What is a Serum and Why Do I Need It?

If you don’t have the first clue what a serum is, you’re not alone. Serums are easy to misunderstand because they're not like any other skin care product, but they're also one of the most essential steps in a well-rounded routine. We’ll show you what serums are and why they’re the best way to get the results you’re looking for.

What is a Serum?

Serums are skin care products that deliver high concentrations of active ingredients to your skin. Serums have formulas tailored to specific skin concerns like acne, hyperpigmentation or wrinkles, and can include potent ingredients like glycolic acid, vitamin C and peptides. Serums also tend to have the lightest consistencies of all your skin care products, ranging from water-like essences to gels and even oils.

How Do I Use Serums?

You should always apply your serums first, for a couple of reasons. First, since your serum has the highest percentage of active ingredients, applying it to freshly cleansed skin gives it the best opportunity to deliver those ingredients where you need them the most. Second, a serum’s light consistency has a hard time getting through thicker products like moisturizers, so if you apply it after your other products, you’re not getting the full benefits of your serum.

How Much Serum Should I Use?

Less is more when it comes to serums. With most formulas, you only need a few drops for your whole face, neck and décolletage, so don’t go overboard! Serums are formulated with the precise amounts of active ingredients your skin can absorb at one time, so using more won’t give you better results and may even lead to irritation if you have sensitive skin.

Is a Serum Right for My Skin Type?

There’s a serum out there for you, no matter what your skin type is! Just make sure you’re up to speed on the best ingredients to use for the skin issues you want to target.

• Vitamin C is great for mature skin (and most other skin types, too) because it stimulates collagen production to firm skin and smooth wrinkles, with the plus of brightening skin tone!
• Dry skin loves ingredients like niacinamide, vitamin E and hyaluronic acid, which helps bind essential moisture to skin for a plumped, dewy finish.
• Oily Skin types should looks for ingredients like exfoliating glycolic acid and lightweight hydrators like hyaluronic acid that balance oil production.
• Even those with sensitive skin can use serums with gentler formulations and skin-soothing ingredients like cucumber, chamomile (often you’ll see this listed as “Bisabolol” in the ingredients) and rosemary extracts.
