Formulation Advice

Based on the formulas you provided and the information available, here is some advice:

Mixing Ingredients into Aloe Vera Gel

Yes, ingredients can generally be mixed directly into Aloe Vera Gel bases. Products like Aloe Vera Gel (Heavy) and Aloe Vera Gel (Lite) are designed as bases that can be easily combined with other active ingredients, whether they are powders or liquids. You typically add liquid ingredients and stir until homogeneous, while powdered ingredients may require stirring, resting, and stirring again to fully dissolve.

However, it is important to note that some specific types of Aloe Vera Gel bases, such as Aloe Vera Gel (Lite), list incompatibilities with certain ingredients, including Double Hyaluron Liquid. While the staff confirmed your original Hada Labo formula (Aloe Vera Gel 94%, Double Hyaluron Liquid 6%) is mixable, it is always good practice to check the specific product description for any base you are using for potential incompatibilities.

Your Formulas

• Eye Gel Formula: Your eye gel formula includes Aloe Vera Gel, Orange Peel Extract, Centella Asiatica Extract (Madecassoside), and Repair Activator™. These ingredients are well-suited for an eye gel. Orange Peel Extract (specifically Hesperidin Methyl Chalcone) is known for stimulating blood flow to help reduce dark circles around the eyes. Centella Asiatica Extract (Madecassoside) can help stimulate collagen production and reduce inflammation, beneficial for the delicate skin around the eyes. Repair Activator™ (available in versions like Repair Activator™ BG and Repair Activator™ WS) is used for its potential in skin DNA repair, contributing to anti-aging effects.

• Hada Labo-like Formula Modification: You asked about adding Tranexamic Acid (Trans-White™) to your Aloe Vera Gel and Double Hyaluron Liquid formula to treat melasma. As the staff correctly advised, Tranexamic Acid (Trans-White™) is effective for brightening skin and reducing blemishes caused by sun exposure. It can be used in face and body formulations at concentrations up to 3% for cosmetic purposes. Your proposed concentration of 3% is within this limit. However, it is not recommended for use around the eyes or lips due to potential irritation. Therefore, while the modified formula is suitable for treating melasma on the face or body, it should not be used as an eye product.

In summary, mixing ingredients directly into Aloe Vera Gel bases is a standard practice, keeping in mind potential specific incompatibilities. Your eye gel formula uses appropriate ingredients for that area, and your modified Hada Labo formula with Tranexamic Acid (Trans-White™) is suitable for face/body melasma treatment, but avoid the eye area.
