I've come to truly believe that high-quality products do not need to be complicated and packed with long ingredient lists. Instead, a formulation can be simple and very effective, holi (c) is an example of this, containing just two ingredients: calcium ketogluconate and sodium ascorbyl phosphate. I have searched the world for the most effective pure, non-GMO ingredients, and I love what we developed with holi (c). holi (c) is a dry, stable form of Vitamin C powder (known as Sodium Ascorbyl Phosphate that I will refer to as SAP) that is the most stable, potent state of Vitamin C. The SAP is deeply regenerative and is combined in this product with Calcium ketogluconate, a French-patented natural complex molecule that helps restore the skin's elasticity for a youthful, plump appearance. Nearly all Ascorbic and L-Ascorbic Acid is derived from GMO corn, but at Agent, we source our non-GMO SAP from Japan and France, which have the highest safety regulations for cosmetics in the world. Not only is GMO sourcing dangerous to our health, but Ascorbic Acid is complex for the body to absorb through the lipid barrier so poor quality products often don't do much to your skin This holi (c) bottle looks small but lasts me four to five months. The reason for this is because of the potency and quality of the formulation. Most formulations of Vitamin C on the market only have 0.5 - 5% vitamin C in their products. One bottle of holi (c) could formulate up to 100 bottles of serum if I were to formulate it out into liquid form. What are the benefits of using holi (c) in your skincare routine? -Anti-aging and redness-reducing properties -Protection against UV rays and sun-related aging -Hyperpigmentation and dark spots -Anti-inflammatory and acne fighting I recommend pairing it with our holi (water) to get the maximum benefits of the lavender water, cucumber water, the powerful antioxidant and mineral content of the pearl powder, and the unmatched brightening effects of pitaya.
