Does the SPF in Your Makeup Actually Protect You? What the Research Says

Does the SPF in Your Makeup Actually Protect You? What the Research Says

Plenty of foundations, tinted moisturisers and powders now carry an SPF rating, which raises a fair question. Is makeup with SPF enough on its own, or do you still need sunscreen? Here is what the research suggests.

How SPF is tested versus how it is used

The SPF on a label is measured in the lab using a generous, even layer of product, specifically 2 milligrams per square centimetre of skin. The problem is that people apply far less in real life. A review found that under normal conditions sunscreen is applied at only about 0.4 to 1.0 milligrams per square centimetre, which reduces the actual protection considerably (Petersen and Wulf, 2014, PMID 24313722). Earlier research reached a similar conclusion, noting that people generally apply too little to achieve the SPF on the label (Bech-Thomsen and Wulf, 1992, PMID 1343224).

Why makeup SPF needs realistic expectations

Makeup is usually applied even more thinly than sunscreen, because the goal is a natural finish rather than full coverage. That means the SPF you actually get from a foundation or powder is likely to be lower than the number on the tube. This does not make SPF in makeup pointless. It simply means it is best treated as a helpful extra layer rather than your only line of defence.

A sensible approach

  • Use a dedicated sunscreen as your base, applied generously, then put makeup over it.
  • Think of SPF makeup as a useful top-up, especially handy for reapplying over the top during the day.
  • Powder SPF can be a convenient way to refresh protection without disturbing your makeup.
  • Do not skip shaded areas like the ears, hairline and neck.

Daily sun protection is worth the effort. A randomised trial found that regular sunscreen use slowed visible skin ageing (Hughes et al., 2013, PMID 23732711). At Verdo we stock the Jane Iredale Powder-Me SPF 30 Dry Sunscreen, handy for top-ups over makeup, along with the Jane Iredale Dream Tint Tinted Moisturiser SPF 15 and Jane Iredale Skintuition SPF 30 Liquid Foundation.

Frequently asked questions

Is makeup with SPF enough sun protection?
It is best treated as a helpful extra rather than your only protection. SPF is tested using a generous layer of 2 milligrams per square centimetre, but people apply far less in real life, around 0.4 to 1.0 milligrams (Petersen and Wulf, 2014). Makeup is usually applied even more thinly, so the protection you get is likely lower than the label number.
Do I still need sunscreen if my foundation has SPF?
Yes. The most reliable approach is to apply a dedicated sunscreen generously as your base, then put makeup over it. SPF makeup is a useful extra layer and a handy way to top up during the day.
Why is the SPF in makeup lower than it says?
SPF ratings assume a thick, even application. Makeup is applied thinly for a natural finish, so you receive less than the labelled SPF. This is the same reason sunscreen often underperforms its label when applied sparingly (Bech-Thomsen and Wulf, 1992).
How can I top up sun protection over makeup?
A powder SPF can be a convenient way to refresh protection without disturbing your makeup. Remember to cover easily missed areas like the ears, hairline and neck.
