Im looking for a collagen supplement but Dermacare is too expensive

Absolute Collagen, Revive Collagen, Ingenious Collagen and Gold Collagen are all more affordable and use decent types/ sources of collagen and have reasonable data to support their efficacy, so have a look at those.

You need 8,000=10,000mg of hydrolysed collagen per day to make a difference so take that into consideration when looking for a collagen supplement.
