Introduction
Protecting the skin against ultraviolet (UV) radiation is one of the key elements of dermatological prevention. Although creams with SPF filters are commonly used, the so-called photoprotection from the inside, i.e. the use of bioactive ingredients in the diet and supplements that can support the skin’s natural defense mechanisms. In recent years, scientific research has confirmed that an adequate supply of antioxidants, carotenoids and polyphenols can reduce the negative impact of UV radiation on cellular structures and skin proteins.
UV radiation and its effect on the skin
UV radiation is divided into three main ranges:
- UVA (320–400nm) – penetrates deep into the dermis, accelerates collagen degradation, induces the formation of free radicals and promotes photoaging.
- UVB (290–320nm) – reaches the epidermis layer, is responsible for sunburn and cell DNA damage.
- UVC (100-290nm) – is mostly absorbed by the atmosphere, so it is not an important factor in everyday exposure.
UV radiation causes oxidative stress, which causes the oxidation of lipids, proteins and nucleic acids. Matrix metalloproteinases (MMPs) are activated, collagen and elastin fibers are degraded and the risk of gene mutations increases.
Photoprotection mechanism from the inside
dietary supplements containing antioxidants and other bioactive substances work on several levels:
- Neutralization of free radicals – preventing oxidative damage caused by UV radiation.
- Stabilization of cell membranes – protection of lipids against peroxidation.
- Modulation of the inflammatory response – reducing the expression of inflammatory mediators (e.g. interleukins, TNF-α).
- Strengthening the skin’s immunity – improving the regenerative capacity of keratinocytes and fibroblasts.
Ingredients with proven photoprotective effect
Astaxanthin
Astaxanthin is a carotenoid with an exceptionally high antioxidant potential – according to research, it may be up to 500 times superior to Vitamin E in terms of its ability to quench reactive oxygen species (ROS). It inhibits lipid peroxidation and reduces erythema after exposure to UVB.
beta-carotene, lycopene, lutein
Carotenoids accumulate in the epidermis and dermis, where they absorb part of the radiation and neutralize ROS. Beta-carotene is a precursor of vitamin A, supporting epithelial regeneration processes. Lycopene has strong antioxidant properties, and lutein additionally filters blue light, which is important when the skin is exposed to high energy visible light (HEV).
vitamin c
Cofactor of proline and lysyl hydroxylases in the process of collagen synthesis. It supports the regeneration of vitamin e, reduces UV-induced inflammation and reduces DNA damage.
Vitamin E
It protects the lipids of cell membranes against oxidation, reduces inflammation in the skin after exposure to UV and works synergistically with vitamin C.
Green tea polyphenols
Catechins (EGCG) contained in green tea inhibit the formation of erythema, reduce DNA damage and modulate the activity of MMPs. They also have the ability to inhibit angiogenesis induced by UV radiation.
The role of antioxidants in protection against photoaging
UV radiation generates reactive oxygen species (ROS) in the skin, which damage collagen, elastin and lipids of cell membranes. This phenomenon leads to photoaging – loss of skin firmness, discoloration and deep wrinkles. Antioxidants found in dietary supplements can neutralize these free radicals before they cause damage. Products Calivitasuch as qProtect provides high-quality antioxidant ingredients, including astaxanthin, vitamin E, vitamin C and polyphenols, which support the skin’s natural defense mechanisms. Research shows that regular supplementation with antioxidants can reduce the intensity of redness after exposure to the sun and improve the overall condition of the skin, constituting an important complement to external protection in the form of SPF filters.
Supplements Calivita supporting photoprotection
Products Calivita combine ingredients with antioxidant, anti-inflammatory and skin regeneration supporting properties:
- glamUp Pure – contains a complex of antioxidants, including vitamins C and E, which protect skin cells against oxidative stress and support collagen synthesis.
- Full Spectrum – rich in vitamins and minerals, including beta-carotene and selenium, which plays a role in neutralizing free radicals by activating glutathione peroxidase.
- Omega 3 – EPA and DHA acids improve skin elasticity, reduce inflammation and limit water loss through the epidermis (TEWL), which increases the skin’s resistance to UV radiation.
- AC-Zymes – a probiotic supporting the intestinal microbiota, which indirectly affects the skin’s immunity and its ability to heal micro-damages caused by radiation.
The importance of a combined strategy – protection from the outside and the inside
No dietary supplement can replace sunscreens, but the synergistic effect of oral preparations and topical protection provides the best results. Photoprotection from the inside supports the body’s natural defense mechanisms and reduces cumulative skin damage that leads to photoaging and photocarcinogenesis over the years.
Summary
Long-term exposure to UV radiation requires a comprehensive approach to skin protection. Antioxidant-rich supplements such as produce Calivitacan support photoprotection from the inside by reducing oxidative stress, promoting tissue regeneration and modulating the inflammatory response. Combined with SPF filters and a healthy lifestyle, they constitute an effective preventive strategy against premature aging and skin damage.
