How to Start Retinol the Right Way, According to an Aesthetician

Can we skip the dreaded purge?

Now, I've said many times there is no magic skincare product... but if one is close it's retinol. This vitamin A derivative has a pretty impressive résumé from softening the appearance of fine lines to evening skin tone and keeping pores clear. But with all that effectiveness comes the need for guidelines (I'm sure we've all heard the skin flaking horror stories.)

Hitting retinol too hard right from the jump can lead to redness, peeling, unexpected dryness, and a traumatized skin barrier. The good news is with a some patience and a few pointers from actual professionals you can ease in and avoid that phase.

We talked to aestheticians Kara Montoya and Jennifer Hayter about what to know before adding retinol to your routine, how to introduce it without overwhelming your skin, and what results you can realistically expect.

First, What Does Retinol Actually Do?

Retinol is a form of vitamin A that helps support skin cell turnover and collagen production. With consistent use, it can improve the appearance of fine lines, uneven texture, discoloration, and clogged pores. It's one of those ingredients that can work on several skin concerns at once, which helps explain why it's become such a staple in skincare routines.

The catch? More isn't necessarily better. Retinol can irritate the skin, particularly when you introduce it too quickly or use a formula that's too strong for your skin to tolerate. The goal isn't to get through a peeling phase as quickly as possible. It's to find a routine you can actually maintain.

Not All Retinoids Are Created Equal

Before you add the first retinol serum that catches your eye to your cart, it's worth knowing that retinol is part of a larger family of ingredients called retinoids. Retinol, retinal, and tretinoin are related but they aren't interchangeable. They differ in how they're formulated, how they're converted in the skin, and how they may affect your skin.

As aesthetician Jennifer Hayter explains, the formula itself matters just as much as the ingredient. "Not all are the same. They're all a form of vitamin A but how a product is formulated has a lot to do with how well the skin will respond to the product."

So choosing a retinoid isn't simply about finding the strongest option on the shelf. Your skin's sensitivity, current condition, goals, and the supporting ingredients in a formula all matter. Hayter personally likes Skinbetter Science's AlphaRet line, which combines a retinoid with an alpha hydroxy acid and incorporates ingredients intended to support the skin barrier.

How to Start Retinol Without Overdoing It

1. Start slower than you think you need to

If there's one piece of advice to take away from this article, it's this: you do not need to use retinol every night from the beginning. Another aesthetician we chatted with, Kara Montoya, recommends starting with just one night per week and gradually increasing frequency as your skin adjusts. That may feel conservative, especially when product directions or social media routines make nightly use look like the end goal. But your skin needs time to build tolerance, and everyone's timeline will look a little different.

"Start slow. And pay attention to how your skin responds" Montoya advises. If you start to experience persistent dryness, flaking, or irritation, don't push through simply because you think you're supposed to.

2. A pea sized amount really is enough

When it comes to retinol, using more product won't necessarily get you better results. Our aestheticians recommend a small, pea sized amount for the face, applied according to the product's directions.

Retinoids aren't a spot treatment that you can casually dab onto one wrinkle or breakout and expect it to stay there. It's generally intended to be applied in a thin, even layer across the treatment area specified by the product. Retinol is a very small molecule that moves quickly over the entire face with your body heat, this also means you don't want wet skin or hands when you apply it as the moisture fast tracks the delivery allowing the product to sink in too deeply and aggressively.

3. Keep your routine simple

When you're introducing a new active ingredient, this isn't the moment to overhaul your entire skincare routine too. Start with a gentle cleanser, let your skin dry, and apply your retinoid as directed. Follow with a moisturizer that helps keep your skin comfortable and hydrated. If you're particularly prone to irritation, applying moisturizer before your retinoid may help buffer some of its effects. (It's called the sandwich method: layer of moisturizer, layer of retinol, finish with one more layer of moisturizer.)

It's also worth keeping other potentially irritating actives on the sidelines while your skin adjusts. Depending on your routine, that might mean temporarily skipping or alternating exfoliating acids, scrubs, or other strong treatments rather than layering everything together on the same night. The idea is to make it easier to tell how your skin is responding to retinol, instead of leaving yourself guessing which product is causing the problem.

4. Treat sunscreen as part of the routine

You can have the most thoughtfully formulated retinol in your bathroom, but you'll never get the results you're looking for without protecting your skin from the sun. Retinoids can make skin more susceptible to irritation, and sun protection is non negotiable when you're working on concerns like uneven tone and visible signs of aging. You need a broad spectrum sunscreen with SPF 30 or higher every morning, and reapply when outdoors all day. Sunscreen has to be a built in part of the routine, not optional.

5. Know when to take a step back

Some mild dryness or flaking can happen as your skin adjusts, but that doesn't mean you need to tolerate increasingly irritated skin to get results. If your skin becomes very dry, red, feels raw, uncomfortable, or persistently flaky, it's time to pump the brakes. Reduce how often you're applying the product or pause it while your skin recovers. Focus on gentle cleansing, moisturizing, and sun protection before deciding how to proceed.

If you experience significant burning, swelling, or ongoing irritation, stop using the product and seek advice from a dermatologist or other appropriate healthcare professional. Remember, retinol is not a race. Building tolerance gradually is going to make a lot bigger difference long term than repeatedly irritating your skin and having to start over.

So, is Retinol Worth the Hype?

Retinol's appeal is that it can address several common skin concerns, but the changes happen gradually. With consistent, appropriate use, retinol may help:

• Smooth the appearance of fine lines. Retinoids can support collagen and improve the look of early signs of aging over time.

• Improve texture and tone. Skin may look smoother and more even as retinoids help regulate skin cell turnover.

• Reduce clogged pores and breakouts. Certain retinoids are particularly useful for acne because they help prevent pores from becoming blocked.

• Soften the appearance of discoloration. Some retinoid products can help improve the look of uneven pigmentation with continued use.

Alastin Renewal Retinol Serum is a lipid encapsulated retinol serum that supports smoother skin texture, improves skin tone, and reduces the appearance of fine lines and wrinkles. Includes Oat Extract and Silver Mushroom that help calm and soothe skin with anti-irritants and antioxidants.

Hayter's point about formulation is worth keeping in mind here: the right product choice depends on your skin, the concern you're addressing, and how much irritation you can reasonably tolerate. A dermatologist or an aesthetician can help determine which products make most sense for you.

You don't get extra credit for starting with the strongest product available. The best retinoid routine is one that is suited to your skin and sustainable enough to use correctly.
