If you have not already started to look after your skin, the "20s" is the time to start. Prevention is key here. I can comfortably say this as I am 49-years-old and wish I had of taken on a little bit more skin advice. Luckily I have been in this industry for a very long time, but the one thing I wish I had been more serious about is Sun Protection.
I can not stress enough the damaging effect the sun can have on your skin. The consequences are premature ageing which includes lines, wrinkles, pigmentation, skin cancer, open pores and uneven skin tone and texture.
These are all very hard to reverse and could have been so easily prevented with one simple product, SUNSCREEN!
