You’ve probably seen the "retinol uglies" on TikTok. Red, peeling, angry skin that looks more like a sunburn than a glow-up. It’s scary. But here’s the thing: retinol is still the undisputed gold standard for basically everything—acne, fine lines, texture, you name it. It works. The problem isn't the ingredient; it's the way people dive into the deep end without checking the water level.
Learning how to start using retinol is less about buying the most expensive bottle and more about playing the long game. It’s a marathon. If you sprint, you’ll trip.
Retinol is a derivative of Vitamin A. When you apply it, your skin eventually converts it into retinoic acid. This process speeds up cell turnover, meaning your skin sheds old, dead cells faster and pushes fresh ones to the surface. It also helps boost collagen. But your skin needs time to build up "retinoid receptors" to handle this new pace. If you go too fast, you're essentially asking your skin to do a month's worth of work in three days. It won't be happy.
Why your skin freaks out (and how to stop it)
Most people quit retinol after two weeks because their face feels like sandpaper. This is called retinization. It’s a real physiological transition period where the skin's barrier is temporarily compromised. Dr. Shari Marchbein, a board-certified dermatologist in New York, often points out that irritation isn't a sign the product is "working" better—it’s just a sign of inflammation.
You don't need to suffer.
The biggest mistake is starting with a high percentage. You see a 1% retinol and think, "I want the strong stuff." Don't do that. Honestly, starting with a 0.25% or even a "granactive" retinoid (which is often gentler) is much smarter. Your skin doesn't care about your ego. It cares about its lipid barrier.
The Sandwich Method is a literal lifesaver
If you have sensitive skin, or even if you don't, use the sandwich method. It’s exactly what it sounds like.
First, apply a thin layer of basic moisturizer. Wait a few minutes. Then, apply a pea-sized amount of retinol. Finally, top it off with another layer of moisturizer. This creates a buffer. It slows down the penetration of the retinol just enough so your skin doesn't go into shock, but the active ingredient still gets where it needs to go.
It’s a game changer. Seriously.
Picking your first product
Walk into any Sephora or CVS and you'll be overwhelmed. There are thousands of options. When you’re figuring out how to start using retinol, focus on the packaging as much as the ingredients.
Retinol is notoriously unstable. It hates air and it hates light. If the retinol comes in a clear glass jar that you dip your fingers into, don't buy it. By the time you’re halfway through the jar, the "active" retinol has likely degraded into useless mush. Look for opaque bottles with pump dispensers. Airless pumps are the gold standard here.
Some solid entry-level options:
- CeraVe Resurfacing Retinol Serum: It’s cheap, widely available, and contains ceramides to help soothe the skin.
- The Ordinary Retinol 0.2% in Squalane: Very simple, very low dose, but the oil base can be a bit heavy for some.
- SkinBetter Science AlphaRet Overnight Cream: This is the "Mercedes" of retinols. It’s expensive and usually sold through doctors, but it’s formulated to be incredibly non-irritating.
- La Roche-Posay Redermic R: A classic French pharmacy pick that most dermatologists trust.
The "Low and Slow" Schedule
Do not use it every night. Just don't.
Start with twice a week. Maybe Monday and Thursday. Do this for two full weeks. If your skin isn't peeling or stinging when you apply your regular moisturizer, bump it up to every other night. Stay there for a month.
Consistency beats intensity every single time.
If you notice "hot spots"—those little dry patches around the corners of your nose or mouth—skip a night. You can even apply a little bit of Vaseline or Aquaphor to those sensitive areas before putting on your retinol to act as a complete block. It’s a pro move that prevents that weird, cracked-skin look.
What about the "Purge"?
Yeah, the purge is real. Because retinol speeds up cell turnover, it brings all the "gunk" currently trapped in your pores to the surface all at once. If you were going to get a pimple three weeks from now, retinol might make it show up tomorrow.
It usually lasts about 2-4 weeks. If you’re still breaking out in brand new places after six weeks, it might not be a purge; it might be a breakout or a reaction to another ingredient in the formula. Know the difference. A purge happens in areas where you normally get acne. A reaction happens everywhere.
The non-negotiables: Sunscreen and Simplicity
If you aren't going to wear sunscreen, do not use retinol. Period.
Retinol makes your skin more photosensitive. You are bringing fresh, "baby" skin cells to the surface, and the sun will fry them. If you skip SPF 30 or higher during the day while using a retinoid at night, you’re actually doing more damage to your skin than if you just stayed on the couch and did nothing. It's a net loss.
Also, strip back your routine.
When you're learning how to start using retinol, put the exfoliating acids away. No glycolic acid, no salicylic acid, no Vitamin C serums at the same time as your retinol. Use a gentle cleanser, a basic moisturizer, and your retinol. That’s it. Once your skin is "retinized" (usually after 3 months), you can slowly reintroduce other actives. But trying to use a 10-step Korean skincare routine with a new retinol is a recipe for a chemical burn.
Real talk on results
You won't see anything for a while. This is the part that sucks.
Most clinical studies on retinol, like those published in the Journal of Cosmetic Dermatology, show that significant changes in fine lines and pigmentation really start to peak at the 12-to-24-week mark.
You might see a "glow" after a few weeks because of the exfoliation, but the deep structural changes take months. If you’re looking in the mirror every morning expecting a transformation, you’re going to get frustrated and quit. Take a "before" photo today. Forget about it. Check back in three months.

Is it for everyone?
Actually, no.
If you are pregnant or breastfeeding, the general medical consensus (and the FDA) says stay away from retinoids. While the amount absorbed into the bloodstream from a cream is tiny, it’s just not worth the risk. Use Bakuchiol instead—it’s a plant-based alternative that mimics some of the effects without the Vitamin A risks.
Also, if you have severe rosacea or eczema, consult a dermatologist first. You might need a prescription-strength version like Altreno, which is formulated specifically to be more hydrating, or you might need to avoid it entirely during a flare-up.
Next Steps for Success
- Audit your current shelf: Put away any "scrubs" or harsh toners for the next month.
- The Patch Test: Apply a tiny amount of your new retinol behind your ear or on your inner forearm for 24 hours to check for an allergic reaction.
- Start the 2-2-2 rule: Use it 2 nights a week for 2 weeks, then re-evaluate.
- Morning Defense: Place your sunscreen right next to your toothbrush so you never forget it.
- Hydrate: Buy a moisturizer with ceramides or hyaluronic acid to support your skin barrier while it adjusts.
Stick with it. The people with the best skin in their 40s and 50s aren't the ones who used the strongest peel once; they’re the ones who used a boring, low-dose retinol consistently for a decade.
