i just wanna clear and plump my face bc my skin is too thin
If you feel that your skin is too thin, it might be a sign of overexfoliating, so I'd reduce the Overnight exfoliating treatment to once per week.
The single most important step for protecting against dark marks and helping heal the existing ones is a daily broadspectrum sunscreen in the AM.
For plumping your skin up, I'd suggest a moisturizer in the PM (you can also use it in the AM before your sunscreen in case the sunscreen doesn't feel hydrating enough). An example vegan product: https://whatsinmyjar.com/product/e-l-f-e-f-happy-hydration-face-cream. I don't think you really need the hyaluronic acid serum (moisturizers already contains the same ingredients), but it's not harmful if you like using it.
In terms of treatment for blemishes and pigmentation, I'd consider adding an azelaic acid product in the AM and, if your skin isn't particularly sensitive, a retinoid at night.
Example azelaic acid product: https://whatsinmyjar.com/product/the-ordinary-azelaic-acid-suspension-10.
For a retinoid, something like this can work: https://whatsinmyjar.com/product/drunk-elephant-a-passioni-retinol-cream. I'd suggest starting it 2 a week and slowly increasing the frequency to every other night, and then every night if your skin tolerates it well.
And please don't forget a daily broad spectrum sunscreen!
