Foundation/ bb creams for summer??

MAC Face and Body foundation is my pick. It's lightweight, waterproof and lasts a whole day even through hot summer days. It is a dewy, light buildable to medium finish. I have combination skin for reference.

I like the bioderma BB creme's.

ohmynars I always go back to using mineral powder. It doesn't get that oil slick feel to it.

I love BareMinerals Complexion Rescue Tinted Moisturiser. I’ve been through countless tubes of this over the years. I actually prefer this over foundation. It gives me a nice coverage, feels nice on my face, and has SPF 30. Get it at Mecca......

It depends on the humidity level of the day.
If it's low I use a dewy brand (my fav is Garnier BB); if I'm going to be in air-con I wear Nivea Daily Essentials with Maybelline dream primer; and on really hot days with high humity I use Lancome Ultra wear with Bioderma primer.

I find the nude by nature mineral foundation nice and light packed on with mineral natural cover powder

My favourite thing to do is to mix a lightweight moisturiser in with my favourite foundation. Give us a lighter coverage with the same formula that I love

As mentioned earlier, MAC face and body is a great option. It feels really lightweight on the skin. It's perfect for summer.

MAC Studio Face and Body Foundation is meant to hold up well in warmer weather:

MAC Pro Longwear Nourishing Waterproof Foundation is another option. I haven't tried this yet, but I assume that its coverage is heavier than the Face and Body Foundation:

Estée Lauder Double Wear Stay-In-Place Makeup has great staying power. I haven't tried this in sweltering hot weather yet, but it might be worth you getting a sample of it. If you don't like the foundation to look too heavy, apply it with a blending sponge:

You could try a setting spray to keep your foundation lasting longer. I've never tried one because most setting sprays contain alcohol which can dry out the skin, and my skin is already dry.

Mineral foundations either powder or liquid work best in hot weather. Look for matte textures in base and if you want glow add it strategically on top of your base.
