The reason for the formation of rosacea lies in two points: the expansion of blood capillaries and the skin thinning. Therefore, small blood vessels become visible through the skin.
Accordingly, there are two ways to remove rosacea. One way is to coagulate and contract blood capillaries after absorbing energy by lasers of a certain wavelength. The second way is to stimulate the regeneration of collagen, thickening the thin skin. This can be achieved by laser, intense pulsed light, or by high frequency electromagnetic oscillation.
