You read the label. You compare the ingredients. You check the doses against the research. But there is one question most people skip entirely: how much of what is on that label actually survives manufacturing and makes it into your body?
When it comes to carotenoid supplements -- the plant compounds that support your skin from the inside -- the answer depends heavily on format. And the difference between a well-made capsule and a heat-manufactured alternative is not subtle. It can mean the difference between a formula that delivers what it promises and one that lost half its potency before you ever opened the bag.
Here is what we think every informed consumer should know.
Heat Is the Enemy of Carotenoids
Carotenoids are powerful but sensitive compounds. Lycopene, astaxanthin, beta-carotene, lutein -- these are the same molecules that give tomatoes, salmon, and marigolds their vivid colors. They are also among the most clinically studied plant compounds for skin support.
But carotenoids degrade when exposed to high heat. This matters because many supplement formats -- particularly gummies -- require heat during manufacturing. The binding agents, gelatin or pectin bases, sweeteners, and flavors that hold a gummy together all need to be heated and molded into shape. That process exposes the active ingredients to temperatures that can break down carotenoid molecules before they ever reach you.
Research on heat degradation of carotenoids shows losses of 30 to 60 percent during thermal processing. That means a gummy listing a certain dose on the label may deliver only half -- or less -- of that amount in its final form.
Cold-process capsules avoid this entirely. Our capsules are manufactured without heat exposure, preserving 100 percent carotenoid integrity from raw ingredient to finished product. What is on our label is what is in the capsule.
What Else Is in There?
Format does not just affect potency. It also determines how many extra ingredients come along for the ride.
Gummy supplements need structure, flavor, sweetness, color, and shelf stability. That typically means 8 to 15 inactive ingredients -- things like sugar (usually 2 to 4 grams per serving), corn syrup, gelatin, citric acid, artificial or natural flavors, colorants, coatings, and preservatives. None of these contribute to the product's function. They exist to make the format work.
GLOW has three inactive ingredients: hypromellose (the veggie capsule shell), rice powder, and magnesium stearate. That is it. Zero grams of sugar. No flavors. No dyes -- the red-orange color of our capsules comes from the naturally occurring carotenoids themselves.
We believe your daily photonutrition ritual should deliver the compounds you are paying for, not a serving of candy with some actives mixed in.
Why Carotenoids Take 8 to 12 Weeks (and Why That Is a Good Sign)
One of the most common frustrations we hear about in the supplement space is the timeline. People start a new product, take it for two or three weeks, and wonder why nothing has changed.
With carotenoids, the timeline is not a flaw. It is the mechanism.
Unlike circulating antioxidants that enter your bloodstream, do their work, and get metabolized out, carotenoids physically accumulate in your skin tissue over time. They deposit into the epidermis and dermis, building tissue-level reserves that provide continuous, whole-body support. A meta-analysis of 7 clinical studies confirmed that beta-carotene builds measurable support that increases with each month of consistent use.
This is why peer-reviewed research on ingredients like those in GLOW consistently uses study durations of 8 to 12 weeks or longer. The compounds need time to reach meaningful concentrations in skin. Most people notice changes in 4 to 8 weeks, with full support developing over 8 to 12 weeks.
If a product claims to transform your skin in days, it is worth asking what is actually happening at the tissue level. Structural support that becomes part of your skin is fundamentally different from a temporary circulating effect -- and it takes longer to build for exactly that reason.
Provitamin A: The Safety Question Worth Understanding
Not all vitamin A in supplements is the same, and this is a distinction worth knowing.
Preformed vitamin A (retinol, retinyl palmitate) is already in its active form when you take it. Your body cannot regulate how much it absorbs, which means high doses can accumulate to potentially problematic levels.
Provitamin A -- specifically beta-carotene, which is what we use in GLOW at 6,000 mcg RAE -- works differently. Your body converts beta-carotene into active vitamin A only as needed. The conversion is self-regulated: when your body has enough, it simply slows down or stops converting. Excess beta-carotene is stored harmlessly or excreted. There is no toxicity risk at normal dietary supplement doses.
This is not a minor formulation detail. It is a deliberate choice we made based on the research, and it is one more reason we believe informed consumers deserve to understand what is in their supplements and why.
What This Means for Your Daily Ritual
We built GLOW as cold-process capsules with five clinically studied plant compounds -- lycopene, astaxanthin, beta-carotene, lutein, and annatto tocotrienols -- because we believe format is inseparable from function. The best ingredients in the world do not matter if they are degraded before they reach you.
Three capsules daily, taken with food containing healthy fats for optimal absorption, supported by a piperine absorption optimizer at the exact dose used in research. That is the full ritual.
We are not the flashiest option on the shelf. We do not taste like candy. But everything in the capsule is there for a reason, backed by peer-reviewed research, and preserved exactly as it should be.
For people who love the sun and care about their health -- that is what daily photonutrition should look like.
