Laser treatments have become the mainstay of skincare treatment, treating a wide range of concerns. From reducing fine lines and wrinkles to improving texture and skin tone, lasers are now essential in every dermatologist’s kit. But did you know different types of lasers are used in cosmetic treatments?
Two of the most commonly used lasers for skin are ablative and non-ablative lasers. Each laser type has its unique benefits, suitable applications, and considerations that help dermatologists determine the best option for you.
Let’s deep dive into the world of lasers to understand the key differences between ablative and non-ablative lasers and which one may be right for you!
What are Ablative Lasers?
Ablative lasers use intense wavelengths of light to remove the epidermal or outermost layer of the skin and heat the underlying skin (called the dermis). This helps stimulate new collagen fibres to grow, leading to skin tightening and texture improvement. These lasers also remove any damaged tissue on the surface, revealing fresh skin underneath.
Two commonly used ablative lasers are the Co2 and Erbium YAG lasers. In hortman Clinics we are using Erbium YAG lasers. Ablative lasers are more invasive than non-ablative ones but help achieve dramatic improvements after just one session. However, downtime of a few weeks may be required following skin treatment with ablative lasers.
Ablative lasers are effective in treating:
- Deep wrinkles
- Scars of all types, including acne scars
- Sun damage
- Age spots
Pros and Cons of Ablative Lasers
- The results are often dramatic
- Only one or a few sessions will provide a noticeable improvement in skin texture and appearance.
- The procedure requires more downtime compared to non-ablative lasers.
- Side effects like redness, swelling, and scabbing may occur post-treatment
- Healing can take several weeks
- There is a higher risk of complications, such as hyperpigmentation or infection.
What are Non-Ablative Lasers?
Non-ablative lasers are non-invasive in nature and, therefore, are also called non-wounding lasers. They deliver specific wavelengths that target the deeper skin layers without removing the outer layer. In doing so, they stimulate collagen production, promote skin regeneration, and improve skin appearance over time.
They are an excellent treatment choice for people who wish to improve their skin texture, skin tone, fine lines, mild wrinkles and pigmentation issues.
Since non-ablative lasers are gentle, they are ideal for those who do not want minor changes. For the same reason, one may require multiple sessions to get the desired effects. The downtime with these lasers is also a few days compared to several weeks with an ablative laser.
Uses of non-ablative lasers
Non-ablative lasers are used to treat:
- Fine lines
- Age spots
- Wrinkles
- Scars
There are different types of non-ablative lasers, the two most commonly used ones being:
ClearSilk laser is a gentle laser used to treat pigmentation, mild wrinkles and fine lines.
Nd: YAG laser is commonly indicated for pigmentation, mild acne scars, and improved overall skin texture. It may be used for hair removal and vascular lesions.
Pros and cons of non-ablative lasers
Side-by-side comparison
To help you understand the difference between ablative and non-ablative lasers, here’s a quick comparison:
Ablative lasers are high-intensity treatments, whereas non-ablative lasers are low to moderate.
Skin Concerns Treated: Ablative la
Ablative lasers are suitable for treating deep wrinkles, scars, significant sun damage, and age spots. Non-ablative lasers, on the other hand, are effective for treating fine lines, pigmentation, and mild scars.
Since ablative lasers are more invasive, you may require a downtime of a few days to a few weeks, depending on the type of laser used. Non-ablative lasers, being minimally invasive, require just a few days of downtime to help you recover
Ablative lasers are not suitable and recommended for people with darker skin tones as these lasers may cause hyperpigmentation. Non-ablative lasers are suitable for all skin tones.
The cost of ablative laser treatment is higher than that of non-ablative lasers due to the intensity of therapy and the equipment used.
The results of ablative laser treatment are dramatic and longer-lasting, whereas those with a non-ablative laser are usually gradual (over a period of time) and may require multiple sessions.
Who should choose Ablative Lasers?
Ablative lasers may be used in people who:
- Have significant signs of facial ageing (loss of elasticity, deeper skin wrinkles)
- Have deep or pitted facial scars
- Wish to get long-lasting or permanent results
- Can take time off work to recover after the procedure
- Wish to get a dramatic skin resurfacing
- Are over the age of 40
- Are willing to invest in the recovery/downtime
Who should choose Non-Ablative Lasers?
Non-ablative lasers are recommended for individuals who:
- Wish to address fine lines, mild acne scars and pigmentation
- Have mild to moderate signs of ageing
- Are younger than 60
- Are open to undergoing multiple sessions
- Are looking for treatments with a shorter downtime
Can non-ablative lasers treat deep wrinkles?</h2?
Non-ablative lasers are not very effective for deep wrinkles. They are better suited for mild to moderate wrinkles, fine lines and other skin concerns.
How long does recovery take for ablative lasers?
Recovery following ablative laser treatment can take several days to weeks, depending on the laser type and the extent of the treatment.
Are laser treatments safe for dark skin tones?
Ablative laser treatments are not recommended for people with darker skin tones, as they cause pigmentation. Non-ablative lasers are generally safer for people of all skin tones. Always consult with a professional to determine the best treatment for your skin type.
Combining Treatments
In several cases, dermatologists combine ablative and non-ablative laser treatment to offer patients a more comprehensive solution to their multiple skin concerns. For instance, they may begin with an ablative laser treatment to address deep wrinkles and scarring, but this may be followed by a non-ablative laser treatment for pigmentation and fine lines.
Your dermatologist will discuss with you if they plan to combine laser procedures during your consultation appointment. To know more, book an appointment today!
Conclusion
Ablative and non-ablative lasers are routinely used in cosmetic treatments. To choose between the two, your dermatologist will understand your concerns and evaluate your skin condition to determine the best solution for you. While ablative lasers offer dramatic and long-term results, non-ablative lasers are gentler and bring about gradual improvements with minimal downtime.
Always consult a certified dermatologist for your skin concerns and allow them to determine what is most suitable for you. Whether you’re looking for a quick fix or a more subtle, gradual approach, there’s a laser treatment that can help you achieve your desired skin goals.
