What are cosmetic lasers, and what are they used for? Laser technology has come a long way in the past few years, and one application of lasers that has seen dramatic growth is the cosmetic industry. Cosmetic lasers are used for various treatments, including hair removal, skin resurfacing, and wrinkle reduction. In this article, we will discuss what cosmetic lasers are and their function. Let’s get to the details.
What are Cosmetic Lasers?
A cosmetic laser is a medical device that uses laser energy to treat various conditions and skin concerns. There are different types of laser units you can use for cosmetic purposes. Each laser type uses a different light wavelength to target specific skin concerns.
For example, an ablative laser, such as a CO2 laser, targets the top layers of the skin. This laser is typically used for more invasive procedures such as wrinkle reduction or skin resurfacing. On the other hand, a non-ablative laser, such as an Nd: YAG laser, targets the deeper layers of the skin without damaging the top layer. This type of laser is often used for skin tightening or hair removal treatments.
Common Types of Cosmetic Lasers
There are many different types of cosmetic lasers available on the market. Here are some of the most common:
- Ablative Lasers: CO2 laser, Erbium laser: These lasers are used for skin resurfacing and wrinkle reduction. They work by removing the top layers of the skin, stimulating the growth of new collagen and skin cells.
- Non-ablative Lasers: Nd: YAG laser, diode laser, Alexandrite laser: These lasers are used for skin tightening, hair removal, and treating small blood vessels. They work by heating the deep layers of the skin without damaging the top layer.
- Selective Photothermolysis: This laser technology is used for various cosmetic treatments, including hair removal, tattoo removal, and wrinkle reduction. It works by selectively targeting specific areas of the skin with different wavelengths of light.
How do Cosmetic Lasers Work?
Cosmetic lasers work by targeting specific areas of the skin with different wavelengths of light. The light energy is absorbed by the targeted area, causing the tissue to heat up. This process can stimulate the growth of new collagen and skin cells and break down unwanted hair or pigmented tissue.
Most cosmetic laser treatments are relatively short, taking only 30 minutes to an hour to complete. However, some treatments, such as skin resurfacing, may require multiple sessions to achieve the desired results.
Ensure you consult a board-certified dermatologist or plastic surgeon to see if you are a good candidate for cosmetic laser treatments. For instance, those with active acne may not be suitable for certain laser treatments.
What Are The Benefits of Cosmetic Lasers?
Cosmetic lasers offer many benefits, including:
- Minimally-invasive: Unlike cosmetic surgery, which involves cutting and stitching the skin, cosmetic lasers are minimally-invasive. This means there is less risk of infection and scarring than surgery.
- Short recovery time: Most cosmetic laser treatments have a short recovery time, with some patients able to return to their normal activities the same day. You can have the treatment and see the results in a few weeks.
- Precision: Cosmetic lasers can be precisely targeted to specific areas of the skin. This means that the surrounding tissue is not damaged, and there is less risk of side effects.
- Safe: When performed by a board-certified dermatologist or plastic surgeon, cosmetic laser treatments are safe. Serious side effects are rare, but you may experience temporary redness, swelling, and bruising after the treatment.
- Effective: Cosmetic lasers can produce dramatic results, including smoother, younger-looking skin and reduced wrinkles.
- Quick: Most cosmetic laser treatments take 30 minutes to an hour to complete.
What Are The Side Effects of Cosmetic Lasers?
Cosmetic laser treatments are generally safe when performed by a board-certified dermatologist or plastic surgeon. However, as with any medical procedure, there is a risk of side effects.
Common side effects of cosmetic lasers include skin redness, swelling, and bruising. These side effects are usually temporary and resolve within a few days to weeks.
Rare but serious side effects of cosmetic lasers include burns, scarring, and changes in skin color. If you experience any of these side effects, seek medical attention immediately. Your doctor should be able to treat the side effects and help you recover.
Tips to Prepare for Cosmetic Laser Treatment
If you are considering cosmetic laser treatment, there are a few things you can do to prepare:
- Find a board-certified dermatologist or plastic surgeon: Ensure that your doctor is board-certified and has experience performing the specific laser treatment you are interested in.
- Ask about the risks and side effects: Be sure to ask your doctor about the risks and side effects of the treatment.
- Stop using certain products: Your doctor may recommend that you stop using certain products, such as retinoids or bleaching creams, before the treatment.
- Avoid sun exposure: It is important to avoid sun exposure before and after laser treatment. Be sure to wear sunscreen and avoid sun exposure for at least two weeks before and after the treatment.
Cosmetic lasers are a safe and effective way to improve the appearance of your skin. When performed by a board-certified dermatologist or plastic surgeon, cosmetic laser treatments can minimize wrinkles, improve skin tone, and give you smooth, younger-looking skin. Ensure to ask your doctor about the risks and side effects of the treatment and follow their post-treatment instructions to avoid any complications.
