Retinol is one of the top trending skincare topics, but with social media feeds and #SkinToK serving up endless advice, Dr. Geeta Yadav, a Toronto-based board-certified dermatologist and founder of FACET Dermatology, answers the most common questions and addresses misconceptions.
What is retinol?
Retinol is a vitamin-A derivative that is eventually converted into the bioactive form of Vitamin-A, retinoic acid (tretinoin), through a metabolic pathway in the skin, according to Dr. Yadav.
Who is it suitable for?
Dr. Yadav says retinol is suitable for people who want to address photoaging, fine lines, wrinkles, hyperpigmentation, skin roughness and uneven skin texture. The efficacy and tolerability of retinol make it an easier choice for patients who cannot tolerate more potent prescription formats, which mimic the bioactive form more closely. A great option for first-time users is the Elizabeth Arden Retinol + HPR Ceramide Capsules Rapid Skin Renewing Serum, which includes HPR, a next-generation retinoid that is 10 times more potent than pure retinol. The pre-measured capsules ensure a precise, encapsulated dose that is gentle on the skin.
Common misconceptions about retinol
Misconception: Retinol is as irritating as prescription retinoids
Dr. Yadav explains that retinol is typically significantly less irritating because it still must be converted to the active form within the skin, lowering the effective concentration. Tolerability also depends on formulation. Pairing retinol with ceramides and using a stabilized delivery system helps reinforce the skin barrier, which is often the difference between a retinol you can stick with and one you abandon.
Misconception: Over-the-counter retinol is ineffective
According to Dr. Yadav, a well-formulated retinol can deliver benefits comparable to prescription tretinoin with better tolerability, even though retinol itself is about 20 times less potent because it still must be converted in the skin. The bigger issue with OTC retinol is stability—it oxidizes quickly once exposed to air and light, which is part of why some formulas underperform. Single-dose capsule formats solve this by sealing each dose, and there is strong clinical evidence that properly formulated retinol improves fine lines, wrinkles, hyperpigmentation, and photoaging.
