Horrifying
I've used sunscreen every single day for around 25 years after having treatment for facial eczema and was told during treatment to keep the sun off my face.
I still have slight pigmentation which shows up slightly during the summer even though I use SPF 40 under make up.
It's really important to start young because a friend of mine was told by a dermo that the ulcer/ growth on her nose was most likely from sun exposure 30 years ago when she worked overseas.
