    Finally a stable form of vitamin c!

    As someone who suffers from post acne discoloration and melasma, I am a diehard fan of vitamin c serums. I need all things brightening. Finally! A stable form of vitamin c that is not going to oxidize and go bad. A dark bottle in an airless pump is also ideal to keep it most stable. The consistency is more like a lightweight lotion instead of an oil which I also like. It instantly makes my skin so soft, smooth and there is a glow. My skin looks healthy right after applying it. It’s packed with high quality ingredients that make this completely worth it! I can’t wait to see my long term results.

    So Luxe!

    This serum was so easy to incorporate into my skincare routine. It was the perfect texture-not too light or heavy and absorbed quickly, with no weird smell. It left my skin hydrated and glowy with a more youthful appearance. Definitely a must add to your routine!

    Luxurious Serum!

    The texture of this serum is incredibly smooth. My skin felt instantly soothed and hydrated upon application. I loved the radiant glow it gave my skin. The high quality botanical extracts make this serum unique and the glass bottle gives it a luxurious feel. I really enjoyed the slightest smell of plum that came from the serum. I am hoping to see an improvement in my hyperpigmentation with continued use. This serum will be a staple in my skincare routine!

    Game Changer!

    I absolutely adore this C serum! It goes on so nicely and absorbs quickly. My skin looks more hydrated and plump immediately. I also noticed that I have a nice brightness to my skin as well. I am really excited to see it reduce some hyperpigmentation I have on my cheeks.

    I also wanted to note that my makeup when on smoothly over the serum. I use it at night as well and it is a luxurious step in my wind down routine!

    Amazing serum!

    What excites me most about skincare is innovation: formulas that go beyond the usual ingredients and take a more intentional, forward-thinking approach to skin health. Le Prunier Plum Helix C Serum is exactly that kind of product.

    I initially approached it looking for a brightening treatment, but what makes this serum stand out to me is that it offers a more holistic approach to skin quality. It combines radiance with replenishment, barrier support, and a well-aging philosophy that feels much more aligned with where I believe skincare is heading. Rather than relying on the conventional vitamin C playbook alone, it brings together innovative botanical actives and delivery technologies instead of simply repeating the same familiar formulations. The connection to longevity science is especially interesting, given the growing attention surrounding NAD+ and cellular vitality.

    And then there is the sensory experience. The texture is exquisite: luxurious, replenishing, and elegant without feeling heavy or overwhelming. My skin feels softer, more comfortable, and noticeably better nourished after application. One of my favorite aspects is how gentle it feels. Vitamin C has irritated my skin in the past, so I am always cautious when trying a new vitamin C treatment. This formula has been a much more comfortable experience for me. I can enjoy the feeling of a brightening treatment without the irritation I have previously associated with vitamin C products.

    What I appreciate most is…
