I noticed significant improvement with my hyperpigmentation with product. I was purging quite a bit from the retinoids I was using and this helped in fading that post inflammatory hyperpigmentation. The serum feels slightly thicker that the My Signature C serum, however it absorbs pretty well into the skin. My one issue with this though is how difficult it can be to identify if the product is past its use by shelf life due to its color. Difficult to spot oxidation as the serum is red. Overall, its a good performing and affordable Vit C serum with added skin benefiting ingredients. Remember YMMV (your mileage may vary)
