I recently discovered that Sienna Miller swears by this serum, described as a "Botox alternative," for her radiant complexion.

      When it comes to seeking beauty inspiration at the Who What Wear UK beauty desk, Sienna Miller is undoubtedly the celebrity we all turn to. We're eager to learn her beauty secrets, from achieving her effortlessly tousled hair to the fragrance she uses; I want to know everything about her routine. So, when I discovered that Sienna Miller swears by a specific serum that is also favored by dermatologists, skincare specialists, and beauty editors, I was intrigued to find out more.

      It's widely recognized that Sienna Miller is a big fan of Skinceuticals' popular vitamin C serum, C E Ferulic. However, she has recently incorporated a newer product from SkinCeuticals into her skincare regimen. This particular peptide serum is even praised as a "Botox alternative" for its ability to smooth fine lines and give the skin a plump, glass-like appearance. The product in question is SkinCeuticals Ptiox (£135).

      Key ingredients include an advanced peptide complex, PHA, niacinamide, and laminaria extract.

      Pros:

      - Plumps fine lines and wrinkles

      - Enhances skin texture and radiance

      - Users reported improvements in nine types of wrinkles, including crow's feet and laughter lines, after 12 weeks.

      Cons:

      - Quite pricey

      SkinCeuticals describes this peptide serum as a "wrinkle-modulating serum," designed to fill in dynamic expression lines, such as crow's feet and nasolabial folds. It works by diminishing contraction lines, thereby enhancing overall skin texture and radiance, while also targeting areas typically treated with Botox. A clinical trial from SkinCeuticals demonstrated that participants saw a reduction in nine different types of wrinkles over 12 weeks, along with improvements in skin texture and glow. The brand suggests that P-Tiox can also complement injectable treatments like Botox, amplifying their effects.

      It's important to mention that although this serum is costly and definitely a luxury skincare choice, I can personally attest to its effectiveness after finishing my second bottle of P-Tiox. Several skincare experts have also praised it to me, solidifying its reputation. I haven’t had Botox for the past six months, and while I would typically see fine lines reappearing around my eyes, they are now softer and much less noticeable than before treatment. While it may not replace Botox, I appreciate its plumping effects, and if I decide to get Botox again soon, I will certainly use Ptiox to extend the results as long as possible.

      This serum is lightweight and absorbs quickly, making it suitable for all skin types and easy to incorporate into both your morning and evening skincare routines, allowing you to layer it under other products. I’ve been combining it with the C E Ferulic serum, and honestly, my skin has never looked so glassy. Now that it’s endorsed by Sienna Miller, I'm ready to grab a third bottle.
