Learn the correct order for applying Illuminating AOX Serum and sunscreen SPF 50, plus common mistakes to avoid for optimal protection and glow.
Quick Answer
Apply Illuminating AOX Serum first on clean, dry skin, wait 2–3 minutes, then finish with sunscreen SPF 50. This order ensures antioxidants absorb properly and sunscreen forms an even protective film.
Why Order Matters: Serum Before Sunscreen
Antioxidant serums like Illuminating AOX Serum are designed to penetrate the skin and neutralize free radicals. Sunscreens, especially mineral formulas, work by sitting on the surface to reflect UV rays. If you apply sunscreen first, it can block the serum from reaching the skin, reducing its effectiveness.
The main trade-off is waiting time. Layering properly requires a few minutes between products, which can feel inconvenient in a rushed morning. But skipping that pause can cause pilling or uneven sunscreen coverage, so the short wait is worth it.
Step-by-Step Layering Process
- Start with clean, dry skin: Wash your face and gently pat dry. Wait until your skin is completely dry before applying any serum. Applying serum to damp skin dilutes it and reduces absorption.
- Apply Illuminating AOX Serum: Dispense a few drops onto your fingertips and press gently into your face and neck. Use upward strokes and avoid rubbing harshly. Let the serum absorb for 2–3 minutes until it feels tacky but not wet.
- Finish with sunscreen SPF 50: Shake the sunscreen bottle well, then apply a generous amount (about a nickel-sized dollop) evenly over your face and neck. Smooth it on in one direction to avoid disturbing the serum layer. Don't rub vigorously—this can cause pilling and leave gaps in protection.
