How often to apply hyaluronic acid after dermapen if that's all I have? (Photo)

Used a dermapen on my own accord today with hyaluronic acid on my stomach, to be precise, for stretch marks and lax skin (minimal), more so wanting to target stretch marks, used 12 pin needle cartridge and 2mm length. All I have is hyaluronic acid for a moisturizer unfortunately. I'm also taking vitamin c and collagen internally but working with what i've got, can I keep applying the hyaluronic acid daily? What would you suggest?
