RETINOL ROADMAP

Dermatologist-approved beginner’s guide on how to use retinol

- Aanchal Chaudhary

I: skincare had a superhero ingredient, it would probably be retinol. Loved, feared, and often misunderstood, this Vitamin A derivative is the gold standard in anti-ageing, but also the one that most people get wrong. Whether you've seen it go viral on social media or heard your dermatologist swear by it, the truth is: retinol works when used correctly.

To decode the science, routine, and real results behind it, we spoke to Dr Gagan Raina, Medical & Clinical Director, Cosmetologist & Aesthetic Medicine Specialist at Arisia Skin Clinic, who shared her expert insights on how to introduce retinol safely and make it a long-term ally for your skin.

What is retinol

"Retinol is one of the most misunderstood yet effective molecules in dermatology,” says Dr Raina. "For decades, it has proven itself in clinical studies—not because it is trendy, but because it works.”

Derived from Vitamin A, retinol influences the skin at a cellular level. It binds to retinoid receptors, boosts collagen production, and accelerates cell turnover. In simpler words, it helps your skin behave like it did in your twenties — plumper, smoother, and more radiant. "Retinol stimulates renewal and repair,” adds Dr Raina. “It’s not just an anti-ageing tool; it’s a skin health molecule.”

When to start using it

According to Dr Raina, there's no right age to start using retinol. "The ideal time to start isn’t based on age but on your skin’s readiness,” she explains. "I usually suggest beginning retinol in your mid-20s when collagen production starts to decline.”

Here's how she breaks it down:

Mid-20s: Start low and slow with 0.1% to 0.3% once or twice a week to build tolerance.

30s: Move to 0.5% every other night to address fine lines, uneven tone, and mild sun damage.

40s and beyond: Focus on repair and elasticity with 0.5%-0.75%, used two to three times weekly.
