I don't know how accurate this statement can be. There are products out there that have retinol in there for day use. Dr. Brandt, Peter Thomas Roth, and PCA Skin all have products for day use with retinol in it. PCA even mixes C & retinol in their A&C Synergy serum. (very nice, hate the pump and pricey) When I used to break out more, I used to mix my Philosophy vitamin c powder with my retinol cream or my Philosphy Help Me and had good results.

While they both contain ferulic, they are fundamentally different products. In the Skinceuticals, the ferulic stabilizes the Vitamin C (the main ingredient). In this product, the ferulic complements the Retinol (the main ingredient). Ferulic is just a pretty good antioxidant, but Vitamin C and Retinol are really the power players in each product. Vitamin C is the gold standard in collagen building and antioxidant protection (preventing/undoing cellular damage). Retinol is the gold standard in cellular turnover (making new, plump, radiant cells to replace the old, dull ones). While they function differently, they both result in more luminous skin and a reduction in wrinkles. Retinol will also prevent acne, whereas Vitamin C is better at correcting dark spots. Typically, you don't find Retinol and Vitamin C (as ascorbic acid) in products together, since they inactivate one another.
In a perfect world (where money grows on trees), you'd want to use the Skinceuticals in the morning and a retinol product in the evening. You should always use retinol (like this product) at night since it is inactivated by sunlight. Also, you SHOULD NOT use a retinol and a Vitamin C product containing ascrobic acid (like Skinceuticals) one right after the other since they will inactive one another (a huge waste of money).
If you decide to use a retinol serum, there are cheaper, more effective products out there than this one. The two products at Sephora (to my knowledge) with the highest percentage of retinol are Peter Thomas Roth Retinol Fusion PM (1.5% retinol, $65 for 1 oz) and Dr. Brandt Overnight Resurfacing Serum (2% retinol, $85 for 1.7oz). Skinceuticals also makes retinol products, but they're more expensive and arguably less effective. Note that with any retinol products, you're skin may look worse for the first 1-2 weeks, then it will start to look dramatically better--hang in there, it's worth it!!
Cheers, and good luck!
