Is there a way to treat freckles and blemishes at home?

Perhaps because I was exposed to so much sun all summer, I've started noticing melasma and blemishes appearing one by one on my face. It bothers me, but I'm hesitant to get dermatological procedures right away, so I wanted to look into home care methods that I can manage consistently at home. Lately, I've been using the BOH Vitaknergy Dark Spot Toning Cream; I heard it contains vitamins that brighten skin tone and are good for blemish care. So, I've been applying it to the areas I'm concerned about morning and evening, and I definitely feel like my skin is getting a bit brighter. However, since melasma doesn't go away easily once it appears, I feel like there are limits to managing it on my own. That's why I'm curious what home care methods you all use to manage melasma and blemishes. If you have any effective methods or routines other than vitamin products, sharing them would be really helpful. I really want to see my skin tone brighten a little bit through consistent care, so please let me know if you have any good tips!
