I was a patient for about 5 years during which time I had TCA treatments for my acne scarring. Dr Dekkinga's staff did the treatments as well as he did. He promised me that I would have smooth skin, however, after a few months of treatments, me skin still had many acne scars as well as hypopigmentation marks on both sides of my face. At one time, they did not cool the treatment, and I ended up scarring very badly from that particular treatment. When I made an appointment regarding that treatment, Dr Dekkinga would not take blame for that TCA mishap. I am now seeing another dermatologist who said that TCA is very outdated, and they have not done them for over 10 years. I am very disappointed in my overall experience with Dr Dekkinga and his staff.
