hi, we're glowcast

About Glowcast

Glowcast is built by an independent developer. The website is a free reference for looking up what a food does to your skin. The app is the personal layer: it follows what you eat and how your skin looks, so you can see what seems to matter for you.

Why Glowcast exists

Your skincare routine doesn't stop at skincare. If you already wear SPF, use a retinol, sleep well and drink enough water, food is the one part of the routine most people are still guessing at. Glowcast treats nutrition as skincare: not calorie counting, and not a list of foods to fear.

Eat for your glow. Glowcast turns every meal into a personalised Glow Score, so you can eat for clearer, calmer, more radiant skin.

The research on food and skin describes averages across groups of people. It is a good place to start and a poor place to stop, because people differ. That is the gap the app is built for:

Research tells you what might matter. Glowcast helps you discover what seems to matter for you.

What we are not

There is no dermatologist or dietitian on staff yet. Nothing on this site is medical advice, and nothing here replaces a clinician who can examine your skin. If you have a skin condition or take prescription treatment, talk to your doctor before changing your diet.

When a credentialed reviewer joins, their name will appear on the pages they have reviewed. Until then, the byline on every article is Glowcast, and no page names an author or reviewer who does not exist.

How content is made

Sources. Health claims rest on tier 1 sources wherever they exist: peer-reviewed research, systematic reviews, clinical guidelines and government data. Tier 2 is major publications and tier 3 is reputable industry sources. Each article lists its sources and cites them where the claim is made.

Evidence grades. Food, goal and comparison pages grade each claim on two separate axes: how much evidence exists in people, and how plausible the biological mechanism is. The rubric is published on How we check the science, and a grade never goes higher than the studies behind it allow.

Citation logs. Every page built or rebuilt since September 2026 has a citation log: each figure on the page, the source it comes from, and the sentence in that source that supports it. A figure that cannot be found in its source is cut. Older articles in Glow foods are being brought up to the same standard.

Dates. An article's modified date changes only when its content changes in substance.
