Initio Side Effect is one of the most seductive and compelling releases in the Initio Parfums Privés range — a fragrance built on the house's Psychotropic Compounds philosophy with the explicit intention of creating an addictive, magnetic effect on those around you. It blends vanilla, rum and musks into something that is simultaneously comforting, sophisticated and difficult to ignore. Once you discover what it does on your skin, it has a way of becoming indispensable. The opening is warm and immediately disarming — rum and a spiced citrus accord create a smooth, boozy brightness that feels luxurious from the first spray. The heart develops a creamy vanilla quality that deepens as the fragrance settles, with a subtle coconut thread that adds tropical warmth without tipping into gourmand excess. The base is the real achievement: ambroxan and musks create a skin-close, deeply warm dry-down that is almost narcotically pleasant — this is the note that people lean in to smell, and it carries for an extraordinary length of time. Side Effect earns its name.

Vanilla and rum fragrances interact heavily with skin chemistry — on some skin, Side Effect reads as smooth and sophisticated; on others the sweetness can amplify considerably.
