Because everyone has different reasons for acne, not everyone's problems can be simply said: don't eat anything that gets angry, or pay attention to rest.
I don't know how many beauty salons I ran and how many skin care products I changed before. Finally, it is better to see a doctor. And the medicine is cheap (I specifically asked the doctor not to prescribe strong drugs containing steroids or hormones. What I want is "treatment", not "immediate effect" and then "recurrence" =. =)
So, as for acne, I still insist on seeing a doctor. I believe in professionalism, not a "beautician" who has been trained for a period of time.
======================
Then, if you want the beautician to solve the problem of red acne marks, I have no problem. Because this piece is the maintenance part.
Personally, I think all skin care is based on moisturizing and oiliness. This is especially true for mixed skin. My way to deal with acne marks is to whiten on the basis of moisturizing. After all, the red mark is a problem of pigmentation (and sun protection is very important, otherwise it is useless to do more maintenance).
Now I dare not say that there are no acne marks at all, because acne will occasionally grow during the physiological period. But even Su Yan is not worried about the obvious acne marks.
However, if it is a scar left by picking out acne (that is, a scar with a little depression), it is not a problem that can be solved by maintenance. This is a problem that can be managed by "micro-shaping" such as laser.
