How does skin age?

Skin ages just like the rest of the body, but less visibly. This process depends on internal factors (age, genes, hormones) and external- sunlight, smoking or pollution.
Skin ageing leads to dehydration, reduced elasticity and appearance of lines and wrinkles. These changes are the result of reduction in the number of collagen and elastic fibers, synthesized by skin cells . Furthermore, skin texture change, the tan becomes uneven and expanded blood vessels (telangiectasia) appear.

How does intense pulse light (IPL) work?

Pulse rays penetrate the skin, and are selectively captured by melanin (pigment) or oxidised blood in blood vessels. Melanin pigmentation is phisiologically eliminated, and expanded capillaries and blood vessels are narrowed. Meanwhile, fibroblasts are stimulated to produce new elastic and collagen fibers.
