Skin Rejuvenation with Ablative Laser

For patients suffering from facial wrinkles and age spots, laser skin rejuvenation may be a good option for facial rejuvenation. Unfortunately, a single laser does not necessarily solve all problems. There are many different lasers in the market today, and the subject can be very confusing. In addition to the various technologies available, each technology has many brands that claim superiority over others. Laser facial rejuvenation uses ablative lasers and non-ablative lasers.

The two most common technologies for ablation lasers are carbon dioxide lasers and erbium lasers.

Carbon dioxide lasers renew the skin by heating water molecules. The penetration depth of a carbon dioxide laser is approximately 0.2 mm per pass, although heating may occur at a greater depth. Multiple passes can be made with a laser to increase the depth of tissue damage. A carbon dioxide laser removes pigment and wrinkles in two ways. A CO2 laser will remove the outer layer of the skin, the epidermis. This is the layer in which the pigment cells live. The heat of the laser will be transferred to the dermis, which will cause denaturing of the skin’s collagen and the need for its reform. By reforming the collagen and removing some water from the skin, the skin tenses and wrinkles are reduced. Histological studies have shown that CO2 laser treatment is one of three treatments that have scientifically demonstrated an increase in skin collagen. Care must be taken so that the skin is not removed at the level of the dermis, as this can cause scars.

Erbium lasers are also ablative, but not as deep as carbon dioxide. Erbium lasers penetrate approximately 0.05 mm. This means that tissue damage is less, which leads to faster recovery. Unfortunately, since the laser does not penetrate significantly into the epidermis, wrinkle reduction is not so great.

 Conclusion

Even bioflex laser therapy has different delivery systems that can be used. Lasers can be delivered in classic mode, where the entire area is processed, or in fractional mode, where a chess board type template is created. This leaves islands of tissue intact between the treated areas, which provides faster healing of the wound and reduces downtime. Fractional technology has been used with erbium lasers for some time, but only recently has it been applied to carbon dioxide lasers with excellent results.
