Since last year, I shared my experience of “senile plaque” on my face. Some people have been concerned about how it is after treatment, and whether there is “black back”.
nearly 10 months since the last treatment, I feel that the effect is still good. There are still some imprints, but they are still too weak than before treatment. You can compare the appearance before treatment in the original article with the current appearance in the figure below.
after treatment, I paid more attention to sunscreen than before, which should have some protective effect. Moreover, I also experienced a photon therapy after laser treatment. The photon itself has a certain effect on the pigmentation of the skin, and may also produce some superimposed effects.
