Great Results with Your Gel Formulation!

It's wonderful to hear about your positive experience using Centella Asiatica Extract, Vitamin E, and Extra Virgin Olive Oil in your gel formulation! The results you described, like clearer and brighter skin, are consistent with the known properties of these ingredients.

Here's a bit more about the ingredients you used:

• Centella Asiatica Extract (Madecassoside 7%, Liquid): This extract is well-regarded for its ability to help stimulate collagen production (Type I and III), reduce wrinkles, and improve skin firmness. It also has properties that can help reduce inflammation and redness, and can help reduce melanin production caused by UV exposure, contributing to brighter skin. The recommended usage rate for this extract is typically 1-2%, so your 1% usage is within the effective range.
• Vitamin E (Tocopheryl Acetate): This is a stable form of Vitamin E that acts as an antioxidant, helping to protect the skin from free radical damage. It can contribute to overall skin health and protection. The recommended usage rate for skin benefits is typically 0.1-0.5%, but up to 1% is acceptable, although higher amounts might feel sticky.
• Extra Virgin Olive Oil: Known for its skin rejuvenating and moisturizing properties, olive oil is rich in antioxidants, including Vitamin E and Vitamin A, and beneficial fatty acids. It blends well with the skin and can help improve skin hydration and appearance.

Combining these ingredients in a gel base creates a formulation that leverages the collagen-boosting, anti-inflammatory, antioxidant, and moisturizing benefits of each component, which likely contributed to the clear and bright skin you achieved. It's great that you found a formulation that works so well for you!
