Collagen is the most abundant protein in your skin. From around age 25 our natural production drops roughly 1% each year, and the visible result is thinner skin, deeper lines and less bounce. That's why "collagen for skin" has become one of the most searched beauty questions in Australia.
What collagen actually does for skin
Ingested collagen peptides are broken down into amino acids and small di- and tripeptides. Studies show these peptides signal fibroblasts in the dermis to produce new collagen, elastin and hyaluronic acid — the three things that keep skin plump, smooth and hydrated.
How many mg of collagen per day for skin
Most clinical trials showing improvements in skin elasticity and hydration used 2.5 g to 10 g of hydrolysed collagen peptides daily for 8–12 weeks. Below 2.5 g the effect is inconsistent; above 10 g there's no additional benefit for skin.
What to look for on the label
- Hydrolysed / peptides (not gelatin) so it dissolves and absorbs
- Marine or bovine sourced — both work; marine peptides are typically smaller
- Added vitamin C, which is a cofactor your body needs to build collagen
Beauty Focus Collagen+
Nu Skin's Beauty Focus Collagen+ delivers 7 g of hydrolysed marine collagen peptides per serve, plus vitamin C, phytonutrients and lutein for skin brightness. That sits right in the clinically studied range and pairs well with your topical routine.
