Khloe Kardashian's dermatologist , Lilia Serobian, shared why you should ditch SPF moisturizer exclusively for E!News.

Sunscreen is the No. 1 product, necessary for everyone, she said. – Of course, moisturizer is important too, but I like to use them separately because SPF moisturizer is less effective.

But what makes an SPF moisturizer less effective?

Of course people can use it, but for a long-term stay outside, there is not enough protection. So, sunscreen should be worn separately to be more effective.

What sunscreens does Lilia recommend now that the weather is getting warmer?

She noted that her customers love EltaMD UV Clear Broad-Spectrum SPF 46, which also comes in color.

People like it and use it because it is not heavy on the skin. It penetrates the skin and has protection for a long time.
