How can you safely do a chemical peel at home? A number of at-home chemical peels, masks, exfoliates and wipe products are now available, including those that contain many of the same ingredients as the peels used in doctors’ offices. But it’s key to purchase a quality product, to read ingredients carefully, to test your skin first and to give your skin time to heal between treatments.

In 1465, Sabuncu's book, description, and classification of hypospadias was more informative and up to date. Localization of urethral meatus was described in detail. Sabuncuoglu also detailed the description and classification of ambiguous genitalia.[citation needed] In mid-15th-century Europe, Heinrich von Pfolspeundt described a process "to make a new nose for one who lacks it entirely, and the dogs have devoured it" by removing skin from the back of the arm and suturing it in place. However, because of the dangers associated with surgery in any form, especially that involving the head or face, it was not until the 19th and 20th centuries that such surgery became common.

The first American plastic surgeon was John Peter Mettauer, who, in 1827, performed the first cleft palate operation with instruments that he designed himself. In 1845, Johann Friedrich Dieffenbach wrote a comprehensive text on rhinoplasty, titled Operative Chirurgie, and introduced the concept of reoperation to improve the cosmetic appearance of the reconstructed nose.
Deep chemical peels involve a longer procedure and longer recovery time that lasts up to several months in some cases. Patients who want to correct blotches caused by sun exposure or age, minimize coarse wrinkles, or remove a pre-cancerous growth may benefit from a deep peel. There are certain factors which must be taken into consideration when contemplating a deep chemical peel. Darker-skinned patients and individuals with heart problems are not ideal candidates. Potential chemical peel candidates should be aware that the treatment may take an hour or more, and may require sedation. Anyone who decides on this procedure should be prepared for a long, slow recovery period, and should wear sunscreen whenever exposed to sun.
