Skin may be the largest organ, but it is often the most neglected.

The most common issues women have are acne scars, age spots, wrinkles and loose skin. There are dozens of procedures to alleviate these trouble areas but the most popular are laser treatments, laser rejuvenation, laser resurfacing, microdermabrasion, Botox, dermal fillers and chemical peels.

Here is a breakdown of the more common treatments:

Thermage helps tighten skin around the face and neck without exfoliating. The procedure uses a radio-frequency device over the face to heat the deeper tissue. This stimulates collagen development. The results are often immediate with no downtime.

Microdermabrasion helps remove slight acne scarring and age spots. It’s a preferred wrinkle treatment, too, because it isn’t time consuming and has no downtime. Small crystals are sprayed across the skin to exfoliate while a suction removes dead skin cells along with those crystals.

Chemical peels, or derma-peels and chemexfoliation, are almost strictly cosmetic treatments to rejuvenate the skin and act as an anti-aging solution. The peels can correct skin irregularities by using three types of acid: phenol, alpha hydroxy acid (AHA) and trichloroacetic acid (TCA).

Peels can correct skin inconsistencies like discoloring, spots, sun damage and fine lines.

Laser resurfacing is just as it sounds. A laser is used to remove the top layers of damaged skin to promote collagen and new skin cells. It is commonly used to address fine lines and wrinkles on the face and neck.

Laser skin rejuvenation is a more advanced treatment to address wrinkles using infrared light. This alternative to surgery uses heat to stimulate collagen under the skin’s surface, making skin appear tighter.
