Title: Skin Care FAQ: What Is An Emulsion?
Headings: 

Content: For dry skin, the Etude House Moistfull Collagen Emulsion is perfect to adhere moisture and nutrients to skin and leave it feeling hydrated and elastic. The emulsion has small particles of super collagen water and baobab water which absorb quickly into skin; it’s lightweight yet moisturizing, and with a jelly-like consistency and smooth formula, you’ll feel your skin become hydrated and refreshed immediately. For even more moisture, you can also mix a facial oil into your emulsion since emulsions are water based and mixing in an oil means your skin gets both water and an oil-based moisture. Bottom Line
Ever since I started using an emulsion, my skin wakes up feeling hydrated and supple, and I certainly feel it has helped my night cream be more effective. And during the winter months when my skin is fighting against freezing New York City winds, I apply the emulsion in the morning too and that extra layer of moisture really saves the day. At the end of the day, it makes sense why emulsions have been so hard to pin down: because they have different uses and purposes for everyone. Just like treatment products, what emulsion you use and how you use it really depends on your specific needs. But whether you’re trying to find a lighter moisturizer for humid weather, or you’re looking for another layer of moisture to keep your skin from drying out, emulsions can certainly find a way into your routine.
