I was looking at old photos of Cloud and sighed when I saw her skin now..

I was sorting through old photos on my phone out of boredom when I saw myself exactly five years ago. Back then, I didn't even bother applying sunscreen as much as I do now, but my skin had a natural glow. Now, I'm obsessed with ampoules, highly nutritious creams, and even sheet masks, but I can't seem to get that clear, clear feeling back then, which is quite sad. They say maintenance is the answer, but I guess time can't be helped. Still, if I wake up now and take good care of myself, I'll be grateful to my current self in five years. What skin habits would you tell your past self, "I absolutely must do this," or "I absolutely must not do this," and what would they be?
