As fall approaches, many people adjust their beauty routines to address dry, irritated skin caused by cooler temperatures. This often involves layering moisturizers and serums. However, an effective skincare regimen requires careful consideration, especially when combining active ingredients. Dermatologist Dr. Mona Foad emphasizes the importance of strategic skincare layering to maintain skin health and protect the skin barrier.

Dr. Foad, founder of MONA Dermatology, advises starting with thinnest to thickest product consistency in a skincare routine: cleanser, toner, water-based treatments like serums, heavier creams, and finally, sunscreen in the morning or facial oil at night. She notes that consistency in routine is as vital as the products themselves.
Proper skincare layering enhances product effectiveness. Active ingredients benefit from direct contact with the skin; applying heavier products first can inhibit absorption. Dr. Foad recommends the following order: cleanser, toner or essence, antioxidant serum (like vitamin C in the morning), treatment actives (such as retinol at night), eye cream, moisturizer, SPF during the day, and face oil at night.
For mature skin, Dr. Foad highlights the need for collagen support and barrier strength, suggesting retinol as a foundation paired with rich moisturizers to counteract dryness. She also recommends using vitamin C serum for antioxidant protection and layering with peptides and hyaluronic acid.
Those with sensitive skin should approach layering cautiously, as some ingredients may exacerbate irritation. Dr. Foad advises consulting a dermatologist and simplifying routines, introducing one product at a time to monitor skin reactions. A basic routine should include a gentle cleanser, fragrance-free toner, a barrier-supporting serum containing niacinamide or ceramides, a simple moisturizer, and mineral sunscreen.
Dr. Foad provides a guide on which ingredients to mix and avoid. For example, retinol works well with peptides, niacinamide, and hyaluronic acid, but should not be mixed directly with vitamin C, AHAs, or BHAs. Vitamin C is most effective with vitamin E and ferulic acid but should not be layered with benzoyl peroxide. Similarly, AHAs pair well with hydrating ingredients but should not be used with retinol or vitamin C on the same night.
For BHAs, particularly salicylic acid, niacinamide is a beneficial partner. Meanwhile, peptides can safely layer with most ingredients, and niacinamide complements a wide range. Azelaic acid pairs well with niacinamide but should be introduced gradually if combined with retinol. Caution is warranted with benzoyl peroxide, as it can deactivate vitamin C and diminish the effects of certain retinoids when applied simultaneously. Dr. Foad advocates for separating these applications and ensuring proper moisturization afterward.
