Many skincare products contain animal products. Beeswax—sometimes listed as its Latin name, Cera alba—is the most common. Lanolin (from wool) is used as a moisturizer, and whey protein is used in anti-aging products. A couple of skincare companies use human cells derived from fetal or baby skin cells! There are plenty of vegan options out there, but if you worry about what’s in your skin cream, read the label, check the company website, or give them a call.
