Cosmetic Skin Solutions Supreme Serum CE

I used to be a devoted user of Cosmetic Skin Solutions CE serum that was a near dupe of Skinceuticals CE Ferulic. They stopped making it awhile ago and launched their Supreme Serum CE that they market as having a super low pH level. I didn’t want to try it because to me, super low means way way below a 3.0 and maybe even below 2.0 pH level. So I tested a sample of it and found the pH level to be pretty good. Here is the reading from my pH meter:

Timeless 20% Vitamin C+E Ferulic Acid Serum Review

I wrote an update awhile ago that said I no longer use Paula’s Choice Vitamin C serum because it made my skin red and blotchy. It took two trips to the dermatologist to realize that is what caused my skin issues so I’ve been using the Timeless 20% Vitamin C+E Ferulic Acid Serum for the past 9-10 months. At the time, I was convinced that moving forward I was going to use Skinceuticals CE Ferulic because it is the gold standard. But, I just couldn’t bring myself to pay that much for a serum.

Paula’s Choice C15 Super Booster Review

Update  – I no longer use Paula’s Choice C15 super booster. I don’t know if they changed their ingredients or if something changed with my skin but it irritates my skin and makes it red/blotchy. I also feel a burning sensation immediately after applying it to my skin. This all began about two months ago and prior to that, I had no problems. So YMMV.


This is a stand-alone review for the Paula’s Choice C15 Super Booster. I also updated my  my post comparing several brands of Vitamin CE serum with photos of what happens when you refrigerate them.

I bought the C15 serum because my favorite Vitamin C serum was discontinued. I have a like/hate relationship with Paul’s Choice** and would prefer to use any other brand…except well, Skinceuticals is just too expensive and their patent doesn’t expire until 2025.

First, I have to admit that Paula’s Choice C15 Super Booster is the reason why Continue reading

Replenix Pure Hydration Hyaluronic Acid Serum Review

I’ve used Replenix Pure Hydration Hyaluronic Acid Serum quite regularly over the past couple of years. It is the hyaluronic acid serum that I keep going back to after trying something else. So I thought I should finally write a review.

Mia’s review: In my last post, I wrote about wanting a low molecular weight (LMW) hyaluronic acid to replace a prescription product from my dermatologist. Well, I’m not sure this is it. It is not marketed Continue reading
