Under the Hood

Targets collagen support, skin barrier quality, and deficiency-related nail or hair issues.

May improve skin elasticity and hydration
May improve brittle nails
Supports collagen synthesis
May help acne only when zinc status is low or inflammation is relevant

Expected Results

Skin and nail outcomes usually need 8-12 weeks; hair outcomes take longer and depend heavily on deficiency status.

Smoother skin texture in some users
Less nail brittleness
Better protein/collagen intake coverage
Little effect on genetic hair loss without a deficiency

Biological Synergies

Collagen peptides + Vitamin C

Vitamin C is required for collagen hydroxylation, while collagen peptides provide amino-acid building blocks.

More rational support for skin elasticity and connective tissue than collagen alone in low-vitamin-C diets.

Omega-3 + Zinc

Omega-3s may support inflammatory balance, while zinc supports skin barrier and wound-healing biology when intake is low.

Useful for users with inflammatory skin patterns and low dietary intake.
