In the morning, I notice that a yellow/orange residue comes off my skin. Is this normal with the Enzyme-Active Retinol Serum?Updated a year ago

Yes, a small amount of pigment might remain on the surface of your skin after you’ve applied the retinol serum. That said, it might be a sign you’re layering the serum on too thickly - consider using less, or use the excess on your neck, chest, hands, or anywhere else where you’d like a rejuvenating boost.
