I have blemishes on my face ㅠㅠ Please recommend some effective products for managing freckles.

I was terrified when I looked in the mirror and saw dark spots under my eyes ㅠㅠ I've been diligently applying sunscreen, so why do these appear? Sob sob... I want to manage them before they get darker, so please recommend some effective products for treating melasma! Are there any melasma treatments you've seen results from that you can buy at Olive Young or online? Haha

My budget doesn't allow me to go to a dermatologist, so I want to try handling it with home care. I would be really grateful if you could recommend a gentle, non-irritating brightening ampoule or cream for managing melasma! Everyone who comments will become a skin beauty lol. Thank you in advance ^^
