We can treat fine wrinkles using peeling agents. Deep wrinkles can be improved by injecting collagen, or another material that has the same properties, directly into the dermis. Crow's feet and other wrinkles that appear only when you make certain facial expressions can be corrected by botox injection or surgery. There are many non-surgical methods that claim to get rid of acne scars but the result is insignificant improvement. The only way to smooth irregular skin surfaces is to remove the outer surface of the involved area thoroughly and wait for new skin.
Some people use the wrong technique to remove tattoos.
Those techniques usually leave an ugly scar. In some cases, non-physicians simply put a white tattoo on top of the old one. This will make it even more difficult to remove the tattoo later by laser. The correct method is for a doctor to use a laser specifically for removal of tattoos. The Cosmetic Surgery Clinic has this laser.
