No. It is not a good idea to mix the sunscreen with another cream, makeup, body lotions, water, coconut oil, etc. This would dilute the sunscreen reducing its SPF and compromising your sun protection. You can, however, apply sunscreen over another skin care product if you've allowed it to absorb into your skin first. Badger sunscreens are very moisturizing and nourishing on their own and you might find that you do not need another moisturizer.
