Best for Sensitive Skin: Ghost Democracy Lightbulb Vitamin C Serum. Zeichner recommends this waterless serum, which he likes for its clean formula and pared-down ingredients list. "Besides the brightening benefits of vitamin C paired with vitamin E, it contains soothing chamomile extract for sensitive skin," he says. It also features bakuchiol, the buzzy, plant-based retinol alternative that helps improve skin tone and texture without any potential side effects of sensitivity.
