Please share a whitening skincare routine to brighten up my dull complexion.

Now that spring is here, I want to wear bright, cheerful clothes, but my complexion looks dull, so I don't look good in them. I want to brighten my overall skin tone, so what kind of whitening routine does everyone have? Right now, all I do is apply a Vitamin C ampoule, but I don't think that's enough.

I’ve heard that exfoliation and hydration need to be combined for good whitening results, so I’m curious about the specific order or product combination. I’m being cautious because I heard that an improperly planned whitening routine can actually cause breakouts. Applying sunscreen thoroughly during the day is a given, but I need some special care for the evening.

To those of you with bright, fluorescent-light skin, could you please share just a little bit of your personal brightening routine? I’m getting dizzy just wanting to have such flawless skin haha. I’ll be waiting for your tips!
