First, read the English article below.

. Smiling brightens up your face and allows your inner beauty to shine through. It gives the impression of happiness and confidence, while also making you more attractive to others. Smiling more often will help you to look your best, regardless of whether you're wearing makeup or not. A healthy glow can transform your appearance, making your skin appear more radiant and your complexion smoother and more even-toned. If you can achieve a tan naturally, while also wearing protection, that's great. However, tanning beds and other options like these are expensive and occasionally cause skin cancer, so try a spray-on tan (good quality—you don't want to look fake) or for your face, bronzer for an extra little sun-kissed glow. Look for facial moisturizers which will slowly build up a natural-looking tan and leave you looking sun-kissed, no matter the weather. Looking and feeling healthy has a lot to do with what you put into your body. Skin, especially, can be affected by a poor diet and healthy skin is essential to looking good without makeup. Try to cut out as many greasy, fatty, sugary foods as possible and load up on fruits, vegetables, whole grains and lean meats instead.  Remember to drink plenty of water to flush out your system, keep skin looking healthy and prevent you from feeling bloated. Take a vitamin supplement if you feel you are not getting all of your daily requirements from your diet alone. Vitamins A, C and E are all particularly beneficial for the skin. True beauty shines from within, so stop believing that you need your mascara to feel confident and start believing in you. Stand up tall, with your shoulders back and your chin up. Make eye contact with people and smile frequently. Remember that makeup is simply a tool used to emphasize certain features—your natural beauty has been there all along.
