IT’S AN INVESTMENT IN MY FUTURE SELF . . .

DALILA Salgueiro Trillo, 31, is a freelance marketing expert. She lives in London and spends around £2,000 a year on La Prairie. She says: I HAVE a 52-year-old aunt back in Spain who barely looks in her 30s. She — and I — think her incredibly youthful complexion is down to decades of using La Prairie. I began my own love affair with it aged 25, and I can’t see myself ever looking back.

I’ve always been interested in beauty products; as a child I used to look with fascination through my aunt’s bathroom cabinets, admiring the mysterious glass bottles and vials, and especially the elegant silver La Prairie pots.

I probably have every single product, and stock up in Harvey Nichols department store every three months or so. I particularly like the neck cream (£162) — everyone my age is concerned about ‘tech neck’ — where you develop wrinkles from nodding your head over a laptop for hours on end.

I also love the Caviar Cream, which starts at £329, although it whiffs a bit, so I only use it at night. Yes, it’s expensive, but you don’t slather it on and I think it lasts a long time, and Latino skin has a tendency to pigmentation, which neither I, nor more importantly my aunt, have developed.

As to whether or not it’s better than Botox, well, I’ve tried both so feel qualified to comment.

I had a little Botox in my forehead last year — just to alleviate one little frown line which had appeared between my eyes.

It’s great, but given the choice, I’d go with La Prairie — I think that it’s great preventative skincare. Interviews: ALICE SMELLIE
