My skin care routine these days: A month of home care to erase acne scars

The acne I got during puberty has cleared up, but the red marks and pigmentation left all over my face stress me out every time I look in the mirror. Concealer can only cover so much, and when I go bare-faced, my face looks so blotchy, it's a real concern. I've been consistently applying regenerative creams, but I'm frustrated because they don't seem to be enough to erase the scars I've already created.

Currently, I apply an essence containing vitamin derivatives morning and night, and a small amount of scar ointment in the evening. After about a month, the scars seem to be fading slightly, but it's not as dramatic as I expected, so I'm a little impatient. They say thorough UV protection is essential, so I apply sunscreen even indoors. Is there a more effective method?

Has anyone tried improving this type of pigmentation with home care alone, rather than laser treatment? I'd appreciate any tips on which products contain the right ingredients for the best results. Success stories from those who have overcome scars would be a great source of hope for me. I desperately want to regain my clear skin, so I look forward to hearing your insightful advice.
