Suitability of Ingredients for Under-Eye Area

Based on the product descriptions, here is a breakdown of each ingredient:

• Aloe Vera Extract (extraction ratio 10:1 FullAssay™): This extract is described as helping to condition the skin, reduce allergic irritation (especially sunburn), and moisturize. Its usage is indicated for wrinkle-reducing products in various forms like gel, serum, lotion, or cream. These properties make it suitable for the delicate under-eye area, which often requires hydration and soothing.

• Pure-Genistein™ (Soy Extract (Genistein 98%)): The description for this product explicitly states that it is "For food/pharmaceutical research use only" and "Currently, the Thai FDA does not allow its use in dietary supplements." While Genistein has properties related to phytoestrogens and potential benefits for dry skin, the product information indicates it is not intended for cosmetic use, particularly in a sensitive area like under the eyes. It is strongly advised not to use this ingredient in cosmetic formulations based on this information.

• Natto Gum (Nutto Gum): This ingredient is highlighted for its high effectiveness in providing moisture, even more so than Hyaluronic acid according to research results. It also helps to gently whiten the skin and is suitable for skin care products. Its strong moisturizing and gentle whitening properties make it suitable for addressing dryness and potentially dark circles under the eyes.

• Madecassoside (Centella Asiatica Extract): This high-concentration Centella Asiatica extract is known for stimulating collagen production (Type I and III), reducing wrinkles, tightening skin, and helping with scars and redness. It is effective in reducing skin inflammation and can help reduce melanin pigmentation caused by UV-induced inflammation, which contributes to dark spots. It is widely used in anti-aging cosmetics and wrinkle products. Its anti-aging, collagen-boosting, anti-inflammatory, and potential dark circle reducing benefits make it highly suitable for under-eye formulations.

In summary, Aloe Vera Extract, Natto Gum, and Centella Asiatica Extract (Madecassoside) appear suitable for use in under-eye products due to their moisturizing, soothing, anti-aging, and potential dark circle benefits. However, Pure-Genistein™ is explicitly indicated for research purposes only and is not suitable for cosmetic application.
