â‹The series âClinical Approach and Procedures in Cosmetic Dermatologyâ intends to be a practical guide in Cosmetic Dermatology.  Procedures in cosmetic dermatology are very popular and useful in medicine, indicated to complement topical and oral treatments not only for photodamaged skin but also for other dermatosis such as acne, rosacea, scars, etc. Also, full-face treatments using peelings, lasers, fillers and toxins are increasingly being used, successfully substituting or postponing the need for plastic surgeries. Altogether, these techniques not only provide immediate results but also help patients to sustain long-term benefits, both preventing/treating dermatological diseases and maintaining a healthy and youthful skin. Throughout this series, different treatments in Cosmetic Dermatology will be discussed in detail covering the use of many pharmacological groups of cosmeceuticals, the new advances in nutraceuticals and emerging technologies and procedures. This volume, entitled âBotulin Toxin, Fillers and Related Substancesâ addresses the most important chemical approaches in cosmetic dermatology. Here are discussed in detail the use of Botulinum toxins and fillers, such as hyaluronic and polilatic acids.
