thanks for these questions!
There are many different types of LASER (Light amplification by stimulated emission of radiation). Mainly 3 types, the nonablative, subablative and ablative.Broadly speaking, it helps skin with wrinkles, pigmentation and scarring.
By doing ablative laser(not non-ablative), medically speaking, its using the principle of selective photothermolysis. There is removal of skin in a precisely controlled fashion with resultant minimal surrounding thermal damage. This results in well-organised skin cells with compact collagen and elastic fibers in the skin.
I would not say that the skin is more “vulnerable”, but will say its newer, younger and sensitive skin.
Nonablative laser (eg Nd-Yag laser) there is minimal downtime. Its used for superficial fine wrinkles, pigmentation and skin rejuvenation. Other non ablative laser can also be used for small fine blood vessels (telangiectasia).
Ablative laser (eg CO2 lasers) has 5-7 days downtime. Its used for acne scarring, wrinkles and pigmentation.
Side effects include hyper/hypopigmentation, scarring, persistent redness and infection.
There is so much to discuss regarding all the laser treatments and if you are suitable. Especially the pre and post laser care.
It will be best to consult and discuss with the doctor who is experienced in doing laser.
Thanks
