A lip crease is when someone has a little indent in their bottom lip, creating the appearance of a fuller pout. Angelina Jolie has always had one, and the filler technique came under the spotlight recently because Love Island contestant Gemma Owen appeared to have opted for the look before heading into the famous villa.

We spoke to aesthetic practitioner Carrie Hancox of the Centre for Surgery for her expert opinion on whether Holly Willoughby has had lip filler.

"Holly could have had the ‘keyhole lip technique’ due to the indent in her lower lip," Carrie observed. "This technique creates a subtle divide on the lower and upper lips, giving patients the perfect pout."

Carrie went on to say that Holly, 41, might also have had filler elsewhere in her face. "Holly is absolutely gorgeous and is known for her supple, glowing skin, and recently she's shown off a more 'sculpted' look which could be a result of midface/cheek filler," Carrie says.
