Having oily skin can make flawless makeup application a MAJOR challenge, even in the best of weather (that 35-75 degree, zero humidity sweet spot). But when you have oily skin and you鈥檙e facing the summer heat, never mind trying to聽execute and maintain that coveted airbrushed-foundation look. So, I turned to Instagram for some hacks that could help my skin look totally unbothered under the sun and humidity.

Makeup artist and event planner聽Shabnam Khawja seems to have found the solution in a product that we all have in our bathroom stashes: deodorant. Could the same thing that keeps your armpits dry also keep your skin looking matte? Shabnam聽thinks so.

鈥淧utting a stick of deodorant on your face may sound ridiculous, but the powdery ingredients can help mattify the face,鈥 writes Shabnam.聽鈥淎lso, some natural deodorants include mineral salts that can help dry out zits, and bacteria-fighting ingredients that can also curb breakouts.鈥

While the one-two punch combo seems to work聽(Shabnam鈥檚 makeup does look flawless, after聽all), should you really try this Instagram beauty hack at home? Celebrity makeup artist and owner of聽Fancy Face聽Brittany Gray thinks you should leave this one聽on IG.

鈥淢y initial reaction to this specific trend in the makeup world was HELL NO,鈥 says Brittany.聽鈥淎fter doing some research, testing it out myself and trusting my instincts, I鈥檝e come to the conclusion that this hack should be left in the pits instead of on the face.鈥

She聽found that using deodorant as a mattifying face primer did work, but聽if you care about your overall skin health, she thinks you聽should probably聽avoid this beauty trick.聽鈥淔irstly, these products are not formulated with the face in mind! Antiperspirant deodorants often contain ingredients like magnesium and parabens that can clog pores and, over time, even cause acne,鈥 Brittany explains.聽鈥淪ome of these formulas are also photosensitive, which means they can cause damage to the skin when in contact with the sun.鈥澛燳ikes!

Also, Brittany notes, the skin on the face is much more sensitive than the skin on the underarms, and should be treated as such. 鈥淚t鈥檚 similar to how the skin around your eye area should be treated more sensitively than the rest of the face.鈥

So, now that you know deodorant as a face primer is a huge no-no, what should you use to ensure matte makeup application? 鈥淚f you are a believer in treating your skin with the utmost care, I would invest in better quality products that won鈥檛 leave you with dried out, irritated skin or with acne,鈥澛爏ays Brittany.

Brittany聽recommends聽Becca Ever-Matte Poreless Priming Perfector聽($36),聽Laura Mercier Translucent Loose Setting Powder ($38) or聽Urban Decay De-Slick聽Oil-Control Makeup Setting Spray ($38).聽鈥淚f you really want that extra protection, spray Urban Decay De-Slick聽on before your primer and makeup application too,鈥澛爏he recommends.

鈥淣ot every fad is a fad to adopt. Use your judgment and do what feels right to you!鈥 We鈥檙e going to take Brittany鈥檚 advice on this one and keep the deodorant under our arms.
