Your much better off using a retinoid than dans regimen for scarring (keeping the small budget here), but make sure you have cleared up your acne first before looking to treat scars

I'm sorry if I sound like an idiot but I've just started trying to fix my scars so I don't know much. What exactly is a retinoid? Is it an ingredient or product?

tis a product like 'retin-A' or 'Differin'

Has either/or proved to be better? Are they both over the counter? Once again, sorry for the lack of knowledge.

you need a prescription for retin-a but you can by a retinol over the counter which is a lot less stronger version of retin-a I use the RoC brand

I've used differin before for a long period of time. It didnt work for me. I am on regimen (Dan's products) and I am finding that my scars are starting to disappear and I've only been using it for a week! I think it's because the bp peels some of the skin off, whereas differin just made my skin more red.

Of course everyone has different experiences so I think its entirely up to you what you prefer.
