INCI: Rubus Idaeus (Raspberry) SeedRed Raspberry jam is my favorite! However, the seeds can be very problematic because they get stuck in my teeth. Sound familiar? Well, what if you could scrub with the seeds instead of eating them? Raspberry Seeds for your soap and scrubs! When using these in your soap, please grind them up a bit. While the texture is really cool in appearance, whole seeds are a bit too abrasive.
