On its own, CBD has some minor side effects, especially when taken orally. The side effects include dizziness, fatigue, diarrhea, nausea, and vomiting. However, when used with skincare products, such as creams, serums, and salves, CBD has no side effects. This is because when used topically as skincare products, CBD penetrates through the first layers of the skin only. This is how it gets to the endocannabinoid system, unlike when ingested.
That said, CBD skincare products are not associated with any side effects. However, some users may experience side effects due to the additional ingredients used in its manufacture. Some skins may reach to the included ingredients, causing irritation and redness. Due to this, you should always consult your doctor before using new CBD products.
