A soothing, skin-conditioning facial serum that combines the age-fighting benefits of C3 Plasma Bio Technology, powerful Vitamin C Esters and age-correcting antioxidants to deliver significant improvements to visible age on the skin. Hydration binding ingredients add volume and smoothness, creating a youthful and more resilient complexion.

How it Works

Gently massage onto a clean, dry face and neck. Allow to fully absorb before applying moisturizer. For external use only. Can be used morning and evening.

Product Benefits

  • Helps reduce visible signs of aging
  • Supports a smoother, brighter complexion
  • Hydrates and plumps skin

Key Ingredients

6 stabilized Vitamin C Esters to repair and diminish visible wrinkles through the rapid stimulation of collagen fibers within the skin. Skin’s elasticity is revived- giving back a firmer, more compact look and the complexion’s brightness is boosted offering a beautiful, luminous clarity.
C3 Plasma™ Bio-Technology: Our exclusive Plasma Technology super-vaporized delivery vehicle suspends the Vitamin C Esters and allow them to saturate the skin’s epidermis for superior absorption and utilization. The warmth of the skin heats the Plasma, infusing the epidermis with high performance anti-agers that can actually stop visible skin-aging in its tracks.

    Serious C3 Serum

    The product is good, byt the price has gone up and it is NOW 1/2 the amount of product from what it use to be. I used it few years back for a couple of years. I can not afford it anymore.

    Great Serum

    I’ve been using this serum for years. I’m in my mid 40s and wanted to incorporate vitamin C into my routine. I’ve tried many different brands and I always come back to this one. I have sensitive skin and the ingredients are gentle. I would definitely recommend.

    I love Serious Skin Care

    It works. I have used Serious Skin Care for decades. It was the first to come out with many of these treatments. Then the others followed. It is also much more affordable than other brands.

    Thank you Serious Skin Care

    C serum

    I use this to add a little moisture to the skin after using the glycolic serum and to boost brightness to the skin.

    C Serum product excellent

    Have used for more than 20 years along with the rest of C Line. Very nourishing to skin. Makes huge difference with my dry, sensitive skin. Please keep the entire Vitamin C line - it is excellent!
