These days, I'm afraid of the morning sunlight. Is there an effective way to get rid of freckles?

This morning, I was looking in the mirror by the window and was startled to discover dark spots under my eyes. Before, my skin looked clear even after a quick wash, but now I'm secretly self-conscious about standing under the lights. So, whenever I have free time, I've been diligently searching the internet for ways to get rid of dark spots. Honestly, I used to avoid sunscreen, using it as an excuse to be lazy, but now I'm frustrated that this is the end of me. I asked people I know, and they all seem to be facing similar concerns. Everyone recommends different methods for removing dark spots, so it's really overwhelming where to start. Has anyone noticed a noticeable change with vitamin ampoules or functional creams? I find procedures a bit daunting, so I'd like to try at-home methods for removing dark spots. I'm really curious to know how you're dealing with the sudden increase in dark spots.
