Facial aging is characterised by reabsorption of bone, reabsorption and downward sliding of adipose tissue, reabsorption of collagen (which causes wrinkles) and the appearance of blemishes and fine superficial capillaries. While the volume and descent of the tissues can be corrected with surgery or fillers and botulinum toxin, the more superficial aspect of cutaneous aging can be treated with laser or pulsed light. Pulsed light coagulates fine capillaries and fragments the pigment in blemishes, and over successive treatments the heat it releases also stimulates collagen synthesis which restores luminosity to the skin. Non-ablative rejuvenation is also possible with a non-ablative fractional laser (1540nm wavelength). By this method, which involves a series of treatments, the laser energy alters very thin columns of the dermis which are then substituted by new collagen.
