How is SkinCeuticals committed to becoming more sustainable?

SkinCeuticals is committed to looking for ways to improve the sustainability profile of our formulas and ingredient development by aiming to follow these principles:

  • Reduce our water footprint index
  • Source more renewable ingredients
  • Increase biodegradability (of rinse-off formulas)
  • Minimise our packaging through continuous optimisation and innovation and greater use of post-consumer recycled (PCR) materials.

With a synergistic combination of potent antioxidants - Phloretin, pure vitamin C (L-ascorbic acid), and ferulic acid - Phloretin CF is formulated according to the Duke Antioxidant patent. This ensures effective delivery of vitamin C to the skin. In order for our topical vitamin C to be effective it must be formulated with pure l-ascorbic acid (vitamin C) at an acidic pH within the 2.0-3.5 pH range and have a concentration between 10-20%. SkinCeuticals is the only brand to formulate according to these parameters

All SkinCeuticals antioxidant formulations have been tested in final packaging and have been confirmed to remain stable and effective for 36 months, and up to 6 months after opening. L-ascorbic acid (pure vitamin C) is known to change color with time, however oxidation is minimal in SkinCeuticals antioxidant and the formulation is proven to remain effective.


How to Use

  • Apply four to five drops to a dry face, neck, and chest in the morning after cleansing and toning. Complete your regimen with a SkinCeuticals sunscreen.
  • When used together, SkinCeuticals antioxidants and broad-spectrum sunscreens provide the most complete protection against visible aging caused by environmental aggressors.

Rated 4 out of 5 by from I wasn't sure at first... I have used this product for around six weeks. At first I wasn't sure. I was also using another product and didn't see any difference. I stopped using the other product and with time I realised that this is helping my skin. It's summer and I have started to use a tinted moisturiser instead of foundation - and that's down to being a bit more confident with my skin. I was also put off at first with the importance placed on using sunscreen after this product, but it actually helps to remind me to use sunscreen - which really is a must for preventing skin damage. It's not a miracle worker, but my skin definitely feels brighter and clearer. I also prefer this to the CE feurilic.

Rated 5 out of 5 by from Fantastic brightening serum I received this serum just as I had run out of my beloved C E Ferulic. This is as good, if not better! The serum goes on smoothly and sinks in really fast, I enjoy massaging in my serum but there's not alot of time for that. I can really notice my skin looks brighter and smoother. I had a couple of small pigmentation areas that are looking much improved since starting to use the serum 2 weeks ago. I had a couple of spots prior to starting the serum, the marks of which have faded fast & am sure the Phloretin CF has helped. I am prone to breakouts if my skin is not happy, but my skin loves this serum and has not broken out at all. Really happy with this fantastic quality serum.

Rated 4 out of 5 by from Great Vitamin C for oily skin I’ve tried both this and the CE Ferulic over the last 6 months. I like both but find the texture of this is better on my oily skin than that of the CE Ferulic; it seems to absorb that bit more easily. I also don’t get so much of a tingle with this one. My only concern is that I’ve heard that a formula with at least 15% l-ascorbic acid is needed for best protection/prevention so it would be nice to see a mid-way formula made. I haven’t noticed any particular changes in my skin compared to using the CE Ferulic apart from that the redness in my skin is perhaps not quite as prominent.

Rated 5 out of 5 by from Love skinceuticals! I have been using this for a couple of weeks and I was curious as to whether it could beat CE Ferulic in performance, but it is another wonder bottle! Skinceuticals are so consistently reliable and whilst they are pricey it is better than wasting money on cheaper products that do little. It's difficult to describe quite what it does but my acne prone problematic and increasingly aging skin is just better in every way. Every day is now a good skin day!

Rated 5 out of 5 by from Phloretin CF I have been using this Phloretin CF for quite a number of years now - I am now 80 yrs old. I have endless comments about the quality of my skin for my age but I wonder if I am still ok to be using this particular product as it is now quite expensive. However, I have always found it to be comfortable on my skin and wonder if there is anything that is as good as this product that can help my skin age more positively. I do like this Phloretin CF and feel that is the main ingredient for my skin as it contains Retinol. At least I think it does.

Rated 5 out of 5 by from It's a winner! This product proves itself over time. I recently missed a few days of applying it to my skin and used a different serum, and the difference was apparent. In addition to providing great sun protection Phlorentin CF really firms up my skin. My forehead has less expression lines than in comparison to when I do not apply it. It also really enhances my complexion like no other serum has yet; it gives you a great summer glow. I prefer the texture to the other antioxidant serums, as it is not sticky and absorbs straight into the skin. This is really nicely paired up with the HA intensifier as it provides just the right level of hydration for my combination skin. It seems to balance out the oiliness of my t-zones. This is now my must have.

Rated 5 out of 5 by from Best Serum Ever I have been using this daily for a month and I am amazed with the results. I have dark spot marks on my face which were very stubborn. After 2 weeks of using this serum, I could see the dark marks were getting lighter and lighter. Now they are almost gone. This is definitely worth paying the price for. My skin tone looks amazing and my skin feels and looks good.
