I have used three SANA series. One is thin in the lower body, the other is thin in the whole body, and the other is your thin face.
I am 20 years old this year. I don't think it's effective to use that thin face. I don't know about your skin. Mine is sensitive and dry skin. After I used it, I just put it on, and I felt very cold, and then I felt slightly hot. I think it should work. Then I used it for about three days, and the problem appeared. My face became allergic and red, and I stopped using it. Most people say that people with different skin have different effects, so if you have sensitive skin, don't use it.
Furthermore, I actually know a lot about face-lifting methods. If it is a baby, it is best to be thin. If you want to face-lift, choose moisturizing. In fact, it is impossible to achieve good results only by this external application.
Tell you a good idea, but stick to it. Don't expect any face-lifting products to turn your cake face into a melon face in a short time. Buy a scraping tablet and use it with the face-lifting cream you bought. There is such a scraping method on the internet. It's no use just putting it on your face. Cooperate with massage.
Finally, face-lifting and slimming itself is a long-term process. I hope the landlord will not pursue speed and use some slimming products, not to mention that you are only 17 years old. If you don't want your face to be red and swollen in the future, don't use these products, it will really hurt your skin.
Scraping massage is the best method. As long as you insist, I guarantee that you have a healthy thin face.
Ps: Sana series products. . . I can only say. . Useful. . But not as good as I thought. . . It is by no means as effective as advertised on the Internet. . And the skin will remain red for a long time after that slight spicy feeling. . I'm afraid my skin can't stand it. . .
