Foundation – The two 'drugstore' foundations I have in my stash are L’Oreal Lumi Magique and Bourjois Healthy Mix, both of which I love and would recommend for different reasons. I would describe the Lumi Magique as a medium coverage foundation which leaves the skin looking very dewy and radiant, perfect for 'good skin days'. Bourjois Healthy Mix is medium-full coverage, very buildable and leaves the skin looking flawless and is therefore great for days when you want any imperfections completely covered (plus it has no SPF which is great for nights out or any events with flash photography!) Another good drugstore foundation is Rimmel London's Wake Me Up foundation, but have a look around to find the right one for you and your budget (check out my blog post on how to find your perfect foundation!).
Concealer – My favourite affordable concealer is Maybelline Fit Me, which I use on a daily basis under my eyes and on any blemishes. Rimmel's Wake Me Up concealer is also great but I'd describe it as luminous (not quite sparkly but certainly not totally matte) and so can be used under the eyes but I wouldn't recommend for blemishes as you may draw unwanted attention to them by making them too bright and glowy. The other blogger favourite is Collection's Lasting Perfection concealer, which I owned and loved while I was using it but haven't been back to it for ages now...worth having a look at though, especially with the very affordable price tag!
