Retinol has been a longtime fan favorite anti-aging molecule. And for good reason! As a cosmetic ingredient, retinol is one of the few that has decades of research and data behind its efficacy. In fact, this is why in our book, Skincare Decoded, we refer to this active as one the Big Four and stands alongside the champs, ascorbic acid, AHAs, and niacinamide. But, you’ve probably heard of the downside of retinol - flaking, shedding, redness, dryness. While it may sound intimidating, just a couple careful steps can help you reap all the benefits with little to no side effects. So let’s do a review of retinol shall we?
But First! Let’s Review The Retinoid Umbrella
One of the most common questions we get on this topic is - “What is the difference between retinol and retinoid?” Retinoid is actually the umbrella term for the family of ingredients. It doesn't refer to any specific molecule. Here’s a breakdown of some of the most common retinoids you can find on the market:
- Prescription retinoids: This includes compounds like tretinoin (Retin-A), isotretinoin (Accutane), 0.3% adapalene, and tazarotene (Tazorac) which need to be prescribed by your doctor.
- OTC retinoid: There is only one OTC retinoid available right now - 0.1% adapalene. OTC products come with a drug facts label and have a regulated concentration of the active ingredient
- Cosmetic retinoids: retinol, retinal, and retinyl palmitate (<- boooo 👎) are all in this bucket. This isn't regulated - and you can find a wild range of concentrations from a cat's sneeze worth to skin molting levels. This can get a bit wild when you’re product hunting, but you can still find some fantastic anti-aging staples here.
There’s also sort of a 4th category of cosmetic retinoids -- retinol alternatives. Ingredients such as bakuchiol, granactive retinol, and even some plant extracts are positioned as more gentle alternatives. Learn more about these derivatives [here] - which ones are worth trying and which ones trigger our skeptic meter.
What does retinol do for me and how does it work?
In a nutshell, retinol targets keratinocytes, dermal endothelial cells, and fibroblasts - read: skin cells that are in charge of maintaining your skin structure. The stimulated cells produce more collagen, fibronectin, and elastin. All good things!
The results? It’s one of the few ingredients out there with clinically proven skin benefits in almost all fields of skincare. Treating fine lines and wrinkles? Check. Visibly reduce hyperpigmentation? Check! Acne? Check! (check out our other retinoids article for better retinoids for targeted acne treatments). There are even studies on retinol effectively treating notoriously difficult conditions such as crow’s feet and cellulite.
It’s no wonder retinol is still to this day a superstar skincare ingredient. But since retinol is so popular, shopping for retinol can be a pain in the butt. There are so many choices and the quality can vary far and wide in between. Not to mention everyone’s skin needs are different. LET THE CHEMISTS HeLP MMKAY? Let’s bust some retinol myths to help you on your product discovery journey.
Retinol Myth Busting
Retinol Myth #1: Retinol thins out your skin and causes it to burn more easily in the sun.
While it is true that when acclimating to retinol, your skin can become more irritated and prone to sensitivities. But over time, retinol actually thickens your skin. And with or without retinol, it’s always a good idea to use daily sunscreen so you don’t have to worry about inviting photodamage.
Retinol Myth #2: The sun is retinol’s mortal enemy! Do not apply during the day!
Well, you could apply retinol during the day. Retinol as an ingredient is unstable in light. However, if you’re using a well-formulated product, it’ll last long enough throughout the day to work. And no, it doesn’t cause skin cancer. Additionally, there are studies that test retinol and other retinoids as a twice-a-day product. That said, retinol works perfectly fine as a once-a-day active ingredient. So it’s ok leaving it for night use too! It really just depends on your skin’s retinol tolerance.
Okay. We confess that when we first started Chemist Confessions, we were big proponents of pushing for transparent active percentages in products. But HOLY COW the industry has completely bastardized this movement. There are now products that claim 6% retinol complex, whatever that really means. The reality is - retinol concentration is important, and the actual range of proven activity is between 0.1% and 1%. 1% isn’t for everyone, and your skin will let you know. The name of the game here is to start slow and low, so find the right sweet spot for you that won’t overly irritate your skin.
Shopping for Retinol
Convinced? Ready to add retinol to your routine? Here are some chemists’ shopping tips!
*Products that use lingo such as 10% retinol complex don’t necessarily actually have 10% retinol… but this faux transparency isn’t exactly super helpful 👎👎

what do you all think about the Skinbetter Alpharet…retinoid-aha hybrid?!?
Many products dont say how much retinol they have. Are there certain products you recommend that are OTC? Or would you recommend getting prescription retinol?
