Everything you need to know about laser treatments
Laser treatments can be used to treat a number of skin-related issues, including skin damage and pigmentation.

Laser treatments have become increasingly popular over recent years as it is a minimally invasive, effective way of targeting specific skin concerns.

Dr Anjali Mahto, leading consultant dermatologist and founder of Self London, has answered the most commonly asked questions regarding the treatment.

What is it?

Laser treatments use a “highly focused and intense beam of light” which targets specific skin issues.

“It delivers precise energy to target specific skin concerns, such as sun damage, wrinkles, and pigmentation irregularities,” Dr Mahto explains.

“By stimulating collagen production and promoting skin regeneration, lasers can rejuvenate and improve the overall texture and appearance of the skin. They are a popular non-invasive or minimally invasive option, offering effective results with minimal downtime.”

How does it work?

The laser emits a concentrated and coherent beam of light at a specific wavelength.

“When the laser light interacts with the skin, it targets and heats up specific skin structures, such as pigment, blood vessels or water, depending on the treatment goal,” the expert says.

“This controlled energy absorption triggers a response in the skin, stimulating collagen production and promoting skin rejuvenation.”

Is it painful?

Laser treatments can result in discomfort; however, it can depend on a number of factors.

“More patients report only mild sensations during the procedure. The level of discomfort depends on the type of laser used, the patient’s pain tolerance, as well as the treatment area,” Dr Mahto states. “Non-ablative and fractional lasers typically cause minimal discomfort, akin to a sunburn sensation.”

The consultant dermatologist adds, “Post-treatment, patients might experience mild redness or sensitivity, which usually subsides within 2-7 days, depending on the type of treatment. ”

Is it safe for skin of colour?

According to the expert, people of colour may be at higher risk of complications, such as adverse reactions, from laser treatments.

“Laser treatments for skin of colour require special considerations due to a higher risk of complications like hyperpigmentation and hypopigmentation,” Dr Mahto explains.

“The melanin in darker skin can absorb more laser energy, increasing the risk of adverse reactions, and so pre-treatment assessment is crucial to select appropriate lasers and settings. Cooling measures and test spots may also be performed to minimise risks.”
