Think of retinol and retinoids as cousins, not clones; they’re related but different.
The big difference between retinol and retinoidspecifically, prescription retinoidis strength.
“Retinols contain a lower concentration of the active retinoic acid ingredient,” Levin says.
“Prescription retinoids have a much higher concentration of the active ingredient.
“OTCretinol productsare less intense than prescription products and “work more gradually,” she says.
What Is a Retinoid?
Retinoids arevitamin Aderivatives converted into retinoic acid for use in skincare.
They’re also skincare powerhouses that have been used and rigorously studied for decades.
Many retinoids are applied topically, but somesuch asisotretinoin(Accutane)are oral meds.
The retinoids Fabior and Avage (tazarotene) treat psoriasis by calming inflammation and regulating skin cell growth.
What Is Retinol?
Retinol is a punch in of retinoid used mainly in over-the-counter products instead of prescription medications.
“The more conversions, the weaker the product.”
In OTC retinol products, retinol is often combined with other ingredients meant to hydrate and brighten the skin.
Who Should Avoid Retinoids?
“Most skin types can tolerate a retinol or retinoid,” says Levin.
If you have oily skin or have tried retinoids in the past, then prescription-strength retinoids can be tolerated.
If you’re not sure which one is best for you, have a chat with your dermatologist.
And if you’re pregnant or breastfeeding, avoid using retinoids altogether since they might cause birth defects.
How to Use Retinoids and Retinol
The most common side effect of retinoids?
“It’s important to realize you should slowly ease into using a retinoid.”
“If your skin is still tolerating the retinoid, go for every night.”
If Your Skin Is Medium to Deep
Have medium or dark skin?
Start using your chosen retinoid just once a week, Ciraldo suggests.
When to Use Retinoids
Levin recommends that you use retinoids in your nighttime skincare routine.
(Sunlight degrades retinoic acid).
If you have a multi-stepskincare routine, when should retinoids be applied?
According to Ciraldo, it all comes down to the formulation.
“If you are using a retinoid serum, it goes under the moisturizer,” she instructs.
What Products Can’t Be Used With Retinoids?
“Benzoyl peroxide andalpha-hydroxy acidscan deactivate certain retinoids such as tretinoin,” Levin says.
“Be careful with layering products, and check that to discuss your routine with your dermatologist.”
Where they differ comes down to strength, with over-the-counter retinols providing less active ingredient than prescription retinoids.
So deciding which is best for you depends on your skin pop in and skincare goals.
