Best Under-Eye Serums for Puffiness: I Tested 7, Including Plexaderm

Looking for a serum that smooths under-eye puffiness without cracking, flaking, or leaving a white film?

I've tested popular products, including Peter Thomas Roth Instant FirmX, Plexaderm, Instantly Ageless, Insta-TOX, and Dr. Brandt No More Baggage. Some were much easier to use than others, especially on mature skin or under makeup.

These products give short-term visible smoothing, not long-term treatment. If you'd rather try something without a tightening serum, here are a few quick fixes for puffy eyes.

When under-eye serums help — and when they don’t

Not all under-eye puffiness is the same, which is why some “instant” serums work great for one person—and barely helps another.

In my testing, tightening serums work best when puffiness is fluid-related (sleep, salt, allergies, morning swelling, or hormonal shifts). If your bags tend to flare up during hormonal changes, you may be dealing with hormonal puffy eyes, which often need a different approach than topical products alone. 

They’re much less effective on fat pads, malar bags vs festoons because a topical product can’t truly shrink those.

So this page focuses on what I care about most:

Real, visible results — without the usual headaches like flaking, cracking, tightness, or white residue (especially under makeup).

If you're curious how these serums tighten the skin so quickly, I explain that in my guide to instant eye tighteners.

Scroll down to see how these seven serums worked for my mature eyes.

Looking specifically for Plexaderm alternatives? I compare Plexaderm with Peter Thomas Roth, Insta-Tox, Dr. Brandt and other options in my full Plexaderm alternatives guide.

Otherwise, keep reading — below I share which serum worked best for under-eye puffiness (including under makeup).

Why I started testing under eye serums

I’ve had lower eyelid puffiness since my early 20s — and now that I’m older, I deal with the fun combo of puffiness + crepey under-eye texture. And let’s be real… heavy concealer can make that look worse, not better.

So I started testing “instant” tightening serums the way people actually use them: on real mornings, with facial movement, and sometimes under makeup. A lot of them look promising for five minutes… then they crack, flake, or leave a white film.

The before-and-after below is one of the few times I felt like I got the smoothing I was hoping for. These are my real results (not altered). Your results may vary.

Now let’s get into the serums I tested — what worked best, what was ok, and what I wouldn’t buy again.

Which under-eye serums worked best for me

I tested several popular tightening serums myself to see which ones gave me the best visible smoothing, how they wore on mature skin, and which were easiest to use with makeup.

Some worked better than others on my under-eye puffiness, so here’s how each one compared in real life.

1. Peter Thomas Roth Instant FirmX Eye

Verdict: Fast visible de-puffing, but can leave a tight, powdery film if you overdo it.

UPDATE: Peter Thomas Roth has since released its newer Easy-Wear Formula. After using both the original black tube and the updated silver tube, I noticed differences in the consistency, finish, and how it wore under makeup. You can see my full Peter Thomas Roth Instant FIRMx old vs. new formula comparison here.

Best for: Events/quick fixes; light makeup or none.

• Works in minutes; strong tightening.
• Use less than you think; mix with a drop of water if needed.
• If residue appears, you used too much or layered over heavy cream.

2. Plexaderm Rapid Reduction Eye Serum

Verdict: Smoother than the old cream, but still fussy. Works best on bare skin; can feel dry and crack with expression. Sensitive skin may prefer Peter Thomas Roth Easy Eye Wear.

Best for: Quick, photo-ready lift on clean skin.

• Pros: Fast tightening; clearer finish than the old cream.
• Cons: Drying on mature/sensitive skin; makeup layering is tricky; can leave residue.
• Tip: Use a tiny amount; keep your face still 5–10 min to set.

If you want a true comparison of how Plexaderm stacks up against other popular eye-tightening serums, I’ve broken that down separately in my Plexaderm vs competitors guide.

Note: If you experience side effects like a film or residue—see why Plexaderm leaves a white residue and how to prevent it.

3. Preparation H under eyes (should you?)

Short answer: I wouldn't use it on my eye area.

I tested it myself, and it looked greasier and heavier not smoother. Also, Preparation H isn’t made for thin under-eye skin, and it can migrate into your eyes, which can be very irritating.

The main problems are:

• It can look greasy or heavy
• It may pill under makeup
• It can irritate or sting if it gets near the eyes
• It doesn’t address the real causes of puffiness

If you’re looking for a quick fix, you're better of trying one of the instant eye tighteners on this page.

4. Instantly Ageless

Verdict: Works at first, then flakes. Hard to apply smoothly and doesn’t play well with makeup.

Best for: Occasional, short-wear touch-ups on bare skin.

• Reduces puffiness initially; flakes after a few hours.
• Chunky texture; often needs thinning; can look patchy.
• I reach for PTR or EES instead when I need reliability.

5. INSTA-TOX - Serious Skincare

Verdict: Very liquid—shake well. OK for mild puffiness; weaker than PTR for serious bags. Dries powdery.

Best for: Quick, budget-friendly lift on mild puffiness. 

• Can sputter if separated; apply a thin layer and let set.
• Short wear; residue risk—if that’s unavoidable, I’d pick PTR.

6. Dr. Brandt No More Baggage

Verdict: Nice light gel for mild puffiness/brightening; not a heavy lifter.

Best for: Subtle de-puff + brighter look; makeup days.

• Dries clear (no visible residue).
• Finding the right amount takes a try or two.
• Less firming than PTR/EES, but gentler finish.

7. Easy Eye Solutions Instant Eye Tuck (Discontinued)

Easy Eye Solutions Instant Eye Tuck has been discontinued, but I’m keeping this older video because it shows the temporary smoothing effect these types of products can have in real life.

How I apply tightening eye serums to reduce cracking and peeling

I’ve tested several instant tightening serums over the years, including Peter Thomas Roth Instant FIRMx and Plexaderm, and I’ve found that applying them in a very thin layer gives me the smoothest results on mature skin.

If your serum still cracks, flakes, or separates as it dries, this guide explains why instant eye tighteners crack and how to fix it.

Lately, I’ve been using the updated Peter Thomas Roth Instant FIRMx Easy-Wear Formula. Mine came with a small brush, and I’ve found that using the brush helps me spread the product in a thinner, smoother layer than using my fingers.

But just so you know, I found a makeup beauty blender can also work, but I prefer the brush.

How I apply tightening eye serums

1. Apply a hydrating eye cream under the eyes. Let it set in and then blot area if it's too moist or greasy before applying serum.
2. I place a tiny drop of serum on a small brush or beauty blender instead of my finger. This spreads the product in a very thin, even layer, which works much better with tightening formulas. For me, using a brush also seems to help blur those little criss-cross lines under my eyes, instead of letting the serum settle into them.
3. Then I start at the inner corner of the eye — right above the puff.
4. From there, I do one smooth sweep outward toward the temple. The key is placing the serum only on the puffy area, not across the entire under-eye.
5. After applying it (very important), I keep my face completely still for about a minute while the serum dries. That’s why I’m not smiling in this photo. 😉

How much tightening serum to use

Use about the size of a pea, as shown in the photo below.

Finally:

If you’ve battled under-eye puffiness like I have, don’t give up. You don’t need pricey treatments or heavy concealer to look fresher.

Start with a lightweight tightening serum, apply after hydrating, and let it set 5–10 minutes.
