For serious skin rejuvenation, an individual should pay a visit to his/her health care professional. The doctor can provide treatments that go below the surface layer and provide longer-lasting results. For example, a simple treatment of alphahydroxy acid only takes about 15 minutes. The patient can immediately return to work, and the dry upper layer of skin has been removed, leaving the new, fresh layer of skin that was once beneath the surface. For a complete rejuvenation that last a long time, a person should consult the doctor regarding phenol treatments. The chemical peel is so strong it can remove multiple layers of skin, smooth out deep acne scars and wrinkles, while rejuvenating the skin to look younger and healthier. However, it will be important after skin rejuvenation treatment to follow the doctor's directions and use sunscreen with a SPF of at least 30.
