Antioxidants are the unsung heroes of skincare formulations. They defend the skin against oxidative stress caused by free radicals, unstable molecules generated by UV exposure, pollution, and even stress, which accelerate aging and damage skin cells.

For formulators, antioxidants do double duty, they protect the skin and extend the shelf life of your products by reducing rancidity in oils and fats. Whether you’re a brand owner or a DIY skincare maker, understanding which antioxidants to use (and how to use them) can elevate your formulations from good to exceptional.

This guide breaks down five powerhouse natural antioxidants that deserve a spot in your next product.

1. Vitamin E (Tocopherol)

• Why formulators love it: A staple antioxidant that helps prevent oil oxidation in formulations while providing skin-conditioning benefits.
• Best used in: Oil-based products like balms, facial oils, body butters and emulsions.
• Formulation Tip: Use at 0.1–2% in your oil phase, it’s heat-sensitive, so add during the cool-down phase.
