How Much Sunscreen Should I Use on My Face?

How Much Sunscreen Should I Use on My Face? — the commonly cited amount for the face is roughly a quarter to a third of a teaspoon, often described as two finger-lengths of product. Using too little is one of the most frequent reasons sunscreens deliver less protection than their labeled SPF.

Key points

• SPF values are tested at 2 milligrams per square centimeter, which for the face equals about a quarter to a third of a teaspoon.
• The two-finger method, applying product along the length of two fingers, is a simple way to approximate an adequate facial dose.
• Applying less than the tested amount can substantially lower the real-world SPF you receive.
• Include often-missed areas such as the ears, hairline, around the eyes, and the neck when measuring your amount.

Frequently asked

Is a pea-sized amount of sunscreen enough for my face?

No, a pea-sized amount is generally too little; most guidance points to about a quarter to a third of a teaspoon for the face alone.

Should I use more sunscreen if I have a larger face or include my neck?

Yes, larger areas and the neck need proportionally more product, so add roughly another quarter teaspoon to cover the neck adequately.
