Collagen for skin: the real science behind the buzz

Collagen supplements are a billion-rupee category in India. But do they work? The honest answer: yes, with caveats. Here's what 30+ peer-reviewed studies actually show.

What collagen does in your body

Collagen is the most abundant protein in your body — it makes up the structural framework of your skin, bones, joints, hair, and nails. Production peaks in your 20s and then drops by about 1% per year. By 50, you have lost ~25% of your skin's collagen.

The myth: "Eating collagen builds collagen"

Technically, your stomach breaks all dietary protein down to amino acids and small peptides. So the collagen molecule itself does not survive digestion intact. So why do studies still show skin improvements?

The reality: collagen peptides act as signals

Hydrolysed collagen peptides — the kind in modern supplements — are short chains of 2-5 amino acids. These specific peptides (hydroxyproline-proline, hydroxyproline-glycine) appear to signal your fibroblast cells to ramp up their own collagen production. A 2019 meta-analysis of 11 clinical trials confirmed measurable improvements in skin elasticity and hydration after 8–12 weeks of daily use.

The catch: you need the cofactors

Your body needs Vitamin C and glutathione to actually synthesise new collagen from amino acids. Most collagen supplements skip these. The result: you give your body the signal but not the building blocks.

This is why we built our Collagen + L-Glutathione effervescent with the full stack: 5,000 mg hydrolysed collagen peptides + 100 mg L-Glutathione + 50 mg Vitamin C + Hyaluronic Acid.

Realistic timeline

• 2–4 weeks: Improved skin hydration (most reliable, most-studied effect).
• 8–12 weeks: Visible improvement in skin elasticity and fine lines.
• 3–6 months: Stronger nails, joint comfort, hair quality changes.

Consistency matters more than dosage. 5,000 mg every day beats 10,000 mg three times a week.
