1) Surprisingly.... Just plain water
Water is the first ingredient in hundreds of beauty products on the market for a few reasons. It helps dilute and stretch recipes allowing for larger batches to be made, it makes products easier to use and it adds moisture. Water is on this list for a few reasons, most of them cautionary. Water in itself isn't a bad thing in products but here's some key takeaways.
First, the moment you add water or a ingredient containing water, your beauty products need a preservative to keep it from spoiling. Now here is where it gets tricky. Water as a main ingredient (in the first five positions on the ingredients label) can actually do the opposite and dry out your skin.
Complicated, right? Instead, focus on your internal consumption. Water is not just essential for your insides, it keeps your skin healthy and healing fast too. Big brands would lose out on millions if they told people " first, drink more water." They're also not going to tell you its cheaper for them to add water to the mix of your body and skin products.
