From Kitchen Accident to Collagen Obsession

After a severe burn injury, our founder Sally spent seven years working with Korean labs and nutritionists to rebuild her skin from within.


The result: clinically tested collagen that actually tastes amazing — no fillers, no metals, just results.

Sally combines two things she loves most: skincare and delicious and nostalgic beverages — so your daily glow ritual tastes as good as it works.


Sally has also since published her own research guide & cookbook, The Collagen Glow!

The book 'The Collagen Glow' by Sally Kim, with a cover showing various healthy foods and ingredients.

"The Collagen Glow presents a clear, research-grounded approach to collagen and ingestible skincare. Drawing from years of product development, clinical review, and collaboration with labs and flavor scientists, Sally breaks down collagen beyond surface-level beauty claims and explains its role in supporting skin, hair, nails, joints, and overall wellness. It highlights a key industry gap — that many collagen products fail not because of the ingredient itself, but because of poor quality, bad taste, and low daily adherence."

“Collagen is the primary structural protein of the dermis, responsible for skin strength, integrity, and elasticity. With age, endogenous collagen production declines, contributing to reduced firmness and the appearance of fine lines. Hydrolyzed collagen peptides may act as bioactive signals that stimulate fibroblast activity and support new collagen synthesis, helping improve skin hydration and elasticity."
