Thanks for the feedback, Jessica! Our Skin Serum is made up of many different and nourishing oils. What you’re smelling is the natural scent of those since Frownies avoids adding synthetic fragrances to our products to keep them clean and suitable for those with sensitivities or allergies. The serum also comes in a larger pump bottle if you prefer that over the roller! Feel free to reach out if you have any questions. Take care, Frownies Customer Care
