Summer is a slog for any makeup routine: In the humidity and unrelenting sun, makeup tends to just slide right off skin. So, of course, it's the time of year that you have more occasions to get a little dolled up and spend a day outdoors (weddings, picnics, and rooftop celebrations abound). What's a natural-makeup lover to do? Well, your options aren't robust, but they're also not bad.

To start, some information regarding waterproof ingredients and comedogenicity. The ingredients used to create waterproof products are typically not of the natural or nontoxic variety—and they also cling to skin, making them very often pore-clogging.

Comedogenicity and noncomedogenicity (read: whether it will or will not clog your pores) is a sliding scale with a lot of nuance. As board-certified dermatologist Mona Gohara, M.D., tells us, "Even if two people are predisposed to acne, what is noncomedogenic to one person might be so for another." Also, says cosmetic chemist Ron Robinson, "Just because a product has a full list of ingredients that are not comedogenic, the end result can still clog your pores." And, finally, says holistic esthetician Kimberly Yap Tan: "If a product has an ingredient that does tend to be pore-clogging, maybe its formulated with such a low dose that it won't bother your skin." (You can read our full breakdown on comedogenicity in beauty products here.)

With natural and nontoxic products, they'll use water-repelling oils and waxes to get the job done. These, too, tend to be better for pores. They will not be as durable as the non-natural waterproof variety, and they will not be as pore healthy as, say, an all-natural tinted moisturizer. But, if you need something that will hold up against a pool party that you can still feel good about, these will be your best bet.
