You could also try a hydrating primer to add extra hydration to the skin, while also giving your foundation something to grip onto for a long-wearing finish.
Giorgio Armani Luminous Silk Hydrating Primer and Embryolisse Lait-Crème Concentré Moisturiser are both excellent.
Same goes for sunscreens like Aspect Sun Hydrating Face SPF 50+ 75ml and Ultra Violette Supreme Screen SPF 50+ Hydrating Facial Sunscreen that contain hydrating ingredients.
OK, but what about us oily skin-havers, you ask?
"You might be oily due to the skin being dehydrated, but sorting out your skincare routine will help with that!" Marie says.
"True oily or combination skin types who find foundation separates or looks patchy can apply a mattifying primer like MAKE UP FOR EVER Step 1 Pore Minimizer Primer 30ml over the top of your hydrating products, but only where you get oily like the forehead, nose and chin."
Adore's resident oily skin type Hannah does exactly this to achieve her signature dewy foundation finish that lasts on her oily skin all day!
5. How to Stop Foundation Separating and Pilling.
Find your foundation balls up and flakes off? This usually means your skincare products underneath are clashing.
Always leave enough time for your serums and moisturisers to dry between layers. Applying hydrating serums to damp skin can also help.
If foundation separation is your issue, try to use products with similar textures.
For example, water and oil repel each other, so if your foundation is water-based, using an oil underneath your makeup might cause separation.
Oh, and Marie says adding more powder to fix foundation that's separated or settled in pores only accentuates skin texture more. Her tip?
"Use a small brush to apply powder precisely only to oily areas. Touching up during the day isn't a bad thing - a little touch up keeps foundation looking fresh, whereas packing on powder adds extra texture to the skin."
6. How to Apply Foundation For A Seamless Finish.
Finally, let's talk about how you're applying your foundation.
I've always loved using a flat buffing foundation brush to apply my base, but Marie says it can actually make flaking or dryness look more textured than it is.
"Brushing or rubbing foundation around with a brush can make texture more noticeable. If texture is a concern, try pressing and pushing product into the skin with a damp makeup sponge instead."
