The waves of seawater will reflect strong light and will also be reflected by the beach, resulting in stronger ultraviolet rays at the seaside. As we all know, the pigmentation caused by excessive ultraviolet rays and strong ultraviolet rays at the seaside makes it easier for the beach to get tanned.

After tanning, you can use the following whitening tips:
1. Wash your face with a little vinegar once in the morning and once in the evening. This is a folk prescription, but it works well. I tried. It can whiten skin and remove acne, but you can't put too much vinegar. Of course, you can't put too little vinegar. Too little vinegar has no effect, and vinegar accounts for about one fifth.
2, eat more fruits and vegetables, fruits and vegetables are rich in adequate vitamins and protein and various nutrients, such as vitamin C and iron can make people's skin whiter and redder.
