The Complete Guide to Tanning Capsules: Everything You Need to Know Before Choosing a Beta-Carotene Supplement

Achieving a bronzed, even, and healthy-looking complexion is one of the most widespread cosmetic goals across southern Europe and beyond. At the same time, overexposure to sunlight remains the leading cause of premature skin ageing: according to photo dermatology research, ultraviolet radiation is responsible for approximately 80% of the visible signs of skin ageing, including wrinkles, dark spots, and loss of elasticity.

Against this backdrop, oral beta-carotene and carotenoid supplements have gained real traction as an alternative or complement to sun-based tanning. The concept is far from new; carotenoids were studied as skin-accumulating pigments capable of influencing skin tone and oxidative resistance as far back as the 1980s. What has changed dramatically, however, is the sophistication of the formulations available today. The best products now combine natural beta-carotene with patented botanical extracts, complementary antioxidants, and skin-hydrating actives to deliver a far more comprehensive effect.

Tanning capsules are worth considering for anyone looking to prepare their skin ahead of a holiday, extend a summer tan into the autumn months, reduce the likelihood of sunburn, or simply maintain a healthier, more luminous complexion year-round. They are also of particular interest to people who prefer to avoid frequent use of sunbeds or cosmetic self-tanning products.

In this guide, we explain what beta-carotene and carotenoids are, how they work in the skin, what the science says, and what criteria matter most when selecting a quality supplement. At the end, you will find our comparison of the four most popular products on the UK market, evaluated against strict criteria.

Carotenoids are fat-soluble plant pigments — the compounds responsible for the yellow, orange, and red colours in foods like carrots, tomatoes, melons, and peppers. Beta-carotene is the most studied of them all. The body converts it into vitamin A only in the amount it needs, which makes it a much safer option than synthetic retinol, with no risk of vitamin A toxicity from overconsumption¹.

Other carotenoids relevant to skin health include lycopene (found mainly in tomatoes), lutein (abundant in dark leafy greens), and astaxanthin (derived from microalgae). Each has its own antioxidant profile, and they tend to work better together than in isolation.

How beta-carotene acts on the skin

When taken regularly, beta-carotene gradually accumulates in the outer layers of the skin, lending it a subtle golden tone that helps intensify a natural tan. The effect builds over time and varies depending on dose, duration, and individual skin type.

Beyond aesthetics, carotenoids serve an important protective function. UV radiation triggers the production of free radicals in the skin, which damage cells and accelerate ageing. Carotenoids help neutralise these free radicals, reducing oxidative stress and supporting the long-term health of skin cells².

It is worth noting that the EFSA has officially recognised health claims for several nutrients commonly found in tanning supplements: copper for normal skin pigmentation, vitamin A for the maintenance of normal skin, vitamin C for collagen formation, and various vitamins and minerals for protection against oxidative stress³.

The role of lycopene  

Lycopene is the most abundant carotenoid in human blood plasma. Research suggests it plays an active role in protecting the skin against UV damage; interestingly, lycopene levels in the skin drop faster than beta-carotene levels when exposed to oxidative stress, pointing to its role as a first-line antioxidant defence⁴.

Astaxanthin and lutein: high-potency antioxidants

Astaxanthin, sourced from Haematococcus pluvialis microalgae, has one of the highest ORAC (Oxygen Radical Absorbance Capacity) values of any natural antioxidant and has been studied for its benefits on skin hydration, elasticity, and UV damage reduction⁵. Lutein, meanwhile, accumulates throughout the skin and acts as both a blue-light filter and an antioxidant, with studies pointing to its role in broader photoprotection⁶.

The dietary supplement market is full of claims that do not always align with the scientific evidence. There are also widespread popular beliefs that lead people to dismiss these products before learning the facts. We address the three most common myths and the evidence that corrects them.

Myth 1: "Tanning capsules will turn my skin orange"

This is probably the most widely held concern — and it has some basis in fact. Consuming very large quantities of beta-carotene, well above the recommended doses, can give rise to a condition called carotenoderma: a yellowish or orange discolouration of the skin, most visible on the palms of the hands and the soles of the feet. However, this effect is entirely reversible once the dose is reduced, and it disappears within a matter of weeks⁷.

Quality supplements are formulated with carefully calculated doses designed to produce a natural, gradual aesthetic effect without triggering carotenoderma. The key is to respect the recommended daily intake and to choose products with an appropriate beta-carotene concentration.

Myth 2: "These capsules mean I don't need sunscreen"

This is a potentially dangerous misconception. Beta-carotene and other carotenoids can contribute to strengthening the skin's internal defences against UV-induced oxidative stress, but they do not function as a sunscreen. They in no way replace the use of a broad-spectrum topical sun protection factor. Dermatologists are unanimous on this point: anyone planning to expose their skin to the sun should apply an appropriately rated sunscreen, regardless of what supplements they are taking.

Beta-carotene supplements should be understood as an internal complement that can help prepare the skin, intensify tanning, and prolong its effects, always in combination with appropriate topical sun protection.

Myth 3: "All beta-carotene supplements are the same"

Far from it. The quality of a beta-carotene supplement depends on multiple factors: the source of the active ingredient (chemically synthesised beta-carotene versus natural beta-carotene from microalgae such as Dunaliella salina); the presence of complementary ingredients with clinical backing, such as patented botanical extracts, standardised antioxidant compounds, and skin-hydrating actives; the bioavailability of the ingredients in the chosen dosage form; and compliance with strict manufacturing standards.

A supplement containing only synthetic beta-carotene alongside several unnecessary additives is simply not comparable to a multi-active formula with patented ingredients, produced under certified GMP and HACCP conditions. The difference in terms of results and safety can be very significant.

Fact 1: A patented melon extract Holimel® has shown measurable results in clinical studies

Holimel® is a patented extract of sweet melon (Cucumis melo L.) with a high concentration of superoxide dismutase (SOD), one of the most potent antioxidant enzymes produced by the body. A study published in the journal Nutrients examined its effects in healthy adults exposed to UV radiation and observed a 63% increase in the production of antioxidant enzymes in the skin and a 16% improvement in the skin's resistance to sunburn compared with the placebo group⁸. These findings support its use as a reference ingredient in oral tanning formulas.

Fact 2: Oral hyaluronic acid improves hydration and wrinkles from the inside out

Although hyaluronic acid is widely known as an ingredient in topical creams and serums, its use as an oral supplement has also been the subject of rigorous investigation. A double-blind, randomised, placebo-controlled study published in Nutrients in 2021 showed that oral hyaluronic acid supplementation over 12 weeks significantly reduced the visible appearance of wrinkles, increased skin hydration in the outer skin layer, and decreased transepidermal water loss⁹. This explains why the best tanning supplements include this ingredient in their formulations.

Fact 3: Carotenoids are absorbed much better in the presence of fat

Since carotenoids are fat-soluble compounds, their absorption at the intestinal level improves markedly when they are consumed alongside a small amount of dietary fat. This has practical implications: supplements should be taken after a meal containing some fat to maximise the bioavailability of the active ingredients. Some manufacturers take this factor into account and include small quantities of vegetable oils in their formulation or use micellised forms to optimise absorption.

The tanning supplement market has grown considerably in recent years, and the offer is wide and highly varied. Below are the most important criteria to consider before making a purchase.

• Source of beta-carotene: Prefer natural beta-carotene obtained from microalgae (Dunaliella salina), which also delivers a broader range of synergistic carotenoids and has superior bioavailability compared with synthetic beta-carotene.

• Presence of complementary ingredients: The best supplements combine beta-carotene with lycopene, lutein, astaxanthin, hyaluronic acid, and a vitamin and mineral complex (vitamins C, E, B2, copper, and selenium). Look for patented ingredients with scientific backing, such as Holimel®, AstaPure®, or FloraGLO®.

• Adequate dosage and bioavailability: Verify that the doses of the key ingredients are in line with those used in clinical studies. Excessively low doses may be ineffective.

• Dosage form: Capsules are generally preferable to tablets for fat-soluble ingredients, as they typically allow for better absorption.

• Formula purity: Avoid products that contain artificial colourings, unnecessary preservatives, sweeteners, or low-quality fillers. A clean formula reflects genuine respect for the consumer.

• Allergen-free status: Verify that the product is free from gluten, lactose, and other common allergens, particularly if you have food sensitivities.

• Manufacturing certifications: Products manufactured under GMP (Good Manufacturing Practice) and HACCP standards offer additional quality, safety, and hygiene guarantees. European production is preferable.

• Return policy: A generous return policy signals the manufacturer's confidence in their own product. The longer the period, the better.

To help you make a well-informed decision, we analysed the four most popular products on the UK market using strict criteria: ingredient quality, estimated effectiveness, value for money, customer satisfaction, return policy, and manufacturer transparency. The results of our comparison follow.
