Jan Marini Skin Research C-ESTA Serum - Antioxidant-Rich Beauty Product for Dry, Oily & Normal/Combo Skin - Lifting & Firming Serum with Vitamin C - 1 fl oz

I am a licensed esthetician and this is one of my favorite Vitamin C formulas. It is a gentle, yet effective form of Vitamin C. I have combo, acne-prone and sensitive skin. It has a bit of a floral scent that I ended up getting used to.

I first purchased the kit from my dermatologist.When I saw that Amazon offers it too, I decided to purchase the products here because of the convenience. Price is the same but I get it delivered to my front door.Do you want to know if it works? Well, judge for yourself. This picture (for work) is me after 6 months of using the product. BTW, I turned 75 in December.

I'm 35 and have been seeing an esthetician for several years who carries Jan Marini's skincare line. She uses this C-Esta Serum during my monthly facial, and it is so amazing for brightening my complexion and giving me smooth, even, dewy, radiant skin!Buying a bottle of this product was a splurge for me. It's typically around 100 bucks, which is more than I want to spend on a single skincare product. However, I couldn't refuse Jan Marini's 20% off Black Friday sale here. I bought it directly from Amazon, not a third-party seller, and the product is perfectly fine, smells right, has the correct consistency, etc., exactly the same as what I've purchased from my esthetician over the years (and yes, sometimes it's grainy).C-Esta really does lift and tighten. I always notice in the bathroom mirror how my pores appear smaller a few minutes after applying this serum.The dispenser pump works well. A bottle lasts me several months. The product is indeed watery in consistency and smells a bit like flowers + tropical fruit. It's hard to describe, but it smells amazing. Really happy to have scored this for a discount.

I have been using it for years.

Love it work perfectly with my skin!

Been using this product for 20 years. As a skincare specialist, I recommend C-Esta Serum for daily use. A silky feel and a visibly brightener skin.

Pattern Professional sold me this Jan Marini C-Esta product via my Amazon Prime account in late March of 2024. (see 2 photos). In Jan. 2025 I discovered that the bottle they shipped me had a false bottom, allowing the bottle to be filled to only about 1/6th of normal 1Fl ounce bottle fill. Two holes were drilled into the bottom cap, done after an adjustable interior slide-tube containing the C-Esta had been inserted, and pushed way up to the top, thus allowing filling of product to only a fraction of the normal 1Fl ounce amount. I discovered it because the product ran out way before it should have. When I saw the drilled holes in the bottom cap, I suspected this, and proved the point by sliding it up and down using a Q-tip to push down, and a straightened paper clip to push it up. I posted a review on this site on Jan. 12, 2025, plus contacted Pattern Professional, but never heard from anyone, and the review never posted. I never got any refund for the $133. spent.

Definitly makes my skin more clear.
