While all of these ingredients have something good to offer our skin, which two shouldn't be used together?

While both highly beneficial for the skin, Retinol and Vitamin C spell disaster when used in the same product. Together they amp up skin's sensitivity to the sun, making you vulnerable to burning and UV damage. For the best results, use retinol in the evening and Vitamin C in the morning.
