Skin aging is one of most visible ageing process which occurs constantly in our skin organ. According to the Clinical Centre of Nis, certain plant extracts may have the ability to scavenge free radicals, to protect the skin matrix through the inhibition of enzymatic degradation, or to promote collagen synthesis in the skin, affect skin elasticity and tightness(a). Other suggested that free radicals induced domino effects in production of reactive oxygen species, can react with DNA, proteins, and fatty acids, causing oxidative damage and impairment of antioxidant system, leading injuries damage regulation pathways of skin, including wrinkles, roughness, appearance of fine lines, lack of elasticity, and de- or hyperpigmentation marks(b).
The degradation of the epidermal and dermal layers of the extracellular matrix (ECM), the non-cellular component present within all tissues and organs, such as UV Exposure, decline of lysosomal/endosomal cathepsin K, S and V activity(c) as well as environment factors such as irregular dryness, dark/light pigmentation, sallowness, severe atrophy, telangiectases, premalignant lesions, laxity, leathery appearance and deep wrinkling, etc., cause modification of the surface of skin and the physical properties of that lead to skin aging. Certain foods have been found to be effective in protect the skin against natural aging, including green tea and garlic.
Date palm kernel extract
Date palm tree is a genus of Phoenix, belonging to the family Arecaceae, native from lands around Iraq. According to Vincience Research Center Date palm kernel
extract, in the study of 10 Ten healthy women volunteers, between the ages of 46 and 58 years, applied
the cream formula with 5% date palm kernel or placebo on the eye area twice a day for 5 weeks,
application of date palm kernel reduced the total surface of wrinkles by 27.6% (p = 0.038), the depth of
wrinkles by 3.52% (p = 0.0231). These results are statistically significant and were clinically confirmed
where visual improvement was seen in 60% of the volunteers treated(31).
