Laser treatments have been a staple in aesthetic procedures for decades, especially when it comes to addressing pigmentation concerns. With continuous advancements in technology and the introduction of new innovations, the market is now flooded with a variety of laser treatments.
For those unfamiliar with these treatments, lasers are generally divided into two categories: ablative and non-ablative. Ablative lasers work by removing the outermost layer of skin and heating the deeper layers to stimulate collagen production. This is commonly referred to as laser skin resurfacing and is used for issues like deep scars and enlarged pores.
On the other hand, non-ablative lasers target pigmentation irregularities and skin texture without removing skin layers, making them less invasive.
With so many options and various laser brands heavily promoted, it can be difficult for consumers to understand the differences and determine which one is right for them.
In this article, we will share important insights about non-ablative laser treatments to help guide your decision.
1. There’s No Universal “Best” Laser
There is no one-size-fits-all solution when it comes to lasers for pigmentation. The right laser for your specific condition depends on the type of pigmentation you have. Many people inquire about the Pico laser due to its recent popularity and extensive marketing, but this does not mean it is the best option for everyone. Different lasers target different layers of the skin and types of pigmentation.
Consulting an experienced doctor is essential to assess your skin and recommend the most suitable laser treatment for your condition.
2. Lasers Are Designed for Specific Pigmentation Types
There are various types of lasers designed to address different pigmentation issues. Shorter wavelength lasers like yellow and ruby lasers are effective for treating superficial pigmentation such as freckles, sunspots, age spots, and certain forms of epidermal melasma.
For deeper pigmentation conditions such as dermal melasma, acne scars, and certain birthmarks, longer wavelength lasers like the Pico and Q-switched lasers are recommended.
At ERH Skincare Malaysia, we offer a range of non-ablative lasers:
- Yellow Laser (577nm)
- Ruby Laser (695nm)
- Q-switched Laser (1064nm)
- Pico Laser (dual wavelength: 532nm and 1064nm)
Each of these lasers operates at different wavelengths, with the Pico laser being unique in offering both short and long wavelengths. However, the shorter wavelength of the Pico laser may not be suitable for all skin types, especially for those with Asian skin due to the higher risk of side effects.
Even lasers with the same wavelength can differ in their functions based on pulse duration, which refers to how long the laser energy stays on the skin before the next pulse. Your doctor will select the most appropriate laser based on the specifics of your pigmentation and skin type.
3. Some Lasers Offer Additional Benefits
While lasers are primarily known for treating pigmentation, they can offer additional benefits such as improving skin texture, reducing acne bacteria, exfoliating the skin, soothing redness, and rejuvenating the skin. Discuss your goals with your doctor to choose the laser that best aligns with your needs.
4. Non-Ablative Lasers Do Not Thin the Skin
Non-ablative lasers, like the ones offered at ERH Skincare Malaysia, do not thin the skin. These lasers target pigments below the skin's surface, similar to the process of tattoo removal, without compromising the skin’s integrity.
5. Certain Lasers Are Suitable for Sensitive Skin
While some lasers may not be suitable for sensitive skin, the yellow laser is gentle and can help reduce inflammation and redness, making it ideal for individuals with more sensitive skin. On the other hand, lasers like the Q-switched laser and Pico laser may cause dryness or irritation in sensitive skin.
6. Comfort and Downtime Vary
Most non-ablative laser treatments are not painful, and a thin layer of numbing cream is often applied before treatment. However, lasers like the yellow laser or Q-switched laser are typically well tolerated without numbing.
The downtime after treatment varies depending on the type of laser and the skin condition being addressed. Shorter wavelength lasers may cause temporary scabbing or redness for up to a week, while longer wavelength lasers affect deeper layers with less visible downtime. Your doctor will adjust the laser settings according to your skin's needs.
7. Complete Pigmentation Removal May Not Always Be Achievable
Achieving complete pigmentation removal may not always be possible. Superficial issues like freckles can often be treated in just one to three sessions, while conditions like melasma may require multiple treatments. The overall health of your skin also plays a role in the effectiveness of treatments.
8. Minimizing Potential Side Effects
The most common side effect of laser treatments is hyperpigmentation, where treated areas temporarily or permanently darken. Choosing the right laser and adjusting energy settings can help minimize this risk. Other mild side effects such as redness or dryness are usually temporary.
9. Post-Treatment Care Is Crucial
Proper aftercare is essential for optimal results. Following treatment, avoid direct sun exposure for one to four weeks, depending on the type of laser used. It’s also important to apply sunscreen regularly and use recovery creams as advised, especially after more intensive treatments.
10. Lasers Are Generally Safe During Pregnancy
Most lasers are considered safe during pregnancy, particularly in the first and second trimesters, as the treatment is localized to the skin and does not affect the body or fetus. However, always consult with your gynaecologist before undergoing any laser treatments during pregnancy. Bright lasers like the ruby and yellow lasers should be avoided in the later stages of pregnancy.
For treating acne during pregnancy, hormonal changes may affect treatment outcomes, so it’s important to monitor your skin's condition and consult with your doctor for guidance.
When administered by skilled professionals, lasers are safe and effective for addressing pigmentation and enhancing skin quality. At ERH Skincare Malaysia, our doctors conduct thorough skin assessments using advanced tools like the Visia skin analysis system to tailor treatments that best suit your skin type and concerns.
