How dietary carotenoids, vitamin C-driven collagen synthesis, and multi-source antioxidants create measurable skin improvements
Our Skin Glow Shots are built around three scientific principles, each supported by clinical evidence: beta-carotene for UV protection and cell renewal, vitamin C for collagen synthesis, and multi-source antioxidants for cellular defense. Here's the deep dive.
Beta-Carotene: Your Skin's Natural Sunscreen From Within
Beta-carotene is the orange-red carotenoid pigment abundant in carrots (the richest common dietary source) and beetroot. Your body converts it to vitamin A (retinol), essential for skin cell differentiation, renewal, and repair. But beta-carotene does something extraordinary beyond vitamin A conversion.
Research published in the American Journal of Clinical Nutrition demonstrated that consistent dietary beta-carotene intake over 10+ weeks builds up levels in your skin tissue, providing measurable protection against UV-induced erythema (sunburn). It literally functions as an internal sunscreen. A separate study published in Dermatology found that 30mg/day of beta-carotene supplementation not only prevented photoaging but actually repaired existing UV damage and increased type I procollagen gene expression in human skin — procollagen is the precursor to collagen.
This doesn't replace topical sunscreen. But it adds a layer of internal protection that topical products can't provide. Our Skin Glow shot delivers concentrated beta-carotene from both carrots and beetroot, providing this dual protection daily.

Vitamin C and Collagen: The Essential Partnership
Collagen constitutes 75% of your skin's dry weight. It's the structural protein that keeps skin firm, plump, and elastic. After age 25, your body's collagen production declines by approximately 1% per year — which is why skin gradually loses firmness.
Vitamin C is an absolute requirement for collagen synthesis. It serves as a cofactor for prolyl hydroxylase and lysyl hydroxylase — the two enzymes that stabilize collagen's triple helix structure. Without vitamin C, these enzymes can't function, and collagen production stops (which is why scurvy causes skin and gum breakdown).
A laboratory study confirmed that vitamin C induces a dose-dependent increase in collagen type I deposits by human fibroblasts — more vitamin C literally means more collagen production, up to a saturation point. A 2024 randomized, double-blind, placebo-controlled trial went further: dietary vitamin C supplementation showed notable enhancements in dermis density, skin texture, and reduction in wrinkle severity compared to placebo. This was a human clinical trial, not just lab research.
Our Skin Glow shot delivers vitamin C from amla — one of nature's richest sources (600-700mg per fruit, 10-20x more than an orange). Unlike synthetic ascorbic acid supplements, amla's vitamin C exists within a natural matrix of tannins and bioflavonoids that may enhance stability and absorption.
The Multi-Source Antioxidant Advantage
Free radicals — generated by UV exposure, pollution, stress, and normal metabolism — are the primary drivers of skin aging. They damage DNA, break down collagen and elastin, and trigger inflammatory cascades that accelerate aging.
Our Skin Glow shot delivers antioxidants from four different sources, each providing different classes of protective compounds: amla provides polyphenols (gallic acid, ellagic acid, quercetin), beetroot provides betalains (which scavenge free radicals and prevent DNA damage), carrot provides carotenoids (beta-carotene, alpha-carotene, lutein), and honey provides flavonoids and phenolic compounds. A study of 4,025 women found higher antioxidant intake (especially vitamin C) was directly associated with less wrinkled appearance and less senile dryness. A review in Nutrients confirmed that carotenoids, polyphenols, and vitamins protect skin against oxidative stress and reduce the risk of photoaging and skin cancer.
The advantage of multiple antioxidant sources over a single supplement: different antioxidants work in different cellular compartments and against different types of free radicals. Beta-carotene is fat-soluble (protecting cell membranes), vitamin C is water-soluble (protecting intracellular fluid), and polyphenols work across both. Together, they provide comprehensive protection that no single antioxidant can match.

Juicing actually increases beta-carotene bioavailability compared to eating raw carrots, because it breaks the plant cell walls. However, beta-carotene is fat-soluble — consuming the shot with a meal containing some fat enhances absorption.
The vitamin C → collagen pathway is one of the most well-established in biochemistry. A 2024 RCT confirmed dietary vitamin C supplementation measurably improves dermis density and wrinkle severity. So yes — if your juice provides sufficient vitamin C (amla delivers 600-700mg per fruit), it genuinely supports collagen production.
Skin renewal cycles take ~28 days. Beta-carotene needs 10+ weeks to accumulate in skin tissue. Most people notice improvements in radiance at 4-6 weeks, with UV protection building over 10+ weeks of consistent daily intake.
Different approach. Collagen supplements provide pre-formed collagen peptides. Our shots provide the raw material (vitamin C) your body needs to produce its own collagen, plus antioxidants that protect existing collagen from degradation. Ideally, both complement each other.
