Sunscreen Solar Power Plant

Are there natural sunscreens derived from plant extracts?

There are also some natural sunscreens derived from plant extracts that act as the filters against UV irradiation. These natural compounds such as flavonoids, polyphenols, and carotenoids have aromatic rings and/or conjugated structures to absorb UV and diminish sunburn (L. Li et al., 2023).

Are natural sunscreens based on plants?

Besides studies on plants, other natural materials such as mycosporines 90, lignin 91 and green algae such as Klebsormidium fluitans 92, 93 were also analysed for their potential photoprotective activity and have become natural-based sun filters for sunscreens.

Which natural extracts enhance SPF of sunscreens?

Other natural extracts that enhance SPF of sunscreens are shown in Table S6. A sunscreen formulation consisting of 0.9–2.5 % w/w melatonin and 5.6–10 % w/w pumpkin seed oil (test formulation, while the control without antioxidants called challenge formulation) was prepared and assessed .

Are natural UV filters the future of sunscreen?

Plant compounds with aromatic rings usually show a broader absorption spectrum covering a wavelength range of 200–400 nm. Botanical ingredients used as UV filters also usually exhibit strong antioxidant properties. Therefore, these natural products are more advantageous as UV filters and are likely to be the future of sunscreens.

Are plant-derived photoprotectants a natural alternative to synthetic sunscreens?

Although constrained by their limited capacity in absorbing UVR and their inability to be spread in large-scale sunscreen cosmetic applications, plant-derived photoprotectants are increasingly being adopted as a natural alternative to synthetic sunscreens (He et al. 2021).

Do plant-based cosmetics protect the skin against solar radiation?

In addition to their antioxidant properties, plant-based cosmetics protect the skin against solar radiation because they contain polyphenols such as flavonoids and carotenoids. Therefore, this study aims to present a review of plant species commonly used in sunscreens to protect the skin against damage due to sunlight exposure.
