Meghan Markle looked radiant when she attended a gala in Los Angeles last week, and royal fans now know the reason why.

The Duchess of Sussex attended the Paley Honours Gala in Beverly Hills to support her and Prince Harry's close friend, Tyler Perry.

Meghan looked incredible in a black strapless black Oscar de la Renta gown, reportedly worth £4,850.

She also wore a pair of Stuart Weitzman strappy heels (£440) and a striking diamond tennis necklace by Logan Hollowell (£23,327 - £39,605).

Her hair was styled in waves and held up in a chic updo, which showcased her flawless make-up.

The duchess opted for a glowy, fresh look with defined eyebrows and eyelashes. She also appeared to be wearing a body highlighter around her collarbone, shoulders and arms.

And now, thanks to her make-up artist, Daniel Martin, royal fans know exactly what Meghan used so they can replicate her incredible glow.

Mr Martin posted two Instagram pictures: a video of the duchess walking on the red carpet and a picture of her posing for the camera.

He captioned the video: "You glow, girl" Royal fans praised the duchess for her make-up and asked the make-up artist what product he used to achieve the glowy look - which he revealed.

He said: "It’s not an oil but @livetinted Hueglow Liquid Highlighter Drops (Golden Hour)."

The make-up artist revealed he used the products on Meghan's body as well as "strategically" applying it where he would usually place highlighter. The highlighter drops are usually used on the face, but as per Meghan's example they can be used all over the body. They are created by American brand Live Tinted in a soft gold hue and currently retail at £38 on Cult Beauty.

Live Tinted says on its website: "Subtle micro-shimmers meet 73% skincare—squalane, hyaluronic acid, and sunflower seed oil in these innovative, serum-infused glow drops to hydrate, replenish, and moisturize skin while taking your glow to the next level."

Royal fans fell in love with Meghan's glow. One user wrote on Instagram: "Meghan remains unmatched. Absolutely radiant."

Another one said: "I mean!!! She is absolutely stunning and glowing!"

A third one commented: "Stunning. Glowing. Radiant."

A fourth one said: "Effortless slayage as usual."
