What are the different types of lasers  and how they work?

You will see devices with buttons, knobs, and robotic-looking limbs that appear to have been taken out of the props closet for a sci-fi movie when you enter an aesthetic clinic or medspa. And although they are undoubtedly futuristic, they are not props: They are lasers, and in the proper hands, they may be effective instruments for treating a variety of skin issues, such as scarring, dullness, and dark spots.

How do lasers function?

In general, a laser is a concentrated beam of light that employs a single color to target a specific part of the skin (such a brown spot or an unwelcome hair follicle) while entirely sparing the surrounding skin.

Different skin targets in the red, blue, green, and other light wavelengths generated by lasers are absorbed. When the laser light strikes the target, it transforms into heat energy, causing the target to be destroyed and removed from the skin. For instance, yellow light wavelengths can be used to treat skin redness in patients because blood absorbs them.

What varieties of lasers are there?

There are many different types of lasers available, and only a skilled practitioner should decide which is best for you and your skin. Having said that, comprehending particular ideas might help you have an informed discussion with your aesthetic expert. Starting off, let's talk about the differences between ablative and nonablative fractionated lasers.

Ablative lasers

Ablative lasers are "wounding" lasers that burn the dermis under the skin's surface and remove the epidermis, the skin's thin outer covering, in order to promote the production of new collagen. The treated region looks smoother and tighter as the epidermis recovers and develops. The carbon dioxide laser is one example of an ablative therapy, which is more intensive than nonablative lasers and necessitates greater recovery time.

Nonablative lasers

On the other hand, nonablative lasers do not "ablate" or remove the skin's top layer. delivering heat pockets [straight] into the dermis while avoiding the epidermis. By doing that, the laser creates a controlled wound that will lead to some remodeling and contraction of new collagen. Naturally, one of the components of our skin is collagen. In our clinic even our CO2 laser is fractional laser which is not purely ablative and energy is delivered in fractions to skin.

What are the many applications for lasers?

Contrary to common assumption, lasers are employed for a variety of purposes.

Birthmarks and lasers

Laser treatment can significantly diminish the appearance of birthmarks. Pulsed dye lasers destroy blood vessels and target melanin. Pulsed dye lasers can be used to treat red birthmarks (like port-wine stains), brown birthmarks, and blue birthmarks.

Dark and red dots and lasers

Many undesirable brown and red spots on your skin, such as liver spots, age spots, sun spots, burst capillaries, birthmarks, and angiomas, can be removed using high-energy pulse lasers in a secure and efficient manner (red spots). You can have skin with a more even tone once the lasers have finished their work.

Scars and lasers

Scars of all kinds, including those left behind by surgery, acne, and traumas, can be treated with lasers. They pierce the epidermis to promote the formation of fresh, wholesome skin cells. Ablative fractional carbon dioxide lasers, Nd:YAG lasers, nonablative fractional lasers, and pulsed dye lasers are the most often utilized lasers for scar eradication.

Lasers and Hair Removal

A focused light beam is used during the medical treatment of laser hair removal to eliminate unwanted hair. The pigment (melanin) in the hair absorbs the light that the laser generates. Heat is created from the light radiation, which harms the hair follicles that generate hair. Future hair development is inhibited or delayed by this injury. Laser hair removal can permanently eliminate unwanted hair with a series of sessions. Even if not all hairs fall out right away, most do within a few days to a few weeks of therapy.

Resurfacing skin using lasers

Your skin is exposed to a powerful laser beam of light energy during ablative laser resurfacing. The skin's epidermis is destroyed by the laser beam (epidermis). The laser also warms the dermis, the layer of skin beneath the epidermis, which encourages the creation of collagen over time and improves skin tone and texture.

What is a low-level laser?

However, lasers aren't just employed for hair removal. Low-Level Laser Therapy (LLLT) is a relatively recent procedure that promotes hair growth by using low-power lasers. Theoretically, LLLT activates hair follicle stem cells and moves them into the anagen (growth) phase of the hair cycle.

Can lasers and other in-office treatments be used together in one session?

Quick response: Yes! You may have filler or Botox in the same procedure, depending on the laser you and your practitioner select. Since fractional lasers are safe and produce a pretty dramatic outcome, some professionals will expressly advise using injectables during the same session. we frequently mixes microneedling with non-ablative laser therapies to enhance the outcomes.
