You've seen the photos. Usually, it’s a grainy "before" shot of someone with visible crow's feet and a "after" shot where they look like they’ve been blurred by a professional editor. It looks fake. Honestly, sometimes it is. But when we talk about Retin A before and after wrinkles, the actual science is way more interesting—and a lot messier—than a filtered Instagram post.
Retin-A isn't a moisturizer. It isn't a "clean beauty" serum you find at a boutique. It is Tretinoin. This is a powerful, vitamin A-derived acid that basically tells your skin cells to stop being lazy. Most people start using it because they're tired of seeing fine lines around their eyes or that one stubborn "11" line between their brows. But here is the thing: the "before" is easy. The "after" takes a level of patience most people simply don't have.
If you’re looking for a quick fix, stop reading. Seriously. Tretinoin works on a cellular timeline, not a weekend-retreat timeline. It takes about 24 weeks—six full months—to see the real structural changes in the dermis.
The Ugly Truth About the Purge and the Peeling
Before the "after" looks good, the "middle" usually looks terrible. You'll hear dermatologists like Dr. Shereene Idriss or Dr. Dray talk about "retinization." That’s just a fancy word for your face falling off. Okay, not literally. But you will peel. You might break out. Your skin will feel tight, like you’ve wearing a mask that’s one size too small.
This is where most people quit. They look in the mirror at week three, see redness and flaking, and decide the Retin A before and after wrinkles promise was a lie. It's not. Your skin is just learning how to turn over cells faster. Normally, your skin cells replace themselves every 28 days or so. Tretinoin kicks that into high gear.

The "before" state is often characterized by a thick layer of dead skin cells (the stratum corneum) and depleted collagen. Tretinoin thins that top layer of dead skin—which gives you that "tret glow"—while simultaneously thickening the deeper layers where wrinkles actually live.
How the Wrinkles Actually Change
It isn't magic. It's biology.
Specifically, Tretinoin stimulates fibroblasts to produce more collagen. It also inhibits the enzymes that break collagen down. So, when you look at a Retin A before and after wrinkles comparison, you aren't just seeing smoother skin; you’re seeing skin that is structurally denser.
- Fine Lines: These are the first to go. Those tiny crinkles from dehydration or light sun damage usually soften significantly by month four.
- Deep Creases: Retin-A won't replace Botox. If you have deep-set structural folds from 40 years of smiling or frowning, a cream won't erase them entirely. It will, however, soften the edges so they look less like "cracks" and more like "character."
- Texture: This is the underrated part of the "after." The sandpaper feel? Gone. The skin reflects light better because it's smoother.
I’ve seen people use the 0.025% strength and expect miracles in a month. It won't happen. Even the 0.1% (the heavy hitter) takes time. In fact, a famous study published in the Archives of Dermatology showed that while 0.1% worked faster, the 0.025% strength achieved nearly identical results after 48 weeks with way less irritation. Lower and slower is usually better for the long game.

Real Talk: The Risks Nobody Mentions
You cannot use Retin-A and "forget" your sunscreen. If you do, your Retin A before and after wrinkles journey will actually end with more wrinkles. Tretinoin makes your skin photosensitive. If you go to the beach without a hat and SPF 50 while on Retin-A, you are basically frying "baby" skin cells that aren't ready for UV exposure.
Also, don't put it near the corners of your nose or your lips unless you want painful cracking. And for the love of everything, keep it away from your eyelids. Some people develop permanent dry eye issues because the medication can migrate into the meibomian glands. That’s a high price to pay for fewer crow's feet.
The "Sandwich Method" and Other Survival Tips
If you want the "after" without the trauma, you have to be smart.
- Wash your face.
- Wait 20 minutes. (Wet skin absorbs the acid too fast, causing irritation).
- Apply a pea-sized amount. Just a pea!
- Buffer it. Put moisturizer on first, then the Retin-A, then more moisturizer.
This is the "Sandwich Method." Purists say it "dilutes" the medication. Honestly? Who cares. If it allows you to use the product consistently instead of quitting because your face is on fire, it's more effective in the long run. Consistency beats intensity every single time in skincare.

What to Expect at Month 1, 3, and 6
Month One: The Disillusionment
You’ll probably look worse. You might have "purged" acne. Your makeup will look cakey because it’s sticking to skin flakes. You'll wonder why you spent the money.
Month Three: The Turning Point
The peeling slows down. You start to notice that your skin feels "bouncy" in the morning. Those fine lines around the eyes start to look blurry rather than sharp. You stop needing as much foundation.
Month Six: The "After"
This is where the real Retin A before and after wrinkles transformation lives. You wake up with a natural sheen. The hyperpigmentation from old sun damage has faded. The fine lines are visibly reduced. You’ve officially reached the maintenance phase.
Actionable Steps for Your Retin-A Journey
If you’re ready to start, don't just go buy the strongest tube you can find.
- Get a Prescription: See a derm or use a tele-health service like Curology or Agency. They can mix the Tretinoin with things like Niacinamide or Tranexamic acid to buffer the blow.
- Strip Your Routine: Stop using Vitamin C, AHA/BHA acids, and harsh scrubs for the first month. Your skin can only handle one "active" at a time while it's adjusting.
- Take Your Own Photos: You see your face every day, so you won't notice the change. Take a photo in harsh, natural light on Day 1. Don't look at it until Day 90.
- Focus on the Barrier: Invest in a "cica" cream or something with ceramides (like La Roche-Posay Cicaplast or CeraVe) to repair your skin barrier on the nights you don't use the Retin-A.
- Start Slow: Twice a week for two weeks. Three times a week for three weeks. Only move to every night if your skin isn't stinging when you apply plain moisturizer.
The transition from the "before" to the "after" is a marathon. It’s boring, it’s occasionally itchy, and it requires a religious commitment to sunscreen. But in a world of over-hyped "miracle" creams, it remains one of the few things that actually changes the architecture of your skin.
Keep your expectations realistic. It won't give you the face you had at sixteen, but it will give you the healthiest version of the face you have now.
