How much sunscreen should I apply?

Q: How much sunscreen should I apply?

Immediate Answer: 1/4 teaspoon for face (about the size of your fingertip from the tip of your finger to the first knuckle). Most people under-apply, reducing SPF effectiveness significantly. The Science: SPF ratings are tested and calculated based on a standardised application of 2mg of product per square centimetre of skin—this is the official standard from ISO 24444. Most people apply far less, around 0.5–1mg per square centimetre, which is only half of what is needed. Result: the actual protection you receive is much lower than the SPF number suggests. Applying adequate quantity is essential. Finding the Right Dermatologist: Daycream Defence Repair SPF 50 is formulated to absorb well and feel pleasant when applied generously. Use: 1/4 teaspoon for face1/2 teaspoon for neckExtend to chest and hands (sun-exposed areas) Pro Tip: Adequate sunscreen feels moisturised and slightly dewy on skin—not matte or tight. If your sunscreen feels dry or tight, you might be under-applying. Apply more. It should feel like a light moisturiser.
