Hey Sandra,
Thank you for your comment and your attention! 🤍 Generally, we actually define foundation based on the primary solvent, and this can be determined from the first ingredients on the INCI list 🤗
For liquid products, the first ingredient on the ingredient list is almost always water. This doesn’t necessarily tell us about the overall composition of a single product, and almost all silicone-based foundations also contain water 🙏🏻 Apparently, the third ingredient in this product is a silicone-like ingredient (Isododecane) and the fourth most commonly used silicone, which is dimethicone. Based on this, I have assessed that I wouldn’t classify the product as completely water-based. Of course, if the product manufacturer states this, it can absolutely be suitable to be used together with water-based products 🤩
In some cases, it may be beneficial to prefer only water- or silicone-based products in the same makeup routine, but please note that this is by no means a hard and fast rule 😌 It is therefore entirely possible that products made for different bases can be used together, and this often depends on the overall composition of the products as well as the methods and purposes of use.
I hope this clarifies things a bit more, have a lovely day! 💖
