SHE'S made a name for herself as a trusted brand in the skincare industry.
And one of the reasons Trinny Woodall was inspired to start her range was her own battle with severe acne.
In an interview on the Dish podcast, Trinny explained that she had "really bad skin" from the age of 13 to 30.
"I had acne from 13 to 30, which is, I think, why I became so obsessed with skincare, because we do skin care nearly more than make-up, actually, at Trinny London," podcast hosts Nick Grimshaw and Angela Hartnett.
"I remember when people talked to me, they wouldn't talk to my eyes because they were looking and they were studying a rather big spot.
"You know, and they were quite prominent."

As as teenager, Trinny tried to use fake tan to cover up her spots - which was less than successful.
"I thought, hmm, I will do No7 mousse foam tan in a bottle,"
"It was only one colour, whatever your skintone.
"And I'd put it on with a sponge, which I never washed.

"I thought that if I cover my face in a lot of fake tan, you wouldn't see my spots so much.
"You'd stay with people at the weekend, and they would call up my mum and say, can she bring her own sheet?
"She's like the Turin Shroud.
"You know, it all came off, and then the bath always had that stain on it.
"It was disgusting!"
Trinny didn't even put the fake tan until she was about 30, but hasn't worn it since because she has a "really uncomfortable relationship with it and bad memories".
She also revealed how she tried loads of remedies in a bid to clear her skin, before she realised she needed to come up with something herself.
"From like 14, the concept that skincare meant a routine, which could then be a solution, was drilled in my head," she said.
"And then every single year, I would try two, three different brands and do them religiously, do the routine.
"I must have tried about 700, 800 brands in the last 40 years before I then did Trinny London skincare.
"So I was always thinking, what's that in that that might do something?"
Trinny launched back in February 2022, and monthly searches for the beauty brand on the Internet were averaging 99,000 by April this year.
