It will take 2 to 3 months to see the whitening effect after washing your face with salt and vinegar.
1. Wash your face with salt water
Washing your face with salt water can help remove oil and cuticles on the face, and can help reduce blackheads.
For oily skin, just use salt and water. For dry skin, you can put a spoonful of water-soluble or weakly oily massage cream in the palm of your left hand, add half a spoonful of salt and an appropriate amount of water. Be careful not to apply the salt water around the eyes to avoid stains and damage to the conjunctiva.
2. Wash your face with vinegar and water
Washing your face with vinegar and water can increase the moisture and nutrition of skin cells, restore the luster and elasticity of the skin, soften the cuticle and whiten it. There is also sterilization.
The idea that vinegar can whiten comes from the fact that it has some bleaching properties. The main component of vinegar is acetic acid, and it also contains a small amount of amino acids, organic acids, sugars, and vitamins B1 and B2. Vinegar can also dissolve nutrients, such as calcium and iron in inorganic salts
Extended information:
Whitening is also a care project from the inside out. First of all, you must choose a set of whitening products that suit you. Because the whitening ingredients are different, it is theoretically best to use products from the same brand and series. This can prevent adverse reactions caused by conflicts between different whitening ingredients. Many whitening products on the market use vitamin C as the main ingredient. Ellagic acid has extremely high antioxidant properties, which can help the skin inhibit and regulate the production of melanin, and lighten the formed spots.
In addition to choosing whitening products, there is another important point: starting from externally protecting the skin from ultraviolet rays, sun protection care must be taken all year round, and sunscreen must be used whether working indoors or outdoors. When you are outdoors in the hot summer, be sure to bring a parasol and sunglasses with UV protection.
