Thanks to its high content of vitamin C and citric acid, lemon can help brighten the skin and remove accumulated dead skin cells.
According to Cleveland Clinic, vitamin C is a powerful antioxidant, helping to reduce the effects of free radicals and supporting even skin color. Citric acid in lemon acts as a mild exfoliant, helping to remove dark skin, thereby promoting the process of regenerating new cells.
One of the simple ways is to dilute lemon juice with water in a 1:1 ratio, then use a cotton pad to soak and gently apply it to the dull skin area. Leave it for about 5-10 minutes, then wash it off with warm water and apply moisturizer. Doing it 2-3 times a week can help improve skin brightness over time.
Dermatologist Joshua Zeichner (USA) said that vitamin C-rich ingredients can help brighten skin and improve pigmentation if used properly. However, he also recommends not using lemon directly at high concentrations, as strong acidity can cause irritation or make skin more sensitive to sunlight.
Experts emphasize that lemon should only be used as a supporting measure. Users need to test on a small area of skin before applying it widely and always combine moisturizing and sun protection to protect the skin. When used correctly, lemon can become a natural, simple solution to help improve dull skin and bring brighter skin.
