Vitamin C

What is it?

One of the most well studied, safest and effective nutrients available, Vitamin C (ascorbic acid) is a nutrient your body needs to form blood vessels, cartilage, muscle and collagen in bones.  As our bodies do not naturally produce vitamin C, we usually get them from fruits and vegetables, including oranges, strawberries, kiwi fruit, bell peppers, broccoli, kale, and spinach.


Vitamin C is a normal skin constituent that is found at high levels in both the dermis and epidermis. Aging, however, causes a decline in vitamin C content in both the epidermis and dermis. Excessive exposures to UV light or pollutants (e.g., cigarette smoke and ozone) will also lower vitamin C content, primarily in the epidermis.


Benefits:

  • Boost collagen and ceramide production
  • Essential for collagen synthesis
  • Improves skin health
  • Strengths immunity
  • Manage blood pressure
  • Reduce risk of chronic illness including dementia and heart diseases

    Summary of Select Clinical Studies:

    • When combined with collagen, it increases collagen synthesis, accelerates bone healing after a fracture and reduces oxidative stress 1
    • Encourages production of white blood cells, boosting immunity 2
    • Shortens healing time 3

        GEST, short for inGEST, was formed by three best friends on a mission to create thoughtful supplements that make our world healthier and wealthier.

        Like many people reading this right now, the three of us struggled with skin issues and approached the concept of aging skin with a vague sense of anticipation and confusion. In our path towards wellness, we attempted clean diets, nearly half of the product catalogs at Sephora and Target, and of course, skin supplements.

        After two years of experimenting with skin supplements, we were thousands of dollars poorer and had little to show for it other than bad reactions with acne flares and even digestive issues. Supplements really do suck, we thought. But, our minds changed when we stopped searching for miracles cures and instead learned to ignore false marketing and instead focused on studying the science behind the supplements.

        Guess what? Dietary supplements really do work, gigabytes of lab data and research prove so (our own glowing skin, hair, nails agree). The market is just saturated with not-so-great products that are heavy on marketing and light on substance.

        That’s where SKINMUNE comes in. A great skin supplement only works when it’s the right formulation with correct dosages of active ingredients, and when consumed as a routine. We are so excited to bring to you SKINMUNE, which was formulated with experts and developed over the course of a year working closely with our early beta users.

        We’ve combined the best clinically-proven ingredients to launch GEST SKINMUNE (skin + immunity). The first formula of its kind, sip these daily to see supple, plump, hydrated skin.
