Face Serum, The FAQs

You are not alone in having no earthly idea what a serum is. Even if you're the proud owner of several serums, it's not a particularly clear product on it's surface. Think of the contradictions: It's moisturizing, but you still use moisturizer. It can be oily, but it's not necessarily face oil. It can be watery, but is it essence? So many questions and we haven't even gotten to ingredient lists yet!

Skincare should never stress you out (that would sort of defeat the purpose), so we pooled our collective knowledge, did a bit more research, and compiled a cheat sheet of sorts. There's not going to be a test, but study up anyway. We hear skincare talk makes great party ice breakers.

What is serum?
Serum is a skincare product you can apply to your skin after cleansing but before moisturizing with the intent of delivering powerful ingredients directly into the skin. Serum is particularly suited to this task because it is made up of smaller molecules that can penetrate deeply into the skin and deliver a very high concentration of active ingredients. This makes them a great tool for targeting specific skincare concerns, like wrinkles. Goodbye, signs of aging!

Is serum a moisturizer?
Yes and no. Serums can be chock-full of moisturizing ingredients (hyaluronic acid, ceramides) to help skin retain moisture. But, that doesn't make them moisturizers in the traditional sense. Face lotions and creams are richer and create a barrier on top of the skin to keep all that good stuff in.

How often should I use my serum?
Well, this all depends on the serum. Read the label, but once a day will probably cover your bases.

OK but $$$$...
Yes, serums tend to be on the pricier end of the skincare spectrum. But for a pretty decent reason! Remember that bit about being super concentrated and potent? You are getting your bang for your buck here...
Doesn't serum expire really fast?
Certain potent ingredients often found in serum can become unstable once they come in contact with air. Ascorbic acid (vitamin C), for instace, can oxidize and lose efficacy over time. But thanks to science, modified versions of the ingredient (that are water-soluble, etc.) last longer so they can do your skin more good. Best rule of thumb is to store your vial in a cool, dry place (obviously) and use it up within six months to a year.
Is serum right for your skin?
Probably. Get to know your ingredients first. If you're...
Acne-prone: Look for vitamin C (increases collagen production, enhances skin’s repair process, and reduces inflammation), retinol (also an antioxidant, reduces inflammation), zinc (soothes irritation, regulates oil production), and salicylic acid (unclogs pores).
