Compatibility of Skin Barrier Cream Base and Ascorbyl Tetraisopalmitate

Based on the product information, the Skin Barrier Cream Base contains Niacinamide (Vitamin B3).

The description for Perfect-C™ (Ascorbyl Tetraisopalmitate) explicitly advises against using it with Vitamin B3 in the same formula.

Therefore, Skin Barrier Cream Base and Perfect-C™ (Ascorbyl Tetraisopalmitate) are not compatible and should not be combined in the same formulation.
