Laser treatment involves in using lasers to help in improving the skin concerns. Lasers are wonderful technologies and integral part in our dermatology and cosmetology practice.
Ablative laser is a wounding laser that removes the thin outer layer of skin (epidermis) and heats the underlying skin (dermis), which stimulates the growth of new collagen fibers. Most commonly used ablative lasers are carbon dioxide (CO2) and Erbium laser. CO2 laser resurfacing treatments are used to get rid of scars, warts, and deep wrinkles. Erbium is used for finer lines and wrinkles, along with other superficial skin concerns. Both types of ablative lasers remove superficial layers of the skin. The new skin cells that form after the treatment will be healthier, tighter and free of scars and pigmentation.
Non-ablative lasers don’t remove any skin layers. They only create heat in the skin without injuring the surface of the skin. Most commonly used non-ablative lasers are Pulsed light laser, Q Switched laser and Nd YAG laser. Non-ablative lasers may be used for rosacea, spider veins, and acne pigmentation and also help in skin rejuvenation.
There are no topical creams used. The procedure takes about 15 minutes. There is no downtime associated with Non-ablative lasers.
Topical numbing cream is applied before the procedure. The procedure takes about 30 minutes. The downtime associated with Ablative laser is around 3-9 days.
There are no long-term or unexpected side effects with lasers. Lasers are very precise and easy to handle technologies provided the doctor/the therapist is experienced and the machine is a USFDA approved machine. However, if the treatment is not done well, side effects like burns, PIH and scarring can happen.
