Photo rejuvenation involves using an energy-delivery device to improve skin texture, fine wrinkles, scars, and hyper pigmentation (skin discoloration such as sun spots, age spots, and freckles). Photo rejuvenation falls into three categories: mechanical, thermal, and chemical. Mechanical methods include lasers, thermal include Thermage, and chemical includes chemical peels.
Photo rejuvenation technology is always changing and improving. Some of the most common problems of sun damaged and aging skin which can be treated with photo rejuvenation are:
Photo-Aging, Hyperpigmentation, and Large Pores: Intense pulsed light (IPL) systems have proven useful for sun damage, hyperpigmentation, and large pores.
Skin Irregularities, Fine Lines, and Dark Skin Discoloration: CO2, erbium/YAG, and combination CO2-erbium/YAG lasers have been beneficial for skin irregularities, wrinkles, acne scars, and certain types of skin discoloration.
Sun Damage: Pulsed dye lasers or IPL are used for sun damage and aging skin.
Melasma: Kligman’s formula followed by frequency-doubled Q-switched laser or IPL has been effective for the management of melasma, a patchy or generalized dark or tan discoloration of the skin.
Pigmented Lesions: A combination of a frequency-doubled Q-switched Nd:YAG (KTP) laser and also an IPL is useful for pigmented lesions. However, laser treatment is not recommended for removal of dark moles.
Wrinkles and Sagging Skin: For different signs of aging, such as droopiness of the tissues, loss of volume, and loss of elasticity, and surface discoloration, one can opt for various treatments like dermabrasion, chemical peel and laser resurfacing, infrared light, low-level laser, IPL, and even radio-frequency devices.
IPL therapy does help in collagen and elastic fiber production. Collagen supports fibroblasts, which act as bridges of support for the skin just below the skin surface. Collagen production decreases with age, so the stimulation of collagen production through light therapy or lasers can help reduce the effects of aging on the skin.
Scars: Keloid and hypertrophic scars respond to 585-nm pulsed dye laser (PDL) treatments. Raised scar edges may require an additional laser such as the Er:YAG or CO2 laser system.
