Now that spring has sprung and summer is slowly but steadily approaching, I am turning my attention to making my beauty routine more warm-weather friendly. This year, I already have a summer perfume lined up months in advance: Keriros, a new collaboration between Robugier and perfumer Jean-Claude Ellena. [Beauty obsessives will know Elena as the perfumer behind legendary fragrances for Hermès, Bulgari, Van Cleef, and others. Just a whiff of the new fragrance and you could feel his influence.

Kérylos starts with a pleasant grapefruit top note, followed within an hour of application by a sandal, later overshadowed by white musk. I marveled at how refreshing the blend of citrus, mandarin, and grapefruit smelled on my skin (a rarity for me to enjoy citrus perfumes) and how beautiful the deep blue bottle looked on my shelf.

My first impressions underscore how this collaboration stands out from L'Objet's other four scents.

"This is a very personal fragrance for me," Elad Ifrack, founder and creative director of L'Objet, told Marie Claire exclusively. This citrus-musk scent is rooted in his childhood in the Mediterranean, when he skipped school to play in the orange groves with his friends. When the fruit overripened on the trees and fell on hot rocks, the scent would "explode."

To express his childhood in the form of perfume, Ifrach spent a day with Elena in Grasse, France, explaining his sensory memories. From there, Elena created a simple yet powerful blend of yuzu, sedra, mandarin, grapefruit, wild herbs, and musk.

The sedra, in particular, was sentimental to Yifrach, who grew up in Israel. The fruit plays a ceremonial role in Sukkot, the Jewish holiday immediately following Yom Kippur, the Jewish New Year.

"I remember my grandfather always taking an unripe sedra and rubbing it and letting us smell that bitter citrus," Yifrach says. Elena immediately knew what I was talking about."

Robjer also wanted to bring a high aesthetic standard to the fragrance's bottle. The bottle caps, made entirely in the Mediterranean, were created by an organic process of layering two layers of wood lacquer to achieve a cracked marble-like effect. Because no two are alike, "each piece has its own soul," says Ifrach.

Robjer has previously packaged his perfumes in black, but this time Ifrach and Elena opted for ergonomic violet glass made from recycled medicine bottles. The result, the founders claim, is reminiscent of the Mediterranean Sea and also protects the perfume itself from aging.

"Magic really happens when function and design work in beautiful synergy," notes Ifrach. Having tried the fragrance myself, I can't help but agree.
