I started feeling like I had a tired and older look when I hit 35. I have freckles and they get worse with sun exposure. I went to a local "spa" and paid $140 for a mini dermabrasion and chem peel and honestly didn't notice much of a difference... my intentions where not to go back.
My neighbor happened to have a cousin who is a nurse by trade and also when to derm school. She offered a full microderm and peel with an after care kit for under $100. HUGE difference. I have reversed tons of sun damage and my skin is tighter and clearer.
If I have bouts with some slight acne this clears it up as well. I think it's a great regiment to get into. I go every 4 months or so, but if I had the cash I'd go every other. Try this before getting anything else "done" if you just need a light lift to the tone of your skin.
