Of course the most important thing on a sunny day is SPF! For body my favourite is the Hawaiian Tropic Silk Hydration SPF 30, this is the nicest smelling sun cream because it smells of coconuts and makes your skin feel lovely and soft. When in comes to the face i've been putting the Bioderma Photoderm AKN Mat SPF 30, this again has a pleasant citrus scent to it and is great for oily/combination skin because it doesn't feel greasy on the skin and is great for wearing under make-up. Finally don't forget the lips, the trustworthy Carmex Cherry Lip Balm has an SPF 15 and is very moisturising.
If you are an oily skinned girl like myself you need the Kleenex Shine Absorbing Sheets in your life, these little sheets take away any oilyness on the skin without disturbing any make-up you're wearing. A go to product every Summer to refresh the skin is the Caudalie Beauty Elixir, this is perfect for a mid day refresh to the skin without making your face too wet, it also smells lovely too. When it's hot I tend to where as little make-up as possible, a big pair of sunglasses paired with the Topshop Lip Bullet in Joyride has been a go to look for me. There is definitely something special about a red lip and sunglasses.
So those are my sunny day must haves, what products do you reach for on a hot Summer's day?
