Not reliable. I saw an article recommending Roland Studio on my favorite official WeChat account and bought their service on impulse. They provided a 45-day plan, saying that according to their practice, the skin would get better in 45 days, 1000, and provided a set of skin care products, plus 10 mask, once a day for the first 7 days and twice a day for the next 35 days. Masks are not enough. I made my own plans and bought them. And the seven-day experience requires you to take regular skin care+regular exercise in your life+light diet. Seriously, if I can do it, my skin will be just as good without their products!
