I have this from lots of products- even ones that are supposed to be hypoallergenic like Clinique. I think they're full of parabens and stuff so you could try more natural ingredients products. I find Avene moisturiser really soothes my skin when it's really sensitive, costs £12 so not too £££.
I have this with lots of products too. Spf seems to make it worse, but not just spf. I use Steam Cream now for day, night and hand cream, it's v natural and doesn't make my skin sting at all. Asos and Tesco stock it, and it's available from their own website.
I agree, probably the SPF ingredients. My son has this with ALL sun creams from Simple/Nivea/Boots Soltan. Strangely, he's ok with Piz Buin which is very fragranced but the SPF bit mustn't be as aggravating to his 12 yr old skin.
Try non SPF, natural products. I like Dr Haushka Rose Moisturiser and you only need a weeny bit.
