How to Layer FAB Serums and Moisturizers for Best Results

Layering skincare products correctly can make or break your routine. When serums and moisturizers are applied in the wrong order, active ingredients may not penetrate effectively, and you might not see the results you're working toward. First Aid Beauty (FAB) offers a range of targeted serums and rich moisturizers designed to work together—but only if you layer them properly.

In this guide, we'll walk you through the optimal skincare layering order for FAB products, with a focus on serums and moisturizers. Whether you're targeting dehydration, dullness, or signs of aging, following these steps will help you get the most out of your routine.

Why Order Matters in Skincare Layering

The general rule of thumb is to apply products from thinnest to thickest consistency. Serums are typically water-based and lightweight, designed to deliver high concentrations of active ingredients deep into the skin. Moisturizers, on the other hand, are thicker and create a protective barrier that seals in hydration and prevents water loss. If you apply a heavy moisturizer before a serum, the serum's ingredients won't be able to reach the skin effectively.

For FAB products, this means starting with a clean, toned face, then applying your treatment serum, followed by a moisturizer. Some serums, like those containing retinol or acids, may require a wait time before moisturizing to reduce irritation. Always follow the specific instructions on the product label.

• Apply serums immediately after cleansing and toning while skin is slightly damp for better absorption.
• Allow serums with active ingredients (like retinol or AHAs) to absorb for 1–2 minutes before applying moisturizer.
• Use a pea-sized amount of serum and a dime-sized amount of moisturizer to avoid overloading the skin.

Step-by-Step: FAB Serum and Moisturizer Layering Routine

Start with a gentle cleanser to remove impurities. Follow with a hydrating toner like the Hydrating Toner with Squalane + Oats to prep the skin. Then, apply your treatment serum. For example, the Ultra Repair Hydration Boost Serum with Colloidal Oatmeal + Hyaluronic Acid is a great choice for an extra dose of hydration. Pat a few drops onto your face and neck, and allow it to absorb for a minute.

Next, apply your moisturizer. FAB's moisturizers, such as the Ultra Repair Cream, are formulated to lock in moisture without feeling heavy. If you're using a targeted treatment like a retinol serum, you can follow with a moisturizer to buffer any potential irritation. For daytime, finish with a broad-spectrum sunscreen like the Hydrating Sunscreen Milk with Colloidal Oatmeal Broad Spectrum SPF 45.

• For a brightening routine: apply Brightening Micro Powder Exfoliant (as a mask) before serum, then follow with serum and moisturizer.
• If using multiple serums, apply the thinnest first (e.g., hydration serum before oil-based serum).
• Don't forget your eye area: use a dedicated eye cream like Brighten + Glow Eye Cream with Niacinamide after serum and before moisturizer.

Common Mistakes to Avoid When Layering FAB Products

One of the most common mistakes is applying too many products at once. Stick to a simple routine: cleanse, tone, treat (serum), moisturize, and protect (sunscreen in the AM). Avoid mixing incompatible ingredients, such as retinol and AHAs in the same routine unless your skin is well-accustomed. FAB's formulations are generally gentle, but it's still wise to introduce new products one at a time.

Another mistake is not waiting between layers. If you apply moisturizer immediately after serum, you may dilute the serum's potency. Wait at least 30 seconds for lightweight serums and up to 2 minutes for thicker ones. Also, avoid applying moisturizer to damp skin that hasn't absorbed the serum yet—this can cause pilling and reduce efficacy.

• Don't forget your neck and décolletage—they need the same care as your face.
• If you experience irritation, simplify your routine and use a barrier-repair moisturizer.
• Always patch-test new products, especially if you have sensitive skin.

Mastering the art of skincare layering with FAB serums and moisturizers can transform your skin's health and appearance. Start with a clean slate, apply your serum, wait for absorption, and seal everything in with a moisturizer. For a hydration boost, try the Ultra Repair Hydration Boost Serum with Colloidal Oatmeal + Hyaluronic Acid to plump and soothe your skin. Explore more FAB products to build your perfect routine.
