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.
Mango tree is a flower plant of genus of Mangifera, belonging to the
family Anacardiaceae, native to the subtropical and tropical southeast
Asia. The
Beside exerting its antioxidant with anti-inflammatory and immunomodulatory activities, mango extract also showed to inhibit wrinkle formation and damage to collagen fiber against UVB-induced skin aging
in hairless mice(12). Polyamine, a major chemical constituent of mango
and other plants may be potential target for reduced aging skin as the
level of spermidine was maximal in 10-week-old mice and markedly reduced
in 26-week-old mice(13).
