Ever spent time perfecting your makeup, only to notice your foundation turning patchy, separating around your nose or looking uneven a few hours later? You're not alone! Makeup separation is a common problem, and your foundation isn't always to blame. Sometimes, it's the way you prepare your skin, layer products or apply your makeup. Here are seven common mistakes that could be ruining your base and simple ways to fix them. 1. You're Skipping Proper Skin Prep A smooth makeup base starts with healthy, hydrated skin. Applying foundation over dry patches or excess oil can make it look uneven. The fix: Cleanse your face with a gentle face wash and follow with a moisturiser suited to your skin type. 2. You're Using Too Much Moisturiser Hydration is essential, but applying a thick layer of moisturiser right before makeup can make your foundation slip or separate. The fix: Use a lightweight moisturiser that suits your skin and allow it to absorb before applying makeup. 3. You're Not Letting Skincare Settle Rushing from serum to moisturiser to foundation? Layering products too quickly can cause them to mix, slide around or even pill. The fix: Give each skincare layer a little time to settle before applying the next product. 4. Your Primer and Foundation Don't Layer Well Not every primer works well with every foundation. Sometimes, combining certain formulas or using too much primer can cause your base to separate.
