Intense Pulsed Light

Intense pulsed light (IPL) is a technology used by cosmetic and medical practitioners to perform various skin treatments for aesthetic and therapeutic purposes, including hair removal, photorejuvenation (e.g. the treatment of skin pigmentation, sun damage, and thread veins) as well as to alleviate acne and other dermatological disorders.

 

What are the applications of IPL?

Blemishes

Blemishes are marks or areas of discoloration on the skin. They can be raised off of the skin or flat, and come in a range of colors. Since there are many different types of blemishes with many different causes, the treatment for each is a little different. Common types include acne, scars, birthmarks, age spots, and an uneven skin tone.

Acne

One of the most common blemish-causing conditions is acne. This can cause both raised pustules and pimples as well as flat blackheads and whiteheads. These happen when a hair follicle gets clogged with a naturally-produced oily substance called sebum, dirt, or bacteria, and can also be caused by ingrown hairs. Most people have acne during puberty, when hormonal changes cause the body to produce too much sebum, which increases the changes of clogs. Over-the-counter (OTC) cleansers and medications can reduce sebum, soothe inflammation, and clean out pores for people with mild or moderate acne, but those with severe acne may need prescription anti-inflammatory and medications to regulate hormonal changes.

Scars

Scarring is another of the most common blemishes. It’s caused by too much collagen building up after an injury, and can range widely in size, color, and texture. Though most scars fade over time, using skin oils containing vitamin C, chemical peels, dermabrasion, and laser therapy can reduce the appearance of large or brightly-colored scars. One exception to this is keloid scarring, which continues to grow even after skin has healed, and doesn’t respond well to many types of treatment.

Birthmarks

Blemishes that appear as flat patches of discoloration that are present at birth or develop when a person is very young are called birthmarks. They can range widely in size, and are typically black or brown, as in the case of moles; or red, as in the case of port wine stains and stork bites. They’re almost always benign, and are caused by too much pigmentation in one particular area, or blood vessels coming close to the surface of the skin.

Age Spots

Sun exposure may cause age spots or liver spots in older people or younger people who tan a lot. Like birthmarks, they’re generally flat, and can be found anywhere on the body, though they’re most common on the face and hands. They usually look like small gray, black, or brown marks.

Uneven Skin Tone

A blotchy skin tone is also a very common, though often more subtle, form of blemish. Also known as hyperpigmentation, it’s caused by an irregular overproduction of melanin. Since melanin production is influenced by sun exposure, hormones, and skin injury, too much of any of these things can change skin tone for the worse.

Preventing Blemishes

Though it’s impossible to prevent birthmarks, the chances of getting other types of blemishes can be greatly reduced through proper skin care. Wearing sunscreen and avoiding tanning can help prevent age spots and can help with an uneven skin tone, and staying hydrated can help keep skin looking healthy.
