暴露在阳光下,刺激性化学物质或污染下会损坏我们的皮肤并造成黑斑。这些斑点可能很难治疗。大多数情况下,OTC面霜和乳液可能无法达到预期的效果。柠檬汁因其维生素C含量而成为治疗皮肤斑点的常用疗法。在研究中,发现维生素C可有效治疗色素沉着过度(1)。
在这篇文章中,我们列出了涉及柠檬汁的各种疗法,您可以使用它们来帮助淡化脸上的黑斑。
柠檬汁如何有效去除黑斑?
我们的皮肤会产生黑色素,黑色素是造成其特征颜色的原因。某些因素会导致这种颜料的产生过多,从而导致色素沉着和黑斑。色素沉着的主要原因之一是过度暴露在阳光下(2)。荷尔蒙失调,维生素/矿物质缺乏,胃肠道疾病和压力等其他因素也会导致黑斑。
柠檬汁是一种天然成分,可以单独使用或与其他成分结合使用,以帮助减轻黑斑。果汁具有与其他OTC产品相似的漂白性能。它的天然酸度使其可用作有机漂白剂,可逐渐减少黑/棕点。
柠檬汁中的维生素C通过抑制黑色素生成(也称为黑色素生成)起作用。营养素通常用于治疗皮肤色素沉着和老年斑(3)。
柠檬也可作为收敛剂,抗氧化剂和抗菌剂(4),(5)。在下一节中,我们讨论了使用柠檬帮助治疗黑斑的某些自然家庭疗法。
注意:根据传闻,过量使用柠檬会使皮肤干燥。因此,在肘部使用之前,先对肘部进行补丁测试。如果几个小时后出现瘙痒或皮肤刺激,请勿继续执行这些补救措施。同样,柠檬汁可以使皮肤光敏。因此,出门前要涂防晒霜。

How Often You Should Do This
Apply it daily to your face to lighten the brown or dark spots.
5. Cucumber And Lemon Juice
Cucumber contains antioxidants and silica that help in the gradual lightening of the dark spots (10). The fruit may also rejuvenate your skin.

- Wash it off with water.
How Often You Should Do This
Do this 1-2 times a day.
6. Olive Oil And Lemon Juice
If the dark spots are caused due to prolonged exposure to UV rays, olive oil can help. In a study, the SPF (sun protection factor) of olive oil was found to be the highest among the oils tested (11).
You Will Need
- 1/2 teaspoon of olive oil
- 1/2 teaspoon of lemon juice
What You Have To Do
- Mix the oil with the lemon juice and apply to the dark spots.
- Leave it on for 10-15 minutes and then rinse off with water.

You Will Need
- A few drops of lemon juice
- 3-4 tablespoons of plain yogurt

9. Baking Soda And Lemon Juice
Anecdotal evidence suggests that baking soda can act as a good exfoliator. The grainy texture of baking soda can help exfoliate the top layer of the skin that has the spots. In the process, it could reveal the lighter part of the skin present below it.
You Will Need

您可以尝试以多种方式使用柠檬汁来帮助治疗黑斑。确保您始终在皮肤上使用新鲜柠檬。瓶装果汁可能包含可能损害皮肤的防腐剂。
另外,避免在皮肤上用柠檬汁晒太阳。它可能会使您的皮肤对紫外线过于敏感(14)。
