Having a clear and smooth skin of the Korean Stars is now the ambition of many women. In order to get the flawless skin, often mentioned the importance of drinking lots of water.
Enough water is believed to be effective to make skin supple and glowing look. Celebrities also call drinking water as their beautiful secret.
Although drinking enough water is essential for health, there is little scientific evidence to prove that drinking water is beneficial to the skin.
A study from Clinics in Dermatology found, there is only one study that concluded the long-term benefits of water consumptions on skin health.
Published in the International Journal of Cosmetic Science, the team of researchers mentioned 2.25 liters of water daily for 4 weeks will increase skin density and thickness. But the results of his research are considered ambiguous.
Another study conducted by a team from the University of Missouri-Columbia, USA, showed, drink 500 ml of water will launch blood circulation to the skin. But, this also can not prove the appearance of the skin so much better.
"The outer layer of the skin, the stratum corner, is designed to prevent water loss on the skin, and studies have shown that less water-drinkers improve their water consumption patterns, improve skin thickness and better hydrate the skin," says Fayne L-Frey dermatology and skin functional experts.
However, drinking enough water did not improve the appearance of the skin. It depends on the skin's ability to hold water.
"In healthy individuals with normal skin thickness, drinking enough water is not proven to prevent wrinkles or other signs of aging," Frey said.
Dermatologists say that it is best to apply moisturizer to the skin because it has a formula to prevent water evaporation from the skin. Choose also humectant moisturizing products (the content that makes water form a layer on the skin).
"Drinking plenty of water will only affect the skin if we are very dehydrated, and besides, the skin is hydrated in two ways, natural oil production or cream and lotions applied," says Joel Schlessinger, a dermatologist.
Consumption of enough water only affects the deep tissue, not to improve the skin condition.
"Skin appearance is influenced by many factors, ranging from hormonal, genetic, lifestyle, diet, exercise, to the choice of skin-care products," he said.
