Everglow was built around one idea: that what you drink can support how your skin looks and feels over time. Not as a replacement for skincare. Not as a miracle in a sachet. But as a daily source of compounds the research associates with antioxidant protection, collagen support, and skin health from the inside.
Here's what's actually in the blend — and what the science says about each ingredient.
Ceylon black tea: the foundation
Ceylon black tea — grown in Sri Lanka, one of the world's most renowned tea-producing regions — forms the base of Everglow. As a black tea, it undergoes full oxidation during processing, which develops its characteristic depth of flavour and transforms its polyphenol profile.
The primary antioxidant compounds in black tea are theaflavins and thearubigins — polyphenols produced during oxidation that are specific to black tea and not found in green tea. Research has found that some of the antioxidants identified in Ceylon tea are specifically linked to reducing collagen loss in the skin by preventing oxidative stress in the surrounding cells — and collagen is important for skin elasticity, preventing the appearance of wrinkles and keeping the skin taut and strong.
It's worth being clear about what this means in practice: antioxidants work by neutralising free radicals — unstable molecules generated by UV exposure, pollution, and metabolic processes that damage skin cells and accelerate visible ageing. Black tea is a meaningful dietary source of these compounds, though it is not the only one, and no single beverage overrides the cumulative effect of lifestyle, sun protection, and diet as a whole.
Ceylon black tea also contains caffeine — something worth knowing if you're sensitive to it or drinking later in the day.
Hibiscus: the antioxidant and the colour
Hibiscus brings both the deep crimson colour and a significant antioxidant contribution to Everglow's cup.
The hibiscus plant is rich in antioxidants including beta-carotene, vitamin C, and anthocyanin — the pigment responsible for its vivid red-purple hue. Anthocyanins are a class of flavonoids well-studied for their antioxidant and anti-inflammatory properties. Several studies show that hibiscus extract has significant antioxidant effects, with its flavonoids and vitamin C known to nourish the skin and reduce oxidation.
The skin-specific research on hibiscus is particularly relevant here. Hibiscus contains high levels of proanthocyanidins, a class of polyphenols that have been shown to protect collagen fibers from enzymatic degradation — and coupled with its naturally occurring vitamin C, hibiscus may not only help preserve existing collagen but also stimulate new collagen formation, improving skin elasticity and structure.
The honest caveat, as with all botanical ingredients consumed in tea form: the concentration of these compounds in a brewed cup will differ from the concentrated extracts used in clinical and cosmetic studies. The effect is real — the magnitude in a daily cup is more modest than a topical serum. Both can be part of the same approach.
Rosehip: vitamin C and collagen support
Rosehip — the small fruit that forms below the rose flower after it blooms — has one of the strongest research profiles of any ingredient in Everglow's blend when it comes to skin health.
Rosehips are among the highest food sources of vitamin C, containing more than many other fruits and vegetables — and vitamin C is critical for skin health as it builds collagen, provides antioxidant protection, and contributes to skin tone. A published review in Frontiers in Pharmacology confirmed that rosehips and vitamin C have indicated positive effects on collagen synthesis by enhancing its formation, and have also shown to lessen the depth of facial wrinkles.
The most cited human clinical study on rosehip and skin ageing is a 2015 randomized, double-blinded trial published in Clinical Interventions in Aging. Thirty-four healthy adults aged 35–65 were given either standardized rosehip powder or astaxanthin — a well-known anti-ageing supplement — for 8 weeks. The rosehip group showed statistically significant improvements in crow's-feet wrinkles, skin moisture, and elasticity by the end of the study.
As with all ingredients consumed in tea form, dried rosehip in an infusion will deliver these compounds at lower concentrations than a supplement dose. What a daily cup offers is a consistent, low-level source of these compounds over time — which is generally how dietary support for skin health is understood to work: not dramatically in one dose, but cumulatively as part of a routine.
Mixed dried fruits: flavour with benefits
Everglow also contains a blend of dried fruits — cherries, grapes, and apples — along with just a touch of artificial flavouring to enhance the blend's rich, fruity character.
The dried fruits themselves do bring something meaningful to the cup: cherries are rich in anti-inflammatory polyphenols, apples are an important source of polyphenols in the human diet and their consumption has been linked to the prevention of degenerative diseases, and grape skins in particular are a considerable source of bioactive substances including flavonoids, anthocyanins, phenolics, and resveratrol — attributed with antioxidant and anti-inflammatory effects.
In a blend context, these fruits contribute to the overall antioxidant load of the cup — but they're the supporting cast, not the headline. The primary functional contributors in Everglow are Ceylon black tea, hibiscus, and rosehip.
How it comes together
Everglow isn't a skincare product. It won't replace SPF, sleep, or a considered skincare routine. What it can do — consumed consistently as part of your day — is add a meaningful source of antioxidants, polyphenols, and collagen-supporting compounds through a ritual you already want to build.
The research on each of these ingredients points in the same direction: plants rich in antioxidants and vitamin C support the skin's ability to manage oxidative stress, produce collagen, and maintain elasticity over time. Everglow brings four of those ingredients together in one cup, formulated for skin and radiance, with nothing added for show.
That's a quiet contribution. But for skin, consistency is usually the point.
