        My skin was looking dull from years of sun exposure making me feel like I looked older than I am. After using this for 3 months it looks brighter and younger. I look like myself again. I just ordered 3 more bottles.

      • 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.
