Kate Middleton's secret to her flawless complexion is said to be the Biotulin Supreme Skin Gel – a 'no-needle Botox' serum that's now on sale. The Princess of Wales reportedly uses this German-made face serum, which contains Botox-like ingredients but without the needles, and it's currently available on Amazon for £39.

The royal's makeup artist, Carl Ray, revealed that the Biotulin Supreme Skin Gel is one of Kate's go-to anti-ageing skincare products. Dubbed as a 'natural alternative to Botox', the serum claims to provide wrinkle-busting results that last up to nine hours, promising smooth and supple skin.

One satisfied customer shared that the product 'takes years off you as it tightens and wrinkles disappear'. Another user expressed their love for the 'tightening feel the product has on the face upon applying.'

This anti-ageing skincare product works by reducing muscle contractions and relaxing the face with spilanthol, a plant-derived ingredient known to reduce fine lines caused by facial movements. It also contains hyaluronic acid to plump up the skin and keep it hydrated.

Biotulin assures that the Supreme Skin Gel can deliver up to 25% wrinkle reduction just an hour after application, without affecting your facial expressions or causing your skin to feel numb. The brand emphasises that 'unlike needle injections, your features will still be reanimated and beautiful'.

The Biotulin Supreme Skin Gel is currently on sale at Amazon

It can be slotted into your beauty routine at any time before you apply your usual moisturiser. Shoppers are absolutely loving this skincare gem, with Amazon reviews filled with glowing reviews. The product has racked up over 1,000 five-star ratings.

One thrilled user said: "I wished I had found this sooner. It is a very nice product and feels good on the skin. This is a serum and not sticky like cream. Once applied you don't realise you've put it on. 10/10."

Another exclaimed: "This really is amazing! It does exactly the same job as Botox in a skin gel. I cannot believe how good this is. I love it. The best product I have ever used. I would highly recommend this. I will never stop using it! A real breakthrough. Wow!"

A third added: "I am 65yrs young. The only place I have deep wrinkles is around my mouth/nose area. Since using Biotulin I have noticed that they are not so prominent."

Despite the rave reviews about its miraculous results, some users weren't too happy with the packaging. One reviewer suggested: "I would also like to suggest a bottle that shows the level of content; as a new customer, this was a considered purchase and to know how much I have used would help me budget for the next bottle."

The Bare Minerals Skinlongevity Long Life Serum, retailing at £58 in Boots, comes in a transparent glass bottle so you can see exactly how much product is left, minimising waste.

It's also rumoured that the Princess of Wales uses Rodial's Bee Venom and Placenta 24 Carat Gold Ultimate Creme to fight signs of ageing. Normally setting you back a whopping £750, it's currently back in stock and on sale for just £95 – a huge saving of £655.
