The simple, science-backed routine for more youthful skin

Q: Can I keep my skin looking young and healthy without paying for expensive procedures?

A: After doing a deep dive of the medical literature, my advice is to follow a simple routine:

• In the morning: Use a face cleanser, then apply a moisturizer and a broad-spectrum sunscreen.
• At night: Cleanse your face again, then apply a retinoid and your moisturizer.

The brand doesn’t necessarily matter. Chose what works for your budget and skin type — such as sensitive, dry or oily.
