Although vitamin D2 and tomatoes have certain whitening and spot-lightening effects, when they are mixed with cosmetics, they may cause skin irritation or allergic reactions.

Vitamin D2 is a fat-soluble vitamin, which can help the body absorb calcium. However, excessive use may lead to greasy skin, clogged pores and even skin inflammation. Tomatoes are rich in vitamin C and antioxidants, which have a good maintenance effect on the skin, but if they are mixed with cosmetics, the absorption effect may be affected.
