How do you manage blemishes and freckles?

My face is full of blemishes.

Lately, every time I look in the mirror, I am so self-conscious about the blemishes on my face. There are light spots like melasma and freckles, and it feels like the fine pigmentation is gradually increasing as well.

Please recommend any methods you have found effective, ranging from at-home care to dermatological procedures.

I am also curious about things like Vitamin C serum, laser toning, and regenerating cream, and I would like to hear reviews from those who have actually tried them. My skin tends to be sensitive, so I would prefer a method that is gentle. Please let me know if there are any skincare routines that offer great value for money.
