The dry-down. Symptom follows the same architecture at 22–30% oil concentration vs 20-25% (EDP).
More oil, more scent. Longer wear, stronger projection. Symptom sits at the upper end of EDP-grade, overlapping with Extrait.
Read full breakdown
Designer Eau de Toilette typically contains 5–12% fragrance oil. Designer Eau de Parfum contains 15–20%. Extrait sits at 20–30%. Symptom is formulated at 22 to 30 percent oil concentration, the upper end of the EDP range, overlapping with Extrait. Higher oil concentration means longer wear, stronger projection, and a fuller scent profile. Initio Side Effect at 20-25% (EDP) is more dilute than Symptom.

Our Story · Liverpool, UK
You are paying for the bottle.
Designer brands charge £300 or more for a 100ml bottle. The perfume itself costs three to five pounds to make. The rest is theatre: a campaign, a celebrity, a licensing fee, a retail margin, a bottle heavy enough to feel expensive in the hand.
It is simply how the industry has worked for forty years. What has changed is the assumption that you, the buyer, don’t know.
We started The Fragrance World in Liverpool to make one without the designer tax. One bottle. Thirty pounds. No apology, no compromise.

Remarkably close
My partner thought I was wearing the designer original. The scent profile is remarkably close. Already recommended to friends.

On my second bottle
Started with the 5ml sample, now on my second full-size bottle. The oil concentration genuinely makes a difference to how long it lasts.

A 5ml atomiser. Enough for a full week of wear so you can decide on skin, not from a description. Worst case: out £4.95 and a week.

Made in Liverpool, UK. Vegan and cruelty-free. Not affiliated with Initio; referenced here under honest comparative advertising, protected by the UK Trade Marks Act 1994 s.11(2)(b).

Formulated at 22-30% oil concentration, expect 6-10 hours from a single application. That matches or exceeds the longevity of most designer EDPs at 15-20% concentration.
