In recent studies, lemon peel has been shown to be effective in skin lightening due to its antioxidant, exfoliating, and dark spot fading properties.
Contains lots of vitamin C and flavonoids
Lemon peel contains a large amount of vitamin C - a powerful antioxidant that helps protect the skin from the harmful effects of UV rays and prevents the formation of melanin (pigment that causes skin darkening). Research from the Journal of Clinical and Aesthetic Dermatology shows that vitamin C has a natural skin lightening effect by inhibiting the formation of melanin, helping to reduce dark spots and even out skin tone. Besides vitamin C, lemon peel also contains flavonoids, especially hesperidin and eriocitrin, these compounds help reduce inflammation and protect skin cells from damage caused by free radicals, a major cause of skin aging and darkening.
Exfoliate and cleanse skin
Lemon peels are naturally acidic, which helps remove dead skin cells on the surface of the skin, making the skin brighter and smoother. The citric acid in lemon peels has a gentle exfoliating effect without damaging the skin. Removing dead cells makes it easier for the skin to absorb nutrients, thereby supporting the skin regeneration process and brightening the skin.
Ability to fade dark spots and melasma
One of the outstanding effects of lemon peel is its ability to fade dark spots, melasma and freckles. The antioxidants in lemon peel, especially vitamin C, help lighten dark skin areas, thereby evening out skin tone. Lemon peel extract has the effect of brightening the skin and reducing the appearance of brown spots, thanks to its ability to inhibit the enzyme tyrosinase, an important enzyme in the synthesis of melanin. Therefore, regular use of lemon peel can help lighten the skin naturally.
With its outstanding benefits, lemon peel is now used in many beauty products, from skin creams to skin lightening masks. Organizations such as the American Academy of Dermatology recommend using products containing vitamin C and lemon peel extracts to improve skin pigmentation. However, it should be noted that lemon peel is highly acidic, so when using directly on the skin, it should be diluted or tested on a small area of skin to avoid irritation.
