Why this sunscreen
Fast-absorbing and non-sticky. Exactly what Dr Birnie set out to make: easy to apply, no residue, and the feel of a moisturising cream.

Golfers and cyclists tell us it doesn’t run into their eyes when they sweat, and doesn’t sting.
Keeps at least half of its protection after 2 × 20 minutes in water. Always reapply after swimming or towel-drying.

Good to know
SPF only measures protection against UVB. That’s why you need a broad-spectrum sunscreen: one with both a high SPF (UVB) and a high PPD (UVA).
Causes sunburn, varies with season and location, and increases the risk of skin cancer. Expressed as SPF: SPF 50 filters 98.3% of UVB.
Responsible for skin ageing and deeper skin damage. Present all year round and passes through glass. Expressed as PPD.
How to use
Apply generously to clean, dry skin.
Most people use too little to reach the stated SPF. Dr Birnie’s tip: apply enough that your skin looks completely white before it absorbs.
And always after swimming or towel-drying, even with a water-resistant sunscreen.
Also: avoid direct sunlight between 11:00 and 15:00, wear clothing, a wide-brimmed hat and sunglasses. Babies should not be exposed to the sun.
Ingredients
Altruist uses both physical and chemical filters for optimal protection. They have been thoroughly assessed by the SCCS, the European cosmetics safety committee.
The dermatologist behind it
“Sunscreens should be easy to apply, leave no residue and feel like a moisturising cream. They also need to be affordable, so they can be applied generously.”
Altruist was founded in 2015 by dermatologist Dr Andrew Birnie and Dutch economist David Westerbeek van Eerten. They developed the products in their spare time to keep costs low, and pass that saving on in the price.

More questions? Visit our FAQYes, this sunscreen is suitable for face and body. Looking for a lighter texture for daily use on your face? Then the Face Fluid SPF50 is a good choice.
This sunscreen contains silver chloride, a preservative that has not been tested on children under 2. There is no evidence that it is harmful, but we strictly follow European regulations. The Family Sunspray SPF50 does not contain silver chloride and is suitable from 6 months.
PPD shows how well a sunscreen protects against UVA radiation. In Europe this value must be at least one third of the SPF: around 17 for SPF50. With PPD 52, this sunscreen offers more than three times as much UVA protection.

Under the European standard, a water-resistant sunscreen retains at least half of its protection after 2 × 20 minutes in water. That is why you should always reapply after swimming or towel-drying.
Yes. Apply the sunscreen first and let it absorb fully before applying your make-up. Remember to reapply during the day.
No. The cream absorbs quickly, is non-sticky and feels like a day cream. If you briefly see a white layer while applying, you are using exactly the right amount; it disappears within a few minutes.
SPF30 blocks about 97% of UVB radiation, SPF50 about 98%. Choose SPF50 for fair or sensitive skin, for children, on holiday and during sport. Even more important than the factor is applying enough.
To get the protection stated on the pack, you need 2 mg per cm² of skin. That is roughly one teaspoon per body part and a shot glass for the whole body. In practice, most people apply only half that amount.

Reapply every two hours, and always after swimming, exercising or towel-drying. Even a water-resistant sunscreen loses some of its protection in the water.
Once opened, the product keeps for 12 months, as shown by the symbol on the packaging. Store it in a cool place, out of direct sunlight.
