Everyone has seen those blurry, slightly-too-bright photos on Reddit or TikTok. You know the ones. A grainy "before" shot of dark circles and fine lines, followed by an "after" that looks like they’ve been reborn in a vat of collagen. Looking at tretinoin under eyes before and after pictures can honestly be a bit of a mind-game. You start wondering if you’re looking at a genuine skincare miracle or just a very clever ring light.
The truth is somewhere in the middle.
Tretinoin, the gold standard derivative of Vitamin A, is technically only FDA-approved for acne and facial wrinkles, usually excluding the delicate orbital area. But dermatologists have been using it off-label for decades to treat that stubborn crepey skin. It works. It really does. But it also burns, peels, and makes you look like you’ve been through a wind tunnel if you don’t know what you're doing.
The Science Behind the Transformation
Why does it even work? Basically, tretinoin (all-trans retinoic acid) talks to your cells. It tells them to turn over faster. In the thin skin under your eyes, this means you're speeding up the production of collagen and thickening the dermis. Most people think tretinoin thins the skin because of the peeling, but long-term use actually does the opposite. It makes the skin structurally sounder.
According to Dr. Shari Marchbein, a board-certified dermatologist often cited for her expertise in retinoids, the skin around the eyes is about ten times thinner than the rest of the face. This makes it the first place to show age, but also the most prone to "retinization"—that red, itchy, flaky transition period that makes people quit. When you look at tretinoin under eyes before and after pictures where the results are visible, you are usually looking at a timeline of at least six months.
Anyone claiming a two-week transformation is probably selling something or using a filter.
Realism vs. The Filter
Let’s be real for a second. Some of those photos you see online are misleading. If the "after" photo has zero pores and the "before" looks like it was taken in a basement, close the tab. Real results show a softening of "crow's feet" and a slight tightening of that "crepey" texture. It won't fix structural fat loss. If your dark circles are caused by a deep tear trough (a hollow space under the eye), no amount of Vitamin A is going to fill that gap. You’d need filler or a lower blepharoplasty for that.

I’ve seen patients get frustrated because they expect the cream to act like a surgical lift. It won't. What it will do is improve the quality of the skin surface. Think of it like ironing a silk shirt. The shirt is still the same shape, but the wrinkles are gone.
The Sandwich Method and Other Survival Tactics
If you decide to dive into the world of under-eye tretinoin, you have to be tactical. You can't just slap a 0.1% cream on your lower lids and hope for the best. That is a recipe for a chemical burn.
Most experts recommend the "sandwich method." You put down a layer of bland, fragrance-free moisturizer first. Then, a tiny—and I mean tiny, like half a grain of rice—amount of tretinoin. Then another layer of moisturizer. This buffers the entry of the medication into the skin, slowing down the irritation without completely killing the efficacy.
- Start low. If you have 0.025%, start there. Don't go for the high-strength stuff immediately.
- Frequency matters. Once or twice a week is plenty for the first month.
- Buffer. Never put it on damp skin. Water increases absorption, which sounds good but actually just increases the risk of a reaction.
What Most People Get Wrong
The biggest mistake? Putting the product too close to the lash line. Tretinoin migrates. It travels under the skin. If you put it right up against your bottom lashes, it’s going to end up in your eyes. This can lead to a very real and very annoying condition called Meibomian Gland Dysfunction (MGD). Basically, it dries out the oil glands in your eyelids, leading to chronic dry eye.
If you see tretinoin under eyes before and after pictures where the person's eyes look red or glassy, they might be overdoing it. Keep the application to the orbital bone—the hard ridge of bone under your eye. The product will move where it needs to go.
Comparing Concentrations
Not all tretinoin is created equal. You’ve got creams, gels, and microspheres.

The cream is generally better for the eye area because it’s more emollient. Gels are usually alcohol-based and will dry you out faster than a raisin in the sun. Microsphere technology (like Retin-A Micro) is actually pretty cool because it releases the medication slowly over time, which can be much gentler for sensitive areas.
The Timeline of Change
What does the progression actually look like? It’s not a straight line.
Weeks 1-4: The "Ugly Phase." You might see more wrinkles than you started with. This is because the skin is dehydrated and peeling. It’s discouraging. You’ll want to stop. Don't. Just moisturize more.
Months 2-3: The plateau. The peeling stops, but you don't see a huge difference yet. Your skin is just getting used to the "new normal."
Months 4-6: This is where the magic happens in those tretinoin under eyes before and after pictures. The skin looks "glowier." The fine lines you noticed when smiling seem less etched in. This is the result of actual collagen remodeling.
The Sun Factor
This is non-negotiable. If you are using tretinoin under your eyes and not wearing SPF 30 or higher every single day, you are literally wasting your money. You might even be making things worse. Tretinoin makes your skin more photosensitive. The sun breaks down collagen. If you use a collagen-builder at night and let the sun destroy it during the day, you’re just spinning your wheels.

Plus, UV damage is the primary cause of those fine lines anyway. It's like trying to mop a floor while the sink is still overflowing.
Is It For Everyone?
Honestly, no. If you have eczema, rosacea, or extremely sensitive skin, the eye area might be a "no-go" zone for prescription-strength retinoids. Some people find that a high-quality over-the-counter retinaldehyde (like those from Medik8 or Avène) gives them 80% of the results with 0% of the irritation. Retinaldehyde is only one conversion step away from retinoic acid, making it much more potent than standard retinol but gentler than tretinoin.
Also, if you're pregnant or breastfeeding, put the tube away. Doctors generally advise against using any retinoids during this time due to potential risks, even if the systemic absorption from a tiny eye-area application is minimal. It's just not worth the gamble.
Moving Forward With Your Routine
If you’re looking at your own "before" photo and wondering how to get to that "after," start with a plan. Don't rush. Skincare is a marathon, not a sprint, especially when you're dealing with the thinnest skin on your body.
Next Steps for Success:
- Check your current strength: If you have 0.1%, ask your doctor for a 0.025% prescription specifically for the eye area, or mix a tiny dot with your eye cream.
- The 20-minute rule: Wait at least 20 minutes after washing your face before applying tretinoin to ensure the skin is completely dry.
- Occlusives are your friend: On the nights you don't use tretinoin, use a tiny bit of Vaseline or Aquaphor over your eye cream to lock in moisture and repair the barrier.
- Track your progress: Take your own tretinoin under eyes before and after pictures every four weeks in the same lighting. You often won't notice the subtle changes in the mirror, but the photos won't lie.
- Focus on the orbital bone: Stop applying product directly to the lids; stay on the bone and let the product migrate naturally.
Consistency beats intensity every single time. If you can only handle tretinoin once a week, do it once a week. You'll still get there eventually, and you'll do it without the red, flaky mess.
