Kate Middleton's 'Botox in a bottle' isn’t on sale for Prime Day, but it's well worth paying full price for

I rarely shop the Amazon Prime Day sale, and this midlife skincare hero isn't even discounted, but it's the one exception I will always make

It’s rumoured that Biotulin Supreme Skin Gel is a staple in the skincare regime of the Princess of Wales. I put it to the test on my 49-year-old face to see if the hype holds up – and while I’m usually the first to hunt out a bargain and hate spending a fortune on skincare, I would gladly buy this again at full price.

Let me be honest: I never normally spend a lot of money on skincare. Maybe it's something to do with being a 40-something mum – I’m much more likely to shell out for new tyres for my 19-year-old’s car or pop some emergency cash into my 20-year-old university student's bank account than I am to splurge on a fancy cream for my face.

Or maybe it's an age thing. I don't mind spending a little on a brilliant night cream in a bid to make my bedtime routine as relaxing as possible – after all, insomnia and night sweats can make bedtime a lot less appealing than it used to be. But I'm no longer easily impressed by products that promise to reverse the clock. I actually like being 49, and I'm far more interested in making peace with my age than I am in trying to fight it.

The impact of the key ingredient in Biotulin Supreme Skin Gel has been compared to Botox injections, without the need for needles. I've tried the stuff, and I'd buy it again at full price.

That said, I’m surrounded by incredibly talented beauty writers at work (all with beautiful, glowing skin, needless to say) who are forever mentioning products that I feel should probably be on my radar. Factor in that our focus is entirely on catering to the real needs of women over 40, and when I overheard office chat about 'Kate Middleton's botox in a bottle', I decided it was time to start taking notes.

I called in a bottle of Biotulin Supreme Skin Gel to see what the fuss was about.

  • My Initial Thoughts: I'll admit I was highly sceptical. I even joked to my husband that I’d look like HRH within three days.
  • How it works: The gel utilises spilanthol, a local anaesthetic extracted from the Acmella oleracea plant, which works to reduce muscle micro-contractions.
  • The claims: Biotulin claims that the Supreme Skin Gel can provide up to a 25% wrinkle reduction just an hour after application. It can be reapplied throughout the day to soften the look of fine lines around the eyes and on the forehead without leaving that tell-tale 'frozen' look.
  • The Results: While there is zero chance of anyone mistaking me for royalty any time soon, my skin did feel genuinely different after a couple of weeks of consistent use. Brighter. Firmer. Sort of... more perky. I think my before-and-after pictures speak for themselves.

Kate's Botox in a bottle, as we affectionately call it around here, seems to have skipped the discount queue this Prime Day. But it doesn't need a markdown to justify its place in your skincare regime.

According to royal insiders, the Princess of Wales loves this product so much that she even recommended it to former First Lady Michelle Obama.

The Verdict

As someone who rarely shops at Amazon (shh, whisper it...), I usually use Prime Day to look for tech or household upgrades. But if you want a midlife skin pick-me-up that actually delivers without the needles, this is the one exception worth making – deal or no deal.
