Does derma roller work for a firmer skin than collagen supplements?

[domitiwhynotme]

I don't have enough money for a collagen supplement so I take vitamin c and I'm planning to buy derma roller. Does it work?

a derma roller is like 1.29$ you have almost nothing to lose by getting it

Just buy one off ali express for 10 cents and try it out

Yeah. So I considered it rather than a collagen supplement. A collagen supplement online is like 20 dollars
