Figure out your undertones: You need to look at the apples of your cheeks and in between your brows. If you see blue it means you have a cool tone, yellow or golden means a warm tone and green means you have an olive or neutral undertone. “If you put a cool shade of foundation on warm brown skin, guess what it’s going to look like? Ash,” says makeup artist AJ Crimson.

As much as you think your makeup will stay exactly the way it is since you've invested in a really good brand you need to understand that some products like your foundation can oxidise. Some formulas tend to react to the oils in your skin and become warmer or redder. So to prevent your skin from looking weird opt for a shade that's a touch lighter than your skin tone.

“Your foundation or concealer shade could be a great start to matching a lipstick,” says Crimson. Try to work with cream foundations but also make sure that you use a lip liner or a gloss to avoid looking washed out. If you want fuller lips, use a brighter shade of concealer and if you want to define the shape of your lips you should opt for a darker, contouring hue.

“Mist a fluffy brush with facial spray and press it over your makeup—foundation, blush, bronzer, highlighter— to make everything look more like skin.” —Lora Arellano. “Mix foundation with a few drops of a shimmering gel highlighter to create an all-over yet still natural-looking glow.”—Hung Vanngo. “Buy a foundation in two shades: one for imperfections and a lighter shade to highlight your chin, cheekbones and the bridge of your nose.”—AJ Crimson.

"I’m a fan of using blushes on wet skin because they become a bit more opaque and give more of the flushed look that you’re aiming for,” says Sir John, Beyoncé’s makeup guy and a L’Oréal Paris artist. “Try putting on blush while your skin is slightly wet from your foundation, or mist your face with setting spray, and then apply your blush.”

Makeup artist Jillian Dempsey says, "Look for a solid, yellow-based concealer (yellow tones down redness) in a pot, like NARS Soft Matte Complete Concealer, or a palette, like Laura Mercier Secret Camouflage or Revlon ColorStay Concealer." Jillian adds, "Always go a half shade darker than your skin tone—anything lighter will highlight the pimple. Now treat the spot like it’s a tiny surgery: Carefully draw concealer around the edge with a clean brush and a steady hand, blend it toward the centre, and don’t kill the patient. Then dip a cotton swab in finishing powder, and press it gently on top."

When testing shades, “hold them up near your face or even swipe a bit on your jawline,” suggests Sir John. If you have light brown skin like Deepika Padukone's, peachy-beige shades like the NARS Lip Gloss in Giza will work best for you. For cooler skin choose a pinky-nude lip colour. For medium brown skin opt for colours in the caramel to toffee range. Sepia, mocha and chocolate shades, all colours with a hint of red, orange, or golden flecks all look great on dark brown skin.
