthood. Structural and functional changes occur within the dermis layer. The dermis layer is the supporting layer and the epidermis is the outer visible layer of skin. The skin’s metabolism and natural functions start declining from the age of 25. Aging means that the cells of our skin are unable to replenish themselves properly and over time the skin’s natural protective external barrier to defend against bacteria is weakened. This results in a dry complexion, wrinkles, sensitive skin, and loss of skin elasticity. After the age of 45, the skin will start to become thinner – making it more vulnerable to damage caused by environmental factors. Research studies, by many experts, and dermatologists indicate that red light emitted by LEDs stimulates and activates the production of collagen and elastin. These are the main proteins that contribute to our skin’s elasticity, texture, and tone.
