ALTRUIST. Dermatologist Sunscreen SPF 30 – Superior 5-star UVA protection by Dr Andrew Birnie, suitable for sensitive skin – 1 Litre

I use this suncream on the kids every time we go abroad. It's a fantastic suncream. It's lightweight and non greasy, doesn't sting their eyes and is fast absorbing. Neither them nor I have ever been sunburnt whilst using this. It's very value for money and fantastic for those with sensitive skin.

I seldom write product reviews, but I was very pleased with this sun cream, and with the transparent (and altruistic) nature of the company/founders. I am very thankful that Altruist was able to offer this product at a very affordable price, so everyone can access sun protection and apply it at the correct densities every day to achieve the UV protection stated on the bottle (and re-apply throughout the day).The sun cream is a bit shiny, especially with re-application, but I enjoy wearing it at home, and while exercising. It is water-resistant which means it is great while exercising - and because it is very affordable, it can be used appropriately without guilt (e.g. adults need ~ 6 g per leg, ~ 3 g per arm + hand, ~ 6 g on torso, ~ 6 g on back, ~ 1,4 g on face + neck, to reach the SPF on the bottle). It is also great in the winter, especially where I live, when it can get down to -30 Celsius. It is also very friendly for sensitive skin - it is fragrance-free, uses a very gentle preservative system (although I must say using parabens would have been even more effective and gentle - contrary to media, there is no evidence of harm to human health at all, unless you have a confirmed allergy to parabens, as demonstrated by a confirmed patch test conducted by a certified allergist). There can be a slight flash-type cast due to the TiO2 for those with Fitzpatrick types III and beyond, but it is very minimal in my opinion. It does not sting the eyes (since octocrylene is only present at 5%), but could be different for extremely sensitive eyes.I just wanted to share a bit about UVA protection in hopes those not familiar with this find it helpful: UVA is immunosuppressive, causes premature aging, contributes to persistent hyperpigmentation, and exacerbates many skin diseases. The SPF only describes the UVB protection (which is only 5% of the UV dose - the rest is UVA), therefore not every SPF 50 offers the same UVA protection.The UVA 5-star of this cream only says that the sun cream UVA protection is at least 90% of the UVB protection (i.e. 90% of 98%, since it is SPF 50). However, it also has the UVA seal (which states that the UVA protection factor is at least 1/3 of the SPF), meaning this product offers a PPD of at least 17 (which is already quite effective). Although I do not know the exact PPD rating of this sun cream, I am pleased that Altruist decided to divulge the extinction profile of the cream, which shows it remains effective even in the very broad UVA1 range (beyond 380 nm). This is very important because not every broad-spectrum filter covers this area effectively. I appreciate that Altruist SPF 50 contains 8 UV filters: octocrylene (UVB+UVA2), octisalate (UVB), avobenzone (entire UVA1+UVA2), TiO2 (UVB+UVA2+someUVA1), ensulizole (UVB+slightUVA2), Uvinul T 150 (UVB+UVA2), Tinosorb S (UVB+UVA2+UVA1), and Tinosorb A2B (UVB+UVA2+UVA1) for truly comprehensive UV protection. Avobenzone offers most of the protection beyond 380 nm in this sunscreen, but Tinosorb A2B is also effective in this area (because it has a substantial tail after its second peak absorbance at ~ 340 nm) - and the avobenzone is very stable in the formulation because of the Tinosorbs and octocrylene (plus the other filters) so I am very confident in the UVA protection of this sun cream.Overall, a fantastic product. I tried it for the first time earlier this year and was immediately impressed. I now re-ordered 8 bottles.

I was nervous using this. Going through a massive flare up from using a different spf and the sun flared me up so much. I was very sceptical using this. I've patch tested only a little on 1 side. Realistically I don't believe patch testing behind ears and elbows gives accurate reaction if your face skin is problematic. Mine has eczema so no point testing on a non eczema part. I put it on half my face and thought if I react I'll know it's this. Initial thoughts: goes on very smooth. I actually didn't realise I was tinted but it suits my skin tone so I'm grateful. Didn't sting at all, again very impressed. The only thing is I found it slightly streaky putting it on and also can be drying. I've put some pics of me using it immediately, 1 side is red which is my skin today getting better from a massive flare up yday and the other side with the spf(on a collage). The last pic is few hours later, it can be drying. I use vaseline and olive oil as my moisturiser so you can imagine how dry my skin is. So far, 1st few hours, not bad. Hope this is my forever spf 🤞

It’s not orange or tinted as a few have claimed but completely white. Thin enough to spread easily and no smell, perfume or odour. Not greasy like most other high street products. Huge quantity for excellent value.

Good price. Good coverage. Goes on well. Doesn’t smell. Not sticky. Don’t feel the need to get in the shower at the end of the day in the sun to wash the stickiness of suncream off. Handy tubes. No complaints here.
