As above really... My tinted moisturiser has an SPF but want to beef up the protection a bit with a facial sunscreen. Currently using elemis radiance flash balm + a no 7 tinted moisturiser (will be back on the Laura mercier when my birthday comes around...).
I like Anthelios tinted but have to mix it 50/50 with untinted to get a paler shade because I'm ghostly pale and prefer to stay that way (jars from Muji - you can make enough for the entire season in one go - and I use a spatula for hygiene). These days though I use a fluid sunscreen under mineral makeup and that's probably the best routine I've tried yet.
I'd put the sunscreen first after skincare, to protect the skin, as that's where I'd consider skincare to finish. I'd apply primer next to prepare the skin for the base (be it foundation of tinted moisturiser) and to form a surface for it to adhere to (this is where I'd think of the make up part of the routine starting), and then finally I'd apply the tinted moisturiser as the make up/base.
Looks like the Elemis is a moisturiser and primer in one, but I think if you're TM has an SPF then I'm not sure I'd bother adding another sunscreen, but if you do want to, put it over the Elemis, then add your your TM.
Thanks whitetara, I'm not sure what the elemis claims to do tbh, I just liked the results when I got a freebie with a magazine once! I'm a bit slapdash with the tinted moisturiser so want to be sure I'm covering all the key areas.
If you're using sunscreen just make sure it covers the UVA as well as UVB and is a decent spf. I'm using this just now, but plan to switch to this when it's finished. Have you looked at Caroline Hirons' blog? She has quite a lot of info on layering skincare, as has Sali Hughes.
