Why Retinol Still Reigns

It seems that retinol is the “trend” that has surpassed the typical short lifespan of boom-and-bust skincare fads, sticking around for the long haul (and there’s a reason why). Decades after its debut, retinol has remained in the spotlight of dermatology. From how and when to use it, to how it interacts with other active ingredients and whether it’s suitable for sensitive or rosacea-prone skin, retinol continues to spark curiosity and confusion in equal measure. Consider this a clear, dermatologist-backed guide to understanding why retinol is a fan-favourite, and how to use it correctly.

At its core, retinol works by accelerating skin cell turnover and stimulating collagen production. This creates the smooth, textured, even-toned, bright and youthful complexion we all yearn for. Retinol is less about achieving a short-term glow and more about locking in long-term results. It’s a step beyond basic maintenance into proactive, results-driven skincare.

What’s the catch?
Retinol works best when it’s used correctly and mindfully. When misused, it can irritate the skin; when used properly, it can be transformative. That’s why understanding how to use it matters just as much as using it at all.

That being said, let’s rapid-fire the most common questions about retinol, courtesy of our skincare dictionary: Dr. Lisa Kellett.

Your Retinol FAQs, Answered

How often should we use retinol?
Everyday! Retinol is safe and effective for daily use as long as your skin tolerates it. If irritation or sensitivity appears, scale back and consult a professional.

At what age should we start using it?
It depends on your skin goals. Retinol supports collagen remodelling in aging skin and is also effective for comedonal acne, which typically appears in younger skin. There is no golden age for starting, just a golden reason.

How much of the product should we use?
Just one pea-sized amount is enough for the entire face.

Should we expect purging or a breakout?
No! Retinol should not cause a purge or breakout if used correctly.

Can retinol be used on sensitive skin? Rosacea?
Yes, but formulation matters. Sensitive skin and rosacea require the right strength and base, so seeing a dermatologist is essential.

What strength retinol should people use?
Start with 1% retinol in a moisturizing base. We recommend pairing the Clear Clinical 100 Retinol Serum with the Moisturizing Gel for a smooth and hydrated application.

The Ingredient “Cocktail” Questions

Can I use retinol with…

Vitamin C?
Yes, but at a different time.

Niacinamide?
It depends on the formulation, but usually yes.

Hyaluronic acid?
Yes

Exfoliating acids (AHA/BHA)?
It depends on your skin type. Not recommended for sensitive skin.

Benzoyl peroxide?
Yes, but at a different time. Benzoyl peroxide in the morning and retinol at night is the way to go.

And, what skincare ingredients should NOT be used with retinol?
Prescription vitamin A or Accutane.

The Bottom Line

Retinol isn’t here for overnight miracles; it’s about consistency and patience. When used thoughtfully, it can be the best thing your skin has ever had. So, if you’re new to retinol, less is more to begin with. Pair with hydration, go slow and steady, and your soft, firm and glowy skin awaits you. Finally, remember skincare isn’t always one-size-fits-all. Find what works best for you and stick with it.
