Summer skin protection: the trend of oral sun protection

Published: 9-Jul-2025

Seppic’s SEPIBLISS offers clinically proven antioxidant and anti-inflammatory defence against UV damage

As summer approaches, consumers are seeking ways to protect their skin from the sun’s harmful effects. According to Grand View Research, the global sun care cosmetics market size was valued at USD 8.5 billion in 2022 and is expected to expand at a compound annual growth rate (CAGR) of 8.3% from 2023 to 2030¹. This shift is not only evident in topical sunscreen but also in the growing interest in ingestible supplements that offer internal skin protection².

Why is the demand for UV protection growing?

  1. Rising awareness of ultraviolet radiation skin damage: Increased consumer understanding of the harmful effects of UV radiation, including skin damage, premature aging, hyperpigmentation and even cancer, has led to a surge in demand for protective products³.

  2. Consumers' interest in natural products: There is a growing preference for products formulated with natural ingredients and clean-label formulations as consumers are more conscious about the ingredients they are ingesting and putting on their skin.

  3. The In & Out trend: Topical sunscreen remains the gold standard for sun protection, providing direct defense against UV damage. However, even if they should not be relied upon as the only method of sun protection, incorporating oral sun protection into a daily routine with topical sunscreen can effectively enhance skin protection for optimal results. The combination of oral supplementation “in” with topical sunscreens “out” is gaining traction as it addresses UV damage both internally and externally.

  4. Convenience and ease of use: Sun protection supplements can be seen as more convenient than applying topical products, as these are resistant to sweat and water. Moreover, consumers are interested in the longer-lasting effects of supplements compared to topical sunscreen.

  5. Multifunctional benefits: Sun protection supplements can address multiple skincare needs and concerns such as aging, hydration and skin sensitivity. Indeed, according to Mintel, 42% of suncare and skin protection consumers in the US seek anti-aging claims, and 43% seek sensitive skin-safe claims⁴.


Which is the best oral sunblock ingredient for supplements?

The ingredients of choice in suncare dietary supplement formulas are those with antioxidant and/or anti-inflammatory properties, making the skin more resilient to the damage caused by the sun. These include:

  1. Carotenoids such as lycopene, beta-carotene and astaxanthin:

    • Lycopene: Found in tomatoes and other red fruits, lycopene is a potent antioxidant that may enhance the skin’s ability to prevent sunburn.

    • Beta-carotene: A precursor to vitamin A, beta-carotene has been shown to improve skin resistance to UV-induced erythema.

    • Astaxanthin: Found in microalgae and seafood, renowned for its antioxidant properties, thus reducing oxidative stress and protecting skin cells from UV damage.

  2. Vitamins C and E: Essential antioxidants that can help combat free radicals caused by UV exposure. Vitamin C also supports collagen synthesis.

  3. Flavonoids: A diverse group of polyphenolic compounds naturally found in green tea and a wide array of fruits. Studies suggest their antioxidant and photoprotective properties.


Other key ingredients of ingestible sun supplements include botanical extracts. While options exist, it is particularly important to rely on good quality, standardised and science-backed ingredients for such applications.

Summer skin protection: the trend of oral sun protection

In response to the growing consumer demand for natural, effective and convenient solutions to support skin protection, Seppic developed SEPIBLISS™, a patented nutraceutical ingredient designed to protect all skin types against external aggression. SEPIBLISS™ is derived from coriander seed oil and does not contain any solvents, additives or preservatives, aligning with current consumer expectations.

SEPIBLISS™ efficacy is supported by a total of three gold standard clinical trials. The most recent clinical research involved 99 healthy women aged between 35 and 65 years old, presenting signs of aging, who were supplemented with 100 mg/day or 200 mg/day of SEPIBLISS™ Oil for a period of two months. The clinical study demonstrated the ingredient’s action on skin barrier reinforcement, with a 9% significant reduction in transepidermal water loss after 1 month of supplementation with 200 mg/day. Similar results were observed with the lower dose. Moreover, when the skin of volunteers was exposed to UVA and UVB, a significant 18% decrease of skin erythema was observed after 2 months of supplementation with a daily dose of 200 mg, showing the ingredient’s ability to mitigate the negative effects of UV exposure on the skin.

Importantly, SEPIBLISS™ improved skin appearance with significant results starting at 2 weeks of supplementation with a daily dose of 100 mg or 200 mg. After 2 months, a 9% decrease in crow’s feet wrinkles depth was observed. Similarly, skin firmness was also improved.

SEPIBLISS™ is also suitable for consumers with sensitive skin, as shown in two clinical studies⁵.

SEPIBLISS™ efficacy is attributed to a demonstrated dual mechanism of action:
Antioxidant action: Demonstrated reduction in skin lipid peroxidation following UV exposure.
Anti-inflammatory action: Protection from excessive inflammation induced by UV exposure⁶.

The compelling evidence from multiple gold-standard clinical trials firmly establishes SEPIBLISS™ as a powerful ally in the fight against photoaging. Its ability to reinforce the skin barrier, significantly reduce UV-induced erythema, help achieve a youthful appearance by diminishing wrinkles and enhancing firmness, coupled with its dual antioxidant and anti-inflammatory mechanisms, underscores its comprehensive protective action against the damaging effects of sun exposure.

Furthermore, its suitability for sensitive skin makes SEPIBLISS™ an ideal ingestible solution for a broad range of consumers seeking to proactively combat the visible signs of photoaging.

Thanks to its two grades, SEPIBLISS™ can be easily formulated into:
Reference formats: Hard capsules, softgels, powders, sticks
Emerging and trendy formats: Gummies, liquids, chocolate bites, liposomal solutions
