Face Serum 101: Why It Matters What You Wear Underneath

Perfectly Posh collection of face serums, including vegan Nothing Phases Me Anti-Gravity Cholesterol Face Serum, antioxidant Never Grow Up Face Serum with vitamins B and C, Defiant Naked Youth Serum with moringa oil and micronized pearl powder, and Impress Me Intensive Hydration Pressed Serum and Moisturizer

According to a recent study by the Benchmarking Company, a US beauty consumer research firm, 85% of women use a face serum, yet only 22% say they love their serum and think that it delivers as promised, which means there are a whole lot of women out there who have tried a serum only to throw it away for lack of results.

So why use a serum at all?

Unlike a moisturizer which is meant to, well… moisturize, serums are concentrated formulas of ingredients designed to target specific skin issues, like fine lines and wrinkles, redness, dullness, large pores, environmental pollutants, uneven skin tone, etc. Made with smaller molecules than your moisturizer, serums absorb fast and deep for rapid results. The trick is picking the right serum for your skin goals.

At Posh, we’ve tested more face serums than we can count, formulating and reformulating (and re-reformulating) to find the perfect blends of pampering ingredients that actually work, because we know how un-pampering it is to buy a product and watch it gather dust on your bathroom counter. Follow this simple guide to find your ideal face serum:

Which Face Serum Should I Use?

Skin Goal: A brighter complexion

If you’re seeing dullness and uneven skin tone, your skin is telling you it needs more vitamin C and vitamin B in Never Grow Up™ Face Serum. Loaded with 22 botanical extracts and antioxidants, plus caffeine and aloe vera, Never Grow Up brightens for a healthier looking complexion with clean ingredients you can feel good about putting on your naked face.


Skin Goal: Pores? What pores?

Real talk: If your pores are showing, they’re full of dirt, oil, and environmental pollutants. Don’t let it get to you, just get Nothing Phases Me™ Face Serum. It pulls out impurities with activated liquid charcoal, helping pores visibly shrink back to a smaller size while sodium hyaluronate and vegan, crystal-encapsulated cholesterol support collagen and elasticity for youthful, flawless-looking skin.

Skin Goal: Firm skin that doesn’t giveaway your age

You’re only as old as you feel, especially when you incorporate the right anti-aging serum into your skincare routine. That serum is Defiant™ Naked Youth Face Serum. Featuring hyaluronic acid and antioxidant moringa oil with vitamins A and C, it supports collagen and reverses signs of aging while micronized pearl instantly blurs imperfections and illuminates your complexion. Plus, it features a skin-smoothing peptide and algae to tighten and firm.


Skin Goal: Soothed, balanced skin

If you feel like your complexion is always being so extra, help it chill with Impress Me™ Intensive Hydration Pressed Serum, packed with nourishing Poshbiotics™ from black tea kombucha, fermented red wine resveratrol, plus milk and eggs to support your skin’s microbiome and calm sensitive skin. For 2-in-1 benefits, its unique texture transforms into a serum, melting soothing probiotics into skin while doubling as moisturizer.


Face Serum FAQs

Should I use a face serum after my face mask?

Using your normal skincare routine after using a face mask delivers impactful benefits that last, so use your serum after you mask. Not sure which mask to use? Find your match here.

Do I need both a serum and a moisturizer?

That depends on your skin and on your serum. Creamier, more moisturizing formulas can sometimes deliver all the hydration you need, especially in the summer or if you have oily skin. Never Grow Up and Nothing Phases Me are lighter and likely need to be paired with a moisturizer, regardless of skin type.

How often should I use my face serum?

Apply your serum after cleansing your face and using toner, morning and night. If you’re using more than one serum, you can layer lightest to heaviest, or you can apply the lighter one in the morning and the heavier one at night.

How do I apply my serum?

Based on your formula, gently press (no rubbing!) a dime-sized amount, a pump full, or a dropper full into clean, toned skin on your face and neck, targeting goal areas.
