SPF in things

[BaaCake]

I know that the SPF in foundation isn't to be relied on as you'd need looooads for it to be as effective as the SPF claims but is that the same for moisturiser and CC cream? I've got SPF 50 cc cream and it feels like suncream going on but just wondering how I can tell if I am getting SPF50.

You can’t rely on the spf in any makeup or moisturiser, only sun cream. Unless you’re applying 1-1.5tsp of cc cream to your face, then it’s not going to provide the advertised protection.

Thank you that's super helpful. Most appreciated.

I'll see what 1tsp looks like but expect its way too much. An I meant to put 1 tsp of suncream on my face too? Or less as its suncream?

Oh and if I put half a tsp of factor 50 on does that mean it's factor 25 or does it not work like that?

It doesn’t work like that. You may get the equivalent of SPF 5.

In any case, SPF 25 gives you hardly any more protection than SPF 50. About 3% more.

Wrong way round!

depends what you want/need.

for a 10 min walk from train to office a spf30 moisturiser is adequate.

for lunch outside or activities outside for longer than 10 min you need a proper sun cream.

Ok lovely thanks. Yes I need proper suncream then. Thanks again all x

You could try a proper sun cream that is tinted. It's not going to cover as well but I think it works well especially when you are more concerned about sun protection (like on the beach). I use frezyderm. Have done for years. It feels wonderful and I have never had any problems.

And from there you can have a looksy at those that failed their tests so you can avoid them.

It's important to know that there are two types of radiation that affect skin: Ultraviolet A and B. SPF ratings protect against UVB, and the star rating (used in the UK) protects against UVA. Ideally you should use a sunscreen with high ratings for both SPF and the star rating.

UVA is associated with ageing of the skin and pigmentation as well as skin cancer, particularly squamous cell carcinoma (the second most common type). It can affect human skin even through glass.

UVB causes sunburn, and is linked to particular types of skin cancer - basal cell carcinoma (the most common type) and malignant melanoma.

If you use an SPF product for anti-aging, note that it's actually UVA (the star rating) that causes aging and not UVB (the SPF rating).

And there was a good article in Mail Online in May which someone posted in another thread. It explains about UVA and UVB, the importance of applying enough cream, and the danger of relying on moisturiser or foundation with SPF.
