Due to the active nature of the ingredients in Environ® products including non-active ingredients which become active when combined with others, a consultation is required to establish the correct products for your skin. A consultation form will be emailed to you after your order has been placed. Please read our skincare policy - we expect all of our customers to follow this policy as these are medical grade products.

Environ Youth Essentia Intensive Serum 4 Plus represents the final step in the Youth Essentia Vitamin Step-up system, and it’s the level you maintain. This formulation boasts an exceptionally high concentration of vitamins A, C, and E, along with antioxidants and peptides.

These carefully combined ingredients synergise to effectively address visible signs of ageing, aiding in skin repair, protection, and normalisation. This, in turn, assists with reducing the appearance of lines and wrinkles, addressing issues of tone and firmness loss, and enhancing uneven skin tone, ultimately resulting in a more youthful, smoother, radiant, and healthier-looking complexion.

This serum is suitable for all skin types, especially mature and photo-damaged skin.

  • Balances and rejuvenates the skin
  • Enhances collagen and elastin production
  • Shields against free radical damage
  • Enhances the look of uneven skin tone, lines, and wrinkles

In both the morning and evening, apply this product to your cleansed face and neck, including the delicate eye area. Afterwards, follow up with Youth Essentia Antioxidant Defence Creme. When using it in the morning, remember to apply sunscreen as the final layer.
