Ferulic C Antioxidant Serum 20%

My favorite C serum. Have tried several others. PureCeuticals serum has 20% C, which experts advise is the most effective concentration.It does not turn into a peel on my skin, which others did. Before this C serum, I had to wait several hours, after using a serum, before applying makeup or even moisturizer, to prevent it from all peeling off as I tried to add on. This does not happen with PureCeuticals serum. Instead it soaks in, and I can add more layers immediately.Slows the appearance of spots and eliminates occasional breakouts on my not-so-young skin. One small keratosis shrunk and disappeared, over several months, after I started using this serum daily. Keeps my skin generally clear and brighter.Of course, careful storage is important to preserve ingredients - cool and out of the sun is best.Helpful and responsive seller. Contact directly through Amazon.The negative ratings confound me. Not one of them has actually left a review to explain their lower opinions. One never knows what to make of unexplained ratings, good or bad, at Amazon. Maybe the old system of reviews only was preferable.

I should say, 'too soon to tell', but it seems like pricey products I've used before.

Excellent product, use in conjunction with retinol and lactic resurfacing.

Yes, yes and yes :) worth it!

Pure Ceuticals Ferulic C Antioxidant Serum is the product you can't wait to use as you go through your nightly [or morning] routine. The serum slips gloriously into your skin, leaving no residue - just a well-loved, well-fed feeling. You will definitely feel the difference!
