The content involves industry insiders, but I think it is necessary to let the majority of beauty seekers know the truth. 1, low labor costs: acid brush program is simple to operate, mostly operated by nurses or therapists, non-doctor operation. 2, large profit margin: a brush acid cost about five or six hundred dollars, while the cost of drugs is only a dozen dollars. 3, fast results, high repurchase rate: after brushing acid skin instantly pink pink, whether it is facial pigmentation, or rosacea, or enlarged pores, in the short term will see obvious results, but the good times will not be long, and then again, because you have seen the results, you will go to the beauty agency again, asked to brush acid treatment. 4, cultivate potential customers: for some diseases, acid brushing is only a temporary relief of skin symptoms, and does not fundamentally solve the skin problem. And after long-term acid brushing, it leads to sensitive skin symptoms, often red, hot, itchy, sensitive to cold and heat, and intolerance to the original use of skin care products. This sets the stage for the further development of other treatment programs. For example: red and blue light, photon, radio frequency and so on. From then on, you will never be able to leave this beauty salon. Personally, I am very much against excessive acid brushing. Acid brushing is not out of the question, but you have to master the indications, what skin problems should be brushed acid? What kind of acid should be brushed? How often to brush? How long to brush for? Only by understanding these issues can acid brushing realize its true value and significance. This is the clinical level of the doctor, put forward higher requirements, not only to understand the acid, but also to understand the skin, which is not a nurse or therapist can do.
