The impressive ingredients formulated in PureCeuticals Apple Stem Cell Lightening Serum ($54) did not accomplish for me what it was primarily meant to do, which is lighten and brighten pigmented and acne-scarred skin. This really puzzled me because it contains ingredients that are supposedly highly effective in skin lightening and contains melanin-inhibiting properties. It includes Alpha-arbutin, Azelaic acid and MAP (Magnesium Ascorbyl Phosphate), to name a few.

After five weeks, there was no visible difference in the appearance or intensity of the pigmentation of a few recent tiny acne scars and long-staying melasma on my cheeks.

I even extended the trial period to five instead of four weeks just to give the product more time to work. But still, there had been no remarkable changes in the hyperpigmentation that I was targeting.

I suspect that the Apple Stem Cell Lightening Serum would work better if applied in conjunction with the other PureCeuticals products that are offered in a Hyperpigmentation Kit, which listed it as Step 3 to use after the Pumpkin Enzyme Cleanse (step 1) and Triple Tea Antioxidant Toner (step 2), and prior to the Ferulic C Antioxidant Serum (step 4, but not included in the kit) and Phyto C Polypeptide Creme (step 5) and SPF 30+ Moisturizer (both included in the kit as samples).

I have yet to see if the dark burn scar I just got on my arm lightens with the use of what’s little left of the serum. Overall, I don’t think it’s wise to spend $54 for a 1 fluid ounce product that did not work (in my case) or may not work by itself for you.
