Non-abrasive skin rejuvenation techniques such as micro needling and laser skin resurfacing can produce healthier, clearer, and younger looking skin through the process of neocollagenesis (the stimulation of collagen production) and neovascularisation (the natural formation of new blood vessels). But what are these two treatments and how do they differ?
Micro needling utilises the skin’s natural ability to heal itself as microscopic needles are used to puncture the dermis layer of the skin, triggering it to produce collagen and elastin for repair. When the body experiences damage, it sends a message to itself to start repairing, thus reproducing new collagen.
Micro needling can be done on all parts of the body including the neck, face, chest area, arms, back and hands. Not only is it used to minimise wrinkles, fine lines and pore size as well as improve acne scars and stretch marks, but it’s also effective in improving overall skin tone and texture.
On the other hand, laser skin resurfacing is a technique that’s used to direct short, concentrated pulsating beams of light at problematic areas of the skin to remove it layer by layer. In effect, the laser heats the tissue to instigate a healing process that forms new, healthy tissue. The two types of lasers that are generally used for this treatment are erbium and carbon dioxide (CO2).
Laser skin resurfacing is used to reduce skin problems such as scarring and acne. Nevertheless, it’s also effective in reducing the appearance of wrinkles and other signs of aging.
Although both treatments are used to reduce fine lines and wrinkles to make you appear more youthful, micro needling and laser skin resurfacing do have their differences:
|Micro Needling||Laser Skin Resurfacing|
|Technique||Use of tiny needles to create micro-channels in the skin and trigger a healing response||Use of heat energy to penetrate the skin’s surface & trigger a healing response|
|Pain Factor||2-3 out of 10||4-6 out of 10|
|Treatment Time||Average of 15-20 minutes per session||Average of 20-30 minutes per session|
|After Effects||A bit of redness which usually goes down after 24-48 hours. Skin may also be a bit sore & tight.||A bit of redness which usually goes down after 24-48 hours. (However, it may take longer to resolve compared with micro needling)|
|Risks||Low risk of infection and scarring as it doesn’t penetrate the skin. Also, lower risk of post-treatment hyperpigmentation as it doesn’t rely on heat||Can cause uneven skin darkening or may lead to flare-ups of rosacea or melasma|
|Suitability||Safe for all skin types as the procedure is gentle||Not suitable for all skin tones as depends on chromophores (pigment) to work|
As laser treatments aren’t suitable for every skin type and are generally considered more invasive in comparison to micro needling, be sure to do your research and consult with a skin care specialist before choosing which treatment is right for you.
