What's Inside Vitamin C Serum

Supplement Facts

Citrus Stem Cells

Citrus stem cells are derived from oranges and help to rejuvenate and revitalize the skin. They promote cell regeneration, support skin elasticity, and help reduce the appearance of fine lines and wrinkles, for a youthful and radiant glow.

Hyaluronic Acid

A derivative of hyaluronic acid, sodium hyaluronate is a powerful humectant that attracts and retains moisture in the skin. It deeply hydrates, plumps, and smooths the skin, reducing the appearance of fine lines and wrinkles.

    • How Can I Get the Best Results from Vitamin C Serum?
      For the best, brightest results, consistency is key, so be sure to use Vitamin C Serum once in the morning and then again before bedtime. Additionally, for maximum skin benefits, we recommend regularly wearing a sunscreen with an SPF of at least 30.
    • What Can I Expect with Vitamin C Serum?
      Vitamin C Serum is a scientifically advance serum, that’s loaded with antioxidants and high-tech glow boosters. With regular use, you can expect brighter, glowier, younger-looking skin. Even better, the serum has a silky-soft texture that penetrates the skin without stickiness or pilling. Natural Caribbean Orange Oil gives Vitamin C Serum its fresh, citrus scent.
    • Doesn’t Vitamin C Break Down When It’s Exposed to Light, Water, or Air?
      It’s true that Vitamin C can be finicky, quickly degrading when exposed to light, water, or air … this can render some serums useless or worse, cause blackheads, staining, irritation, and other unwanted effects. Fortunately, Vitamin C Serum uses Sodium Ascorbyl Phosphate, a highly effective form of Vitamin C that’s oxygen, light, and water-stable, so you can enjoy the brighter, glowier skin you desire … without worrying whether you’re doing your skin more harm than good!
    • I Have Sensitive or Acne-Prone Skin. Can I Still Use Vitamin C Serum?
      Vitamin C Serum is non-greasy and formulated with a gentle but effective form of Vitamin C that’s well-tolerated by most skin types. Additionally, Vitamin C Serum contains Hyaluronic Acid and Chamomile, two nourishing ingredients that calm and soothe skin. However, if you’re concerned about a possible skin reaction, we recommend spot-testing Vitamin C Serum on a small area before broadly applying it.
    • Can I Use Vitamin C Serum with Dark Spots Corrector?
      Yes! Vitamin C Serum and Dark Spots Corrector can be used together twice daily for maximum skin brightening and anti-aging effects. Simply apply Vitamin C Serum to your skin first, followed by Dark Spots Corrector—am and pm.
    • How Do I Use Vitamin C Serum?
      Apply 1-2 pumps of serum twice a day to fingertips, then gently massage on face, neck, and chest. Give Vitamin C Serum 1-2 minutes to absorb before applying sunscreen and/or moisturizer.
    • Is Vitamin C Serum Safe?
      At Clinical Effects, all of our products are created in an FDA-Regulated laboratory that has strict quality controls in place. The FDA considers all of the ingredients used in Vitamin C Serum to be generally safe. While everyone’s body is different, very few customers report negative side effects.
    • What Else Should I Know About Vitamin C Serum?
      Vitamin C Serum is formulated with natural ingredients. Our glow-boosting serum is vegan-friendly, hasn’t been tested on animals, and is free of alcohol, parabens, and sulfates. Additionally, unlike a lot of other skincare products, Vitamin C Serum is made right here in the United States.
