Expert Analysis · Honest Reviews · Real Results
1.🔬Thirty Days of Retinal

I slathered retinal around my eyes every single night for a month. Not a patch test — the real deal, full commitment, no skipping.

I’ve been testing eye creams for a decade, and most of them are just expensive moisturizers in tiny jars. This one actually has a molecule strong enough to do something.

2.🧪The Science-y Stuff

It’s a retinal (not retinol) eye serum from Beauty of Joseon — the K-beauty brand everyone’s been screenshotting on TikTok. Costs about $18 and promises to soften fine lines in four weeks.

1

0.1% Retinal

The strongest OTC retinoid you can get without a prescription — 11x faster than retinol

2

Encapsulated Delivery

Sits in tiny liposomes so it doesn’t nuke your skin the way straight retinal does

3

No Fragrance, No Dye

Just the active and some soothing stuff — my sensitive eyes didn’t even flinch

3.🌿What’s Actually Inside

Retinal is the hero, but the supporting cast is doing heavy lifting. It’s got a peptide complex and a bunch of hydrating layers that stop the “retinoid uglies” from ruining your week.

  • Retinal: Stimulates collagen and speeds cell turnover
  • Dipotassium Glycyrrhizate: Licorice root extract that calms redness
  • Hydrolyzed Collagen: Plumps skin so lines look shallower
  • Sodium Hyaluronate: Holds 1000x its weight in water

4.Texture & The Weird Part

It’s a milky gel that sinks in about 15 seconds — no greasy film, no white cast. Smells like nothing, which I now realize I should hate but actually love.

Week two was weird: my undereyes looked *dryer* before they looked better. That’s the retinal pushing dead skin up. I almost quit, but by day 20 the flakiness went away and my skin had this unexpected glow. The crepey texture under my eyes? Gone.

💡

One Thing: Apply it on completely dry skin and wait 5 minutes before layering anything else — retinal works best when it’s not fighting other products for absorption

5.📊The Honest Results

My one deep smile line under my left eye is softer — not erased, but definitely shallower. The little feather lines around my outer corners are noticeably faded. My undereye bags? Same as before. This isn’t a miracle worker.
