As for the question asked by the landlord:
First: Picosecond will not accelerate skin aging, but it can brighten skin tone and rejuvenate skin. You mean the skin is a little old after a few years, which may just be a sign of normal skin aging. With the growth of age, people's skin is drooping and aging at a slow speed every day. Isn't it normal for the skin to show some signs of aging compared with a few years ago?
Second: as for what spot it is, it can only be determined after the doctor's face-to-face consultation. Even if you take photos and send them to a doctor for consultation, the doctor can't be 100% sure what spots you have, because different angles and different lighting will have different effects. And most people's faces are mixed with several spots. How to treat it must be decided after face-to-face consultation by doctors. The specific number of picosecond laser sessions is related to the personal situation of the beauty seeker. If the beauty seeker's condition is serious, in addition, the skin will become very dry one week after operation, and some people will think that the skin will become dark yellow. This is a normal phenomenon because the skin is metabolizing old cells to grow new ones. Apply mask frequently within a week, moisturize and prevent sun!
As for the third question, it is actually very simple. Choose a large, well-qualified professional medical institution, and don't be greedy and cheap to choose a photo studio or beauty salon. The market price of picoseconds is already relatively transparent. If it is much lower than the market price, it must be carefully considered.
