Concentrated, hydrosol-based face serum with Vitamin C in an active strength of 10%. It has a light texture that blends perfectly into the skin. An energizing boost of antioxidants that effectively brightens tired complexion. Studies have shown that C-shot reduces skin roughness by 30% after 4 weeks of regular use. It also reduces sebum secretion by 23.3% and restores silky smoothness.

Ewa (in the photo), our Social Media Specialist with combination and hyperpigmented skin: "I find the serum works best with my morning skincare routine, applied under my sunscreen. It's a great antioxidant treatment to strengthen my capillary skin. C-shot restores its luminous glow."

Key active ingredients:

10% of stable form of Vitamin C (3-O-Ethyl Ascorbic Acid) - this derivative is resistant to high temperature and light. It is an excellent antioxidant - it eliminates free radicals, preventing premature skin aging. Stimulates collagen synthesis and is very well tolerated by the skin. Gently brightens and inhibits the synthesis of melanin, which is responsible for the formation of discolouration.

Hyaluronic Acid (ultra low molecular weight) - is biocompatible and deeply moisturising. The content of natural HA in the skin decreases with age and leads to dry skin. One molecule of HA in the serum is able to bind about 250 water molecules. It increases the level of hydration in the stratum corneum.

Redivine® - grape leaf extract - has anti-pollution and anti-blue light properties. Eliminates free radicals, promotes soothing irritation, improving skin firmness and elasticity.

20% of Geranium Hydrosol soothes irritations and supports the care of capillary skin.

Dipotassium Glycyrrhizinate (glycyrrhizin from licorice root) - has soothing and anti-inflammatory properties. Supports skin regeneration, reduces redness and irritation.

Results of application tests conducted on a group of probands:

  • nourishes and soothes dry skin (85% of responses);
  • provides a regenerated skin effect even after prolonged fatigue (75% of responses);
  • corrects sun and acne discolorations (70% of responses).

Apparatus test results (after 4 weeks of regular application):

  • wrinkle level reduced by 23%
  • skin roughness reduced by 30%
  • skin smoothness increased by 20%
  • sebum secretion reduced by 23.3%.

Is it safe to use vitamin C serum in the summer? ~ Absolutely, vitamin C, especially its stable derivative, is beneficial for summer care and does not have a photosensitizing effect. However, we believe that sun protection is a good idea at any time of the year - when applying during the day, we recommend applying a sunscreen.

Does the serum weigh down the skin? ~ when tested by an independent laboratory, 90% of test subjects declared that it does not weigh down the skin and 95% declared that it does not clog pores. C-shot has a light, watery texture that quickly melts into the skin.
