when should you start using retinol

Retinol is one of the most powerful ingredients in skincare — but the question most people ask is: when should you actually start using it? The right time depends on your age, your skin type, and your skincare goals.

Is 30 Too Late to Start Using Retinol?

Absolutely not! Starting retinol in your 30s can still give you amazing anti-aging benefits. Most dermatologists say your late 20s or early 30s are ideal, since collagen production starts to decline at that age.

What Is the Rule of 3 for Retinol?

The “Rule of 3” means:

• Apply retinol 3 times a week in the beginning,

• Wait 3 nights between applications,

• Use it for at least 3 months to see visible results.

This slow approach helps your skin adapt and reduces irritation.
