Serum vs. Emulsion: What's the difference?

 
 
Have you ever been browsing your favorite beauty aisle and wondered: WTF is a serum? or better yet: How is a serum different than an emulsion? If you're alive and a woman you've probably wondered what the answer is at least once. Or maybe you just know that whatever it is, it sounds good and you're willing to try it. Well, you're right sister. Serums are awesome.
 
So, what exactly is a serum?
Answer: A serum is a facial product you apply to your face after cleansing and toning. The active ingredients in a serum are usually highly concentrated and are made up of smaller molecules so they can penetrate the skin more deeply than other products.
 
What type of serum should I use?
Answer: Since the purpose of a serum is to deliver its ingredients directly to the skin, you should choose a serum that targets the problem you are trying to solve (hyper-pigmentation, brightening, wrinkles, acne, dryness, etc).
 
Okay, now what's an emulsion?
Answer: Emulsions are basically lighter versions of moisturizing creams. They're designed to lock in moisture and seal in all the benefits of your essence and serums so there are good reasons to use both. ESPECIALLY if you suffer from dry skin.
