These consist of salicylic acid, vitamin improvements in lasers that have enabled their A/tretinoin, benzoyl peroxide and antibiotic use in the treatment of skin diseases. For the formulations. In addition, oral antibiotics and most part these have concentrated on non- oral Isotretinoin (Accutane) are also used in the treatment of moderate acne. On average, the rhytides, pigmented lesions, vascular lesions effectiveness of topical or oral medications is technology have resulted in the development of multiple lasers and light sources that are associated with traditional therapies including skin irritation, erythema, chelitis, dry eyes, diseases including Acne Vulgaris (acne). We describe the introduction of a novel dual impressive results in preliminary studies to abnormalities, hypersensitivity reactions, fetal affect the natural course of acne. The evidence to substantiate this is not only a resolution in photosensitivity, irreversible night blindness, the number of papules that were present at the start of treatment, but also a decrease in the formation of new papules. In addition, this technology is fast, has minimal adverse effects acne now go beyond traditional topical and and is associated with zero recovery time.

It is important during treatment thatoptimal contact is made with the skin to deliverthe RF energy and, to deliver the availablefluences of the optical energy safely. The contactcooling handpiece reduces the risk of thermalinjuries to the skin with the short wavelength oflight emitted. Similarly, “arcing” is possible with Figure1.
