How it works C-Tetra

  • C-Tetra protects and helps to stimulate the synthesis of new collagen and elastin, causing the skin to tighten and reducing minor lines and wrinkles
  • C-Tetra is a potent Vitamin C antioxidant serum that is 100% stable, super-absorbent and non-greasy
  • C-Tetra contains Vitamin E which apart from being an antioxidant itself, recycles the Vitamin C to boost the overall antioxidant effect
  • The C-Tetra formula is highly bioavailable

Retinol 3TR

  • Retinol 3 TR visibly regenerates the epidermal layer of the skin, encouraging a smoother appearance of face contours, through stimulated production of collagen and elastin
  • Retinol 3 TR helps to refine skin tones and brighten up darker patches on the skin by accelerating the natural peeling of the corneocytes
  • Retinol 3 TR unblocks the hair follicle pores and regulates the sebaceous glands’ activity for anti-blemish and comedolytic benefits – the formation of comedones, also known as blackheads, becomes largely inhibited leading to a clearer, less congested complexion.
  • Encapsulation of retinol molecules, low skin irritation
  • Time release delivery system (controlled and gradual release of active ingredients)
  • Ground-breaking stability data (shelf life of 24 months, period after opening of 12 months)
  • Short batch runs for maximum stability
  • Non-acne aggravating and non-comedogenic (does not clog the pores)
  • Contains 0.3% retinol supported by tocopherol acetate for significantly enhanced stability as compared to other retinol products

Physical Sunscreen

  • Zinc Oxide/Titanium Dioxide – broad spectrum protection from UVA & UVB exposure which also heals, soothes and calms the skin
  • Thiotaine – a naturally occurring antioxidant and amino acid stimulated in the body due to UV radiation; recycles vitamin C assuring efficient energy production and inhibits tyrosinase
  • Marrubium Vulgare Extract – a highly effective natural antioxidant which protects skin from the absorption of environmental pollutants. It also strengthens the skin’s barrier and cell metabolism
  • Carnosine – provides anti-glycation and anti-infrared protection to prevent environmental damage to the skin cells. Acts by scavenging free-radicals and neutralising them
