Laser Medical Beauty Materials

Laser technology has a wide range of applications in the field of medical aesthetics, mainly used for skin aesthetics, hair removal, removal of pigmentation, treatment of vascular lesions and so on. The common materials used for laser aesthetics are Er,Cr,Yb:glass, ruby and Er:YAG, and so on.

Er,Cr,Yb:glass

Er,Cr,Yb:glass is an erbium, chromium and ytterbium doped laser glass material. Due to its unique spectral properties and efficient laser emission, Er,Cr,Yb:Glass has been widely used in the medical and aesthetic fields.

Applications:

Skin rejuvenation and rejuvenation: Er,Cr,Yb:Glass lasers are commonly used for non-invasive skin rejuvenation and rejuvenation. They penetrate the skin precisely, stimulate collagen production and improve the texture and tone of the skin.

Spot and Pigmentation Treatment: Lasers made of this material are effective in destroying hyperpigmentation in the skin and treating a variety of discolorations such as freckles, age spots and sun spots.

Removal of Scars and Stretch Marks: By stimulating the skin’s natural healing process, Er,Cr,Yb:Glass lasers can reduce the visibility of scars and stretch marks.

Ruby

Ruby is a common laser material mainly used to generate red laser light at 694 nm. Ruby lasers also have important applications in medical aesthetics.

Hair Removal: Ruby lasers were one of the first lasers to be used for hair removal, and are particularly suited to hair removal treatments for light colored skin and fine hair.

Removal of tattoos and pigmented spots: The high energy of the ruby laser effectively breaks up pigment particles in the skin for the removal of tattoos and pigmented spots.

Vascular lesion treatment: The laser can also be used to treat some vascular lesions such as dilated capillaries and spider veins.

Er:YAG

The Er:YAG (erbium-doped yttrium aluminum garnet) laser is a solid-state laser with a wavelength of 2940 nm. Due to its close proximity to the absorption peak of water, Er:YAG lasers have strong absorption in tissues with high water content, making them ideal for skin laser treatments.

Applications:

Skin Resurfacing and Resurfacing: Er:YAG lasers are commonly used for resurfacing the epidermis and superficial dermis, removing aged skin cells and promoting the growth of new cells, resulting in smoother, tighter skin.

Scar and Fine Line Removal: Due to its high absorption, Er:YAG lasers are effective in removing fine lines and superficial scars.

Acne Treatment: Er:YAG lasers can deep clean pores, reduce sebum secretion, treat and prevent acne.
