What it is?

What it does:

With the combination CoQ10, niacinamide, carnitine, and superoxide dismutase, that revitalize and strengthen the skin fibers and replenished dull aging skin for a radiant complexion for a longer period of time.

Type of skin:

Dr Dennis Gross Vitamin C Serum is ideal for all types of skins that desperately in need to brighten up, get rid of fine lines, wrinkles, acne, dark spot, it’s great for dry, oily, normal, or combination of all skin types, but you might need to apply it little by little to see the effect, before you use it fully, if you have a sensitive skin

Though this serum is for the combination of all skins, as long as is a vitamin C serum, acne-prone sensitive skins should use with cautions.

Skincare Concerns:

Dr Dennis Gross serum can treat skin concerns such as, dullness, dryness, dark spots, uneven texture, fine lines and wrinkles leaving you with a plump skin and youthful vitality all day.


Dr Dennis Gross Vitamin C Serum is a brown in color, very thick serum. Though it’s not as thick as a moisturizer, it does have a gel-like feature, and the thickness doesn’t get you irritated, it quickly absorbed and penetrate into your skin leaving you with a lifting sensation.

Immediately it’s absorbed, it leaves you with a tightening and sticky feeling on your face down to your neck, and your décolleté, always endeavor to apply it on the face down to the  low neckline for maximum result.


It’s pretty easy to apply, just like any other face serum, after cleansing pump 1 to 2 drops on your clean, dry face and spread it down the neck, and to low neckline, then give it a minute to absorb and penetrate into your skin before applying any moisturizer of your choice.

As with most face serum applying it twice a day is recommended, but if you’re the outdoor type, you might limit it to once a day at bedtime, because of the presence of the alpha hydroxyl acid, which might not be too comfortable with sensitive skin when it’s exposed to direct sunlight.

Drying Time:

Dr Dennis Gross Vitamin C Serum dries up within a minute of applying it, within seconds you will begin to feel that tightness and sticky effect, before it finally absorb into the skin, leaving you with brighter feeling.


The smell of Dr Dennis Gross Vitamin C Serum is not that really pleasant, I must confess, but with your favorite moisturizer applied after you use the serum can augment for the smell.

My personal advice to my readers, is don’t throw away good product just because it doesn’t smell good, always use a good moisturizer to cover up the smell, if you can’t withstand an offensive smell, go for another face-serums on the market.

For some people that not-too-pleasant smell is better than irritation from a good smelling serum that uses fragrance made by other serums formulators, so know where to draw the line between natural scent and pleasant fragrance smell.

Short Term Results:

When you apply Dr Dennis Gross Vitamin C serum you immediately felt the tightening effect of the serum in your face, neck, and down the low neck. The immediate firmness of the skin is visibly noticed as it you apply the serum overnight.

Within days if you have dark spot, fine lines, wrinkles, or you have acne-prone-skin, you will notice an instant visible difference between before and after you use it, you will also experience a  plump skin as a result of the collagen presence in face serum.

Longer Term Results:

In the long term, you will experience a significant improvement in the appearance of dark spots, fine lines and wrinkles. Long term use turn a dull skin to bright one, slack skin to a  tight one. This is not an exaggeration, I actually experience it on my skin, and the clinical result confirmed it all.

After using the serum for just 28 days, my skin was visibly plump, my acne and sun spots cleared, and it gave me that radiance and luminosity my skin desired, I began to get my confidence back which I have lost a long time ago.

Clinical Results:

The consumer study that was carried out for a period of 3 weeks the following clinical result was recorded:

In the area of quality skin, 92% saw a significant  improvement .

In the area of smooth and soft skin 92% saw a visible improvement

The percentage of consumers that agreed their complexion looked brighter were 83%

Key Ingredients Analysis:

The active ingredients in this potent face serum are the 3 type of vitamin C which merges 3-O C an energy complex (CoQ10, Superoxide Dismutase, Niacinamide, Carnitine) that neutralizes free radical damage, eliminate dark spots and firm your skin.

The most stable and reliable form of vitamin C, (3-O-Ethyl ascorbic acid) assists in reducing the appearance of hyperpigmentation and fine lines to brighten up skin and prevent wrinkles.

Tetrahexyldecyl Ascorbate, it’s an oil-soluble form of Vitamin C that penetrate deeply into the skin easily to fight wrinkles and boost collagen for a firmer and brighter skin.

The Collagen Amino Acid is a plant base collagen and a smaller molecular weight amino acid that supports skin’s natural fibers.

Dr Dennis Gross Vitamin C Serum price is a little bit lower than other price of face serums that does the same work and are in the same categories. 1 oz for $78.00 compare what it does to your skin, I think that is a fair price for a face serum that actually deliver on the results it promised
