What is the best moisturizer to use over a retinoid?

The best moisturizer to use over a retinoid is one that is hydrating, gentle, and non-comedogenic. Look for ingredients like hyaluronic acid, ceramides, or glycerin, which help to lock in moisture without irritating the skin. Additionally, a moisturizer containing soothing agents like niacinamide or aloe vera can help alleviate any potential dryness or irritation caused by the retinoid. Always opt for a formula that is compatible with your skin type to maximize benefits.
