“Studies suggest you need to use at least 0.25% retinol or 0.025% tretinoin to be effective, so I recommend using a product that specifies the percentage.” When choosing a retinol product, Dr. Rogers says it's best to start with the lowest concentration before moving up. Another thing to consider is your skin type.

Arazlo (tazarotene): “I am OBSESSED with this prescription retinoid. It's the strongest class of retinoids (tazarotene) but so lovely to use with only minimal irritation. After years of trying, this is the first retinoid I've been able to use consistently. And as a dermatologist I've tried a lot.”
