Hi Ipp! That is a tantalizing comment...are you going to fill us in? I am very curious (off to google that in a second).
I sampled Eau Profonde by Thirdman. Fragrantica says: it is a Citrus Aromatic fragrance for women and men. This atmospheric eau de cologne features ambergris, neroli, bergamot, lime, orange and woodsy notes for depth.
Profonde means "deep, heavy, sound, thorough, inward, profound, inner, acute" according to a translator.
It opens with lime and orange juice, which fades to orange zest. I think the zest part is the neroli and amber? It's very light, and you'd probably have to use more than my small sample to get the full effect. Nice, but not earth-shattering.
