Botox. Botox is probably the most well-known noninvasive anti-aging technique, including a little painless injection that relaxes the muscular tension that generates wrinkles. It's a relatively easy process that might have you appearing younger in just a few days. The problem with Botox is that it only treats the signs of aging, not the cause. If you've already reached your mid-30s and still have many lines on your face, Botox won't do anything to help you appear any more youthful than when you were 25. However, if you haven't hit thirty yet, Botox may be able to keep you from developing any more wrinkles as you age. Another option is laser skin treatment. Laser therapy can eliminate fine lines and wrinkles, treat acne scars, lighten dark spots, and improve the appearance of cellulite. In addition, lasers can also tighten skin by stimulating the production of collagen and elastin which reduces the appearance of jowls and loose skin due to gravity. There are several types of lasers used for different purposes. For example, photodynamic therapy uses chemicals that are taken up by cells and then activated by light. These chemicals destroy abnormal tissue without affecting normal tissue. Radiofrequency treatment uses a needle-like electrode to deliver radiofrequency energy to specific areas of the body. This energy causes tissue damage without burning actual cells, so it's perfect for treating small issues like pimples or brown spots.
