The story behind (plated) Skin Science starts in a cardiology lab, not a beauty one. At Mayo Clinic in Rochester, Minnesota, doctors Atta Behfar and Andre Terzic were studying how human platelets help regenerate tissue in heart failure patients, and found that exosomes, the body's cellular healing messengers, were behind significantly better outcomes. Then they pointed that same extract at skin. That is where the plated eye serum comes from.

I like a brand with a straight line back to its science. Plated has its roots in regenerative medicine rather than a cosmetics lab, and the company behind it, Rion Aesthetics, was formed to turn that research into topical products. A quick reality check I find useful: exosomes contain no DNA or living matter, and they are not stem cells. They are messengers, which is a useful way to picture what is in the bottle.

The EYE Serum is the one to start with. It pairs platelet-derived exosomes, through the brand's Renewosome technology, with hyaluronic acid and caffeine from coffee arabica extract, and it is made for puffiness, wrinkles and dark circles. The brand describes a two-speed idea: the hyaluronic acid and caffeine for a quick visible difference, the exosomes working deeper over time. Its sibling, the INTENSE Serum, is a face serum for crepey, thinning skin, so it is not an eye product, and I would treat it as its own step.

The rest of the row gives you cousins to compare. Dermalogica Smart Eye Density is a growth factor serum for hollow under-eyes. Snatch It from point of view. has PDRN and peptides and blurs the area before concealer. Westman Atelier's Eye Activator pairs peptides with exosomes. Tip: apply on clean, dry skin first, and wait five minutes before layering.

Peptides are the quiet workhorses of eye care, short chains of amino acids that formulas use to smooth and firm. This is the shelf I would browse if you want something gentler in feel than the exosome row above, and the formulas here are made for firmness and lift.

The Paula's Choice Pro-Collagen Peptide gel serum has four eye-targeted peptides and comes with a cool metal applicator, so it is a morning one for me. The Ordinary Multi-Peptide Eye Serum is a lightweight dropper bottle aimed at crow's feet, dark circles and puffiness. Dieux Auracle is a peptide and antioxidant serum-gel that hydrates and softens. For a plush, cushiony texture, the Elemis Pro-Collagen Future Restore is the one I would try first.

Dr. Barbara Sturm's Super Anti-Aging Eye Serum is made for the thin, sensitive skin around the eye, and Sulwhasoo's First Care Activating Eye Serum brings ginseng in a red-banded pump. Lancôme's Rénergie H.C.F. Triple Eye Serum is a firming pump bottle for fine lines.

Pairing idea: use a peptide serum in the morning under sunscreen and keep your night routine separate. The buying test is the texture on the back of your hand. Gels should glide, and a serum should sink in within a minute so your concealer does not slide. What I would skip: a heavy, rich texture if you wear makeup every day and hate pilling.

Caffeine has a reputation in eye care for a simple reason: it is made to help the look of morning puffiness. If your eyes swell after a salty dinner, this is the section for you.

The Ordinary Caffeine Solution 5% with EGCG is the straightforward, water-based dropper. Innisfree's Green Tea Caffeine serum comes in a cooling rollerball with niacinamide and five types of hyaluronic acid, which is nice to keep in the fridge. Charlotte Tilbury's Cryo-Recovery Depuffing Eye Serum has a cooling metal tip and an Iceawake and caffeine complex. DAMDAM's Matcha Boost uses Uji matcha with bakuchiol and hyaluronic acid in a silky pump.

For a more botanical take, Susanne Kaufmann's Eye Rescue Serum is an amber roll-on with green coffee and caffeine for puffiness and jasmine extract to brighten. The Dermalogica Awaken Peptide Depuffing Eye Gel adds tetrapeptides, and belif's Aqua Bomb is a cooling gel with caffeine and hyaluronic acid. Youth To The People's Peptides + C Energy Eye Concentrate puts vitamin C in the mix.

The test I trust: apply it, then look in the mirror after ten minutes in daylight. Pat, do not rub. What I would skip: a very fragrant formula if your eyes water easily.

Retinol is the ingredient most people mean when they ask for the strong stuff, and I would treat any of them as a night product and build up slowly.

Drunk Elephant's A-Shaba has 0.1% vegan retinol with 3% caffeine and copper peptides. Dr. Dennis Gross pairs retinol with ferulic acid in a fast-absorbing serum, and Murad's Retinol Youth Renewal comes with a 360 applicator. Summer Fridays' Jet Lag Overnight Eye Serum uses a gentle retinoid blend, which is where I would send a beginner. Perricone MD's triple retinol serum sits in amber glass with CoQ10, and Rodial uses encapsulated retinol in a lightweight gel.

Natura Bissé's Diamond Life Infusion is a night serum with vitamin A in a gold-toned pump. The goop Beauty 3x Retinol Eye Lift Serum combines encapsulated retinol, retinal and Granactive Retinoid with a cooling metal applicator, and it goes on a bit like a gel-cream.

Practical test: start two nights a week, apply a small amount along the orbital bone rather than close to the lash line, and use sunscreen every morning. What I would skip: layering an eye retinol on top of a face retinol on the same night, and anything with an applicator you cannot control.

Dark circles come in different types, and that is why brightening serums often name vitamin C, niacinamide and a few friends. Here are the ones made for the look of shadows under the eyes.

Innisfree's Vitamin C Niacinamide rollerball is made to brighten in seven days, and it is handy in a tote. Kiehl's powerful-strength vitamin C eye serum is made to reduce dark circles while smoothing fine lines. Dermalogica's BioLumin-C is a light antioxidant serum, and Murad's Vitamin C Dark Circle Correcting serum is meant for several kinds of dark circles. Tata Harper's Brightening Eye Gel is a gel-cream that feels fresh.

Clarins Double Serum Eye is a two-in-one concentrate for three types of dark circles. Lancôme's Advanced Génifique Yeux Light-Pearl is oil-free and extends to the lashes, and U Beauty's The RETURN Eye Concentrate has SIREN capsules and diamond powder for a silky finish.

Pairing idea: vitamin C in the morning and a peptide or exosome serum at night. The test is to patch a little on your inner arm first, because vitamin C can sting. What I would skip: a pearly, light-reflecting formula if your concealer already has shimmer in it.

Here is what I would do, in order. Begin with the plated eye serum, one pump a day split between both eyes, on clean dry skin, and give it the five minutes the brand asks for.

Then add one cousin to a different time of day: a caffeine gel in the morning if puffiness bugs you, or a gentle retinol at night once a week. Keep the INTENSE Serum for your face, since it is not made for the eye area.

It is funny that a heart research lab in Minnesota ended up on my bathroom shelf. That is the anchor of this whole edit, and I think it is a good reason to read the label before the hype.
