“…Phytochemicals from plant, such as phenolics and flavonoids, are considered as a conjugated aromatic system with the capacity to absorb UV light [22]. Punica granatum extract has widely applied as an oral supplement in skin care products, due to its potent photoprotection through the inhibition of free radicals or erythema and burning [23]. In this study, pomegranate peel expressed anti-UV capacity, with the SPF value higher than a commercial sunscreen (Dermatone) at the enzyme con-centration 1000 IU and 10% [24] .…”

The purpose of this study was to evaluate the antioxidant, antibacterial, and anti-UVB of three kinds of fermented fruit peel extracts by pectinase enzyme, including pomegranate, pomelo, and banana peel. The antioxidant was evaluated by the DPPH (2,2-Diphenyl-1-picrylhydrazyl) free radical scavenging method. Antibacterial activity against Escherichia coli and Staphylococcus aureus was assessed by disk diffusion assay, and the photoprotective activity was measured using a photospectrometric method. The results revealed that pomegranate peel extract at 3000 IU/g peel exhibited potent free radical scavenging property against DPPH, with the smallest IC50 value at 0.18%, which was better than that of pomelo peel extract at 55.79%. Furthermore, the results suggested that the pomegranate peel extract also exhibited antibacterial activity against E. coli better than pomelo peel extract, but none of the three samples shows the antibacterial capacity against S. aureus. Moreover, 10% pomegranate peel extract also expressed the strongest anti-UVB activity, with an SPF value of 36.582. The research demonstrates pomegranate peel’s bioactivity potential for further experiments.

Exposure to sun radiation leads to higher risk of sunburn, pigmentation, immunosuppression, photoaging and skin cancer. In addition to ultraviolet radiation (UVR), recent research indicates that infrared radiation (IR) and visible light (VIS) can play an important role in the pathogenesis of some of these processes. Detrimental effects associated with sun exposure are well known, but new studies have shown that DNA damage continues to occur long after exposure to solar radiation has ended. Regarding photoprotection strategies, natural substances are emerging for topical and oral photoprotection. In this sense, Fernblock®, a standardized aqueous extract of the fern Polypodium Leucotomos (PLE), has been widely administered both topically and orally with a strong safety profile. Thus, this extract has been used extensively in clinical practice, including as a complement to photodynamic therapy (PDT) for treating actinic keratoses (AKs) and field cancerization. It has also been used to treat skin diseases such as photodermatoses, photoaggravated inflammatory conditions and pigmentary disorders. This review examines the most recent developments in the clinical application of Fernblock® and assesses how newly investigated action mechanisms may influence its clinical use.

“…This plant is known as green tea and exhibits antioxidant, antiinflammatory, immunomodulatory, and chemopreventive properties. Punica granatum (pomegranate), Grapeseed, grape peel and even red wine (Resveratrol), Curcuma longa (Curcumin), Silybum marianum (Silymarin) and other plant extracts have been shown photoprotective activity (Torres, Luk, Lim, 2020). On the other hand, mycosporine-like amino acids show antioxidant, antiage and photoprotective activities, they are produced by fungi, algae and cyanobacteria (Lawrence, Long, Young, 2017).…”

Skin is the largest and heaviest organ in the human body also one of the most important and act as a barrier that separates our organism from the environment. The nature of this cover is physical, chemical, and immunological. It controls the flow of substances between the environment and the body. Skin pH between 5-7 works as a chemical barrier that helps to maintain its integrity and natural microbiota (Dragicevic, Maibach, 2015).Langerhans cells, dermal dendritic cells and macrophages are specialized skin cells that make the skin an immunecompetent organ (Dragicevic, Maibach, 2015;Wiznia, Elbuluk, 2017). The skin carries out metabolic functions like vitamin D synthesis. Furthermore, thermo-regulation, excretion, endocrine and sensitivity are other functions performed by the skin. (Dragicevic, Maibach 2015) The histological structure of the skin consists of a complex architecture that has three fundamental layers: epidermis, dermis and hypodermis (Figure 1A). The epidermis is the outermost layer. (Wiznia, Elbuluk, 2017) The main constituent cells of this layer are keratinocytes corresponding to 95 %, the remaining 5 % of the cells are melanocytes, Langerhans cells and dermal dendritic cells (Dragicevic, Maibach, 2015;Wiznia, Elbuluk, 2017) Melanocytes fulfill the production of melanin, which is the main endogenous defense of the skin to protect us against UV-radiation (UVR) (Norman, Menendez, 2008). The dermis is the second layer of the skin and is thicker
