The seemingly subtle differences in ingredients are what make each product vary so much in terms of use. Toner is a universally beneficial product for all skin types. It's best to apply it prior to the moisturizing step of your beauty routine. LA-based esthetician and beauty guru Stacy Cox explains, "Toner primes the skin for moisturizers and serum. It allows for these solutions to penetrate deeper into your skin, helps hydrate the skin and removes any excess dirt or grime that wasn't cleaned off by your facial cleanser" (via Makeup).
The alcohol content in astringents makes the products work best for those who struggle with oily skin, as excess moisture is removed in the application process. If your skin is normal to dry, this can actually be detrimental to your skin's overall moisture level. If you're not sure, Cox notes that toner is the less abrasive choice, saying, "Astringents reduce the acid mantle in your skin as well as the pH balance. You can't 'overdose' on toner, but you can definitely 'overdose' on an astringent."
Next time you're at the beauty counter, don't hesitate to ask questions about which product is best for you. Don't forget to take your makeup off at night, drink water, and get yourself a nice toner or astringent.
