Had microdermabrasion. Spent too long and hard going over the same area, causing redness to the skin which was present for some days. Worried that this could cause red veins on the face. Face is too delicate for overdoing. Also, did not use an antiseptic to finish, before the moisturiser. The crystals were still on my face when I got home so I had to wash it again and then moisturise. They only used sponges to remove crystals, and this clearly was not sufficient.
