When you drink enough water, the cells in every part of your body get hydrated through the blood. The skin, being the largest organ in the body, also gets hydrated, even as the impurities and toxins get flushed out at the cellular level.
4 Benefits of drinking water for your skin:
1. Improves Skin Tone:
Drinking enough water helps the body to flush out toxins while giving you healthier skin. Studies have revealed that drinking just two cups of water  can increase blood flow to the skin which gives it an even tone.
2. Prevents Premature Aging:
Staying hydrated helps increase elasticity in the skin as it stays moisturised for longer. Heightened elasticity in the skin implies delayed sagging of the skin and no premature appearance of fine lines and wrinkles.
3. Faster Healing:
If you have been out in the sun and got sunburnt, drinking water can fasten the healing process.
4. Reduces Puffiness:
When the skin looks puffy, it is actually retaining water to protect you from dehydration. This occurs when you don’t drink enough water. Staying hydrated will reduce swelling and puffiness in your face
