A serum is a treatment. Always follow a serum with a moisturizer.

This product is in a silicone base (Cyclopentasiloxane, Cyclomethicone) that will absorb oil and provide a matte effect to your skin. However, as silicone sits on top of your skin (and is not absorbed) I would consider using a moisturize prior to this product.

I used this as a moisturizer, but my skin is mostly normal...if you have dry skin, though, you may need an additional moisturizer.

I use this exclusively as my evening moisturizer. I find that it hydrates just enough. I haven't used in in the am, but I'm very pleased with it as an evening treatment.

I don't think so... it doesn't have much moisture in it. It's more of an oil-absorbing lotion.

It used to be recommended to apply Vit. C in the AM and Retinol PM because skin is more sensitive to Retinol. Today, many derms still abide by this, but some are saying the opposite, and that you can even use them together. It's very difficult to know what to do sometimes with all of this conflicting info. I am still a believer in the C in AM and Retinol in PM, but regardless, SPF of at least 20 or greater should be on the face (and body, of course) .

Usually, 1-2 pumps, depending on the area of coverage. (some of us have smaller faces than others). Put the serum on the fingertip and dot each cheek, then glend. (Don't rub it into your palms first, you're just applying most of the product to your hands). Most all serums smooth on quickly and evenly; don't rub.

Question
Why is it recommended to use product in pm? and not am?
I've been using this product in the morning - as it also works as an excellent primer beneath my foundation and sunscreen. I know that products containing vitamin C make you more sensitive to the sun and that when using these products you must use sunscreen. Otherwise, are there any benefits to using this product only in the evening as recommended?

Because when used in the AM, there's the likelihood of the vitamin C being broken down by exposure to sun, thus reducing the effectiveness of this serum.

I think it's mainly b/c MD recommends using the Antiox Firming Serum during the day. I guess it's a complimentary approach, I don't think it's mandatory, though.

I think it is ok for acne. I had acne back when I used this, and it actually seemed to help it. the problem with this product is the packaging/pump. It seems at a cost so high, it would actually work and you could get more out of it before the pump goes dysfunctional. I ordered it twice and it didn't last more than a month either time.

Amazing for acne treatment! It has Glycolic and Salicylic acids to get rid of blemishes and then Vitamin C and Phytic acid to brighten the scars.

Can this be used under makeup to absorb oil?
I have EXTREMELY oily skin and hate the feel of dimethicone type products, which I see this contains yet I read a lot of people say this absorbs oil. To those of you with oily skin, could you use this under makeup to help control oil? Does it have that 'slick' dimethicone feel?

I have a very oily t-zone, and I find that using this product controls oil all day! Better than all the pore-filler, anti-shine products I've ever used and that I no longer need thanks to this product! I put this serum on at night, and when I wake in the morning, skin is not oily at all. I have been using it AM and PM.

The instructions for this product say it is for pm use and so I only use it then. It does have that slippery dimethicone feel to it and I don't think it would do very well to absorb oil under makeup.

Yes, this product contains ascorbic acid. It is also useful to note that it contains two other forms of Vitamin C: sodium ascorbyl phosphate, and ascorbyl palmitate. The product advertises 18% Vitamin C, but there's no way to know how much of that 18% is ascorbic acid.

It may help to have the three different types of Vitamin C. Ascorbic acid has the strongest antioxidant effects, but it deteriorates with exposure to air and light. The other two types are more stable in the air and light, and have increased absorption into skin, but they aren't as effective. Using all three together may cast the widest net for good results.

Hope that helps!

On Dr. Dennis Gross' website at http://www.dgskincare.com - this product claims to have an 18% Vitamin C complex (multiple forms of vitamin C). Must say that is very good and much higher than most products on the market.

I am dissapointed that a company such as Dennis Gross MD does not advertise the percentage of vitamin C in their product. I too loved this product but was not certain that it contained a high enough percentage of vitamin C to be effective. I will try to contact the company directly, and if successful will post their response here.

Question
Extra sensitive and dry mature skin....is this product too strong!!
I have extremely sensitive skin, very, very sensitive, that is also on the dry side. I am 64 and up until about 6 months ago I had a beautiful peaches and cream complexion. Then one day I saw the sign...a few dark spots were starting to show on my cheeks. I tried a product...Pro Activ skin lightening gel. It has 2% hydroquinone and 4% glycolic acid. Boy, this product ate my skin!! My skin became raw, drier, and it left me with burning feeling. Now that my skin has calmed down, I am looking for a great product that will help stop these spots from getting darker and prevent new spots. As I said I am 64, very fair, and no lines or wrinkles. I know Vitamin C is excellent. I can't use anything with any form of retinol, AHA's or BHA's or any acids. I sure could use some help!! Any suggestions would certainly be appreciated!!!!

I, too, am in my sixties. The only products I find that can be too strong for some are the single-ingredient serums, such as Retinol or Vit. C serums with hi-potency. If you use these, you start out with light application and see if your skin reacts. If so, decrease the product use to every other day, or as tolerated until your skin gets used to it. Multi-ingredient products as a rule, do not tend to cause much sensitivity, but if so, do as above. As for the extra dryness, especially at our age, you would likely need a moisturizser following the serum (after it has been absorbed)
