Lasers often produce a faster and more effective result but a period of post-treatment skin recovery is to be expected.
Different types of laser can be used depending on the type of pigmentation - Q-Switched, Pico, Aerolase, Sylfirm, Mosaic, and Thuliam. The non-ablative ones work by breaking down excess melanin so the skin would easily absorb and clear away pigmented areas. As with any treatments, expect minimal side effects such as mild itchiness or a pinkish flush, but this goes away within a few hours. Although you can immediately get back to work, it is best to avoid sun exposure as much as possible.
Intense Pulse Light (IPL) is a well-established means of treating aging skin concerns. IPL is a generic term for any procedure that uses a flash lamp to improve skin appearance. In IPL, light energy of a precise wavelength is absorbed by damaged skin, raising its temperature, and cells respond by producing more collagen. Collagen production softens the appearance of aging skin, fades age spots and pigmentation, improves fine lines and wrinkles, and reduces pore size. Multiple treatments produce the best results after IPL.
Broadband Light (BBL) works by depositing pulses of light energy that gently heats the upper layers of skin. Within the skin, the light energy is absorbed by targets, such as fine, broken vessels that cause redness and brown spots or pigmented lesions that are caused by an overproduction of melanin.
LED (Light Emitting Diodes) light, is not as potent as laser and the results will take months rather than weeks and there will be none of the scarring or downtime that can come from the more aggressive treatments. Red light lies next to infrared at the end of the visible part of the light spectrum, and its wavelengths can help to disable inflammation triggers linked to acne, pigmentation and rosacea. Red light acts as an anti-inflammatory agent, with long enough wavelength to penetrate the epidermis (outermost layer of the skin) and reach the dermis (the middle layer of the skin). This enables it to stimulate fibroblasts (cells that manufacture collagen) and boost skin’s ability to repair and heal. Green LED light though not as documented as red light, can target melanocytes (melanin-producing cells at the bottom of the epidermis) by inhibiting excessive melanin production and breaking up melanin clusters to diminish existing discoloration.
