Your Ayurvedic Treatment Oil / Moisturizer is designed to bring balance to your skin on a deep level and maintain that balance long term. When you use a different moisturizer than the one designed for your Ayurvedic skin type, the many specific balancing qualities present in the product may cause an imbalance in the long run. For example a pitta skin may get aggravated over time by the warming and stimulating qualities of a kapha product and a vata skin may get aggravated by the cooling property or the slightly sebum-balancing qualities of a pitta product. A wiser course would be to adjust your cleanser or your Daily Repair Serum or perhaps add the Anti-Age Serum to your skin care regime. You could also try applying a thin layer of moisturizing cream on top of your facial oil or start using a facial mask to address temporary skin imbalances.
