Not a derm, but a skincare enthousiast. From what I know, skin is an organ, and as many organs it sustains damage as we live and use them (with the exception of the liver that can regenerate providing you don’t go too hard on it). UV rays attack the skin and our skin works hard to protect us. It thus gets old from all that work.
Cancer is when cells lose the plot and become mad. So instead of working FOR you, they start to multiply like crazy and eat everything in sight like hungry caterpillars. Including healthy functioning cells.
Anyone can develop a cancer but it’s more likely if you’ve given your cells a reason to overwork and burnout. Like UV rays, smoking, bad food, lack of sleep, stress, drinking to excess etc…and of course old age.
Not sure I explained wekl, but this is my understanding!
