In a recent publication, an article explored the overall dermatologic benefits of these agents, including their collaborative roles in skin health. Both niacinamide and retinol have been utilized for the treatment and management of acne, hyperpigmentation, inflammation, sun damage, wrinkles, and other dermatologic issues in many people. In some cases, individuals elect to use only one of these ingredients, while others may combine the two to augment the clinical benefits of each ingredient.
Numerous clinical studies validate the clinical benefits associated with the use of niacinamide and retinol as single-entity products for various dermatologic issues. For example, one study demonstrated that niacinamide is associated with anti-inflammatory properties that may be beneficial in the treatment of acne and rosacea. Another study found that niacinamide may reduce signs of aging and wrinkles. A third study indicated that topical retinols may also be effective against both noninflammatory and inflammatory acne.  

The article also provided recommendations on how consumers could incorporate these two ingredients into their daily skin-care routine and revealed findings that skin-care products that contain both ingredients may be an effective treatment for acne and hyperpigmentation, as well as for diminishing signs of aging and wrinkles. 

Research also indicates that the combination of the two ingredients may also provide additional benefits because niacinamide may protect against the adverse effects associated with the use of retinol, resulting in less skin irritation and dryness. Because retinol may augment photosensitivity, patients should generally apply products containing retinol before bedtime. If an individual chooses to use them during the day, a broad-spectrum sunscreen should be applied afterward. 

Additionally, if a patient is using both of these ingredients together but as individual agents, it is best to apply niacinamide first to provide skin protection before applying retinol. Patients may also choose to use niacinamide for their daytime routine and retinol as part of their nighttime routine. Ideally, these products should be applied to clean, dry skin, and it may take several weeks before noticeable results are observed.
