Microdermabrasion is one of the great skin treatment success stories of the last few decades. A fast, simple and effective procedure, the technique is used to smooth out wrinkles and fine lines, reduce discolouration and sun spots - and generally improve overall skin appearance.

How does it work?

Microdermabrasion's genius is its simplicity. It doesn't require the use of lasers, harsh chemicals or any invasive technology. Instead, a pressurised jet of tiny zinc or aluminium oxide crystals are directed across the surface of the skin.

As the crystals hit the skin they dislodge and remove any damaged or dead cells. All of this material is then vacuumed away into a sterilised, closed unit. The entire procedure can last as little as half an hour.

How does it feel?

Microdermabrasion is a quick and painless procedure. Patients often report a light tingling sensation on the surface of the skin during treatment, but no pain or major discomfort. Although those with particularly sensitive skin may feel a slight prickling, it's generally regarded as one of the most comfortable skin treatments available. It also requires no anaesthetic.

Are there any side effects?

Because microdermabrasion doesn't involve any aggressive chemicals or invasive surgery, side effects are minimal. Most people experience a slight redness in the treated area for up to a few hours after the process, but rarely anything other than this.

After the treatment, you should try to avoid direct sunlight for a few days – and apply sunscreen when outside at all.

What about the results?

Microdermabrasion produces some of the most impressive results of any non-invasive treatment. For common complaints such as light wrinkles, sun spots, pigmentation issues and acne scarring it can have a significant positive effect.

Many people use the treatment as a way to simply increase the "freshness" of their skin – with the result of a more glowing complexion and smoother skin texture. Indeed, some doctors (including New York Magazine's Doctor of the Year, Dr. Mehmet Oz) recommend monthly microdermabrasion to regularly clear pores.

For more deeper skin conditions (such as severe acne scarring) a series of microdermabrasion treatments may be needed before results start to be seen. However, for serious scarring it may be necessary to use more intensive techniques.

Where should I go for treatment?

Though microdermabrasion is a safe procedure, you should always make sure you visit an experienced treatment centre, preferably one with medical registration.

Good clinics will offer an initial consultation, as well as preparation for treatment using cleansers and lotions. They will also customise the vacuum pressure according to your skin type and apply moisturiser and sun block after treatment.
