Advice on Aloe Vera Gel Formula for Whitening and Moisturizing

Thank you for consulting with us regarding your Aloe Vera gel formula. Let's address your questions one by one.

1. Is this formula suitable for whitening + moisturizing?

Your current formula using Aloe Vera Gel base with Natural Moisturizing Amino Acids, Urea, Snail Secretion, and Hyaluronic Acid Nano is excellent for moisturizing. These ingredients are well-known for their hydrating and skin-conditioning properties.

However, as noted in a previous reply, your current list does not include ingredients specifically for whitening. To achieve a whitening effect, you would need to add active ingredients known for this purpose.

2. How to make a peel-off mask?

To make a peel-off mask that dries and can be peeled off, you need to add a film-forming agent. Gelatin is a commonly used ingredient for this purpose, as mentioned in a previous reply. You would need to experiment with the concentration of Gelatin to achieve the desired consistency and peel-off property. Another ingredient that can provide thickening and some film-forming properties is Pre-Gelatinized Starch, although Gelatin is typically preferred for a true peel-off effect.

3. Should the concentration be higher for a 20-minute sheet mask?

For a sheet mask used for 20 minutes, you generally do not need to use a higher concentration of active ingredients compared to a regular gel or serum. The effectiveness of a mask comes from the prolonged contact time and the occlusive effect of the sheet, which helps keep the ingredients in contact with the skin. The skin's absorption capacity is limited, and using excessively high concentrations might not increase efficacy and could potentially cause irritation. The ingredients in your formula are suitable for absorption during the mask application time.

4. Where can I get the efficacy tested?

Testing the efficacy and stability of cosmetic products is important. To ensure your product doesn't spoil, stability testing (including microbial testing) is crucial. Efficacy testing (e.g., for whitening or moisturizing claims) is more complex and often requires clinical trials or instrumental measurements, which can be expensive. You would typically need to contact specialized cosmetic testing laboratories that offer these services. They can help evaluate the shelf life, stability, and performance of your formulation.

5. Recommended ingredients for whitening + moisturizing and necessary cuts?

Your current moisturizing ingredients (Natural Moisturizing Amino Acids, Urea, Snail Secretion, Hyaluronic Acid Nano) are good and can be kept. To add whitening efficacy, we recommend incorporating well-regarded whitening agents. Some effective options available include:

• Safe-B3™ (Vitamin B3, Niacinamide): Effective for reducing hyperpigmentation and improving skin tone, also offers moisturizing and barrier strengthening benefits. Can be used up to 10%, with 5% being a common effective rate.
• Alpha Arbutin: A potent skin brightening agent that inhibits melanin production. Recommended usage rate is typically 0.2-2%, with 2% being effective for whitening.
• Vitamin C derivatives like Sodium Ascorbyl Phosphate (Vitamin C SAP) or Ascorbyl Glucoside (AA-2G Stabilized Vitamin C) are also good options for brightening and antioxidant benefits.

You could add one or a combination of these whitening agents to your Aloe Vera Gel base formula while keeping your moisturizing ingredients.

6. Recommended mixing order and expected results?

Assuming you are using an Aloe Vera Gel base like Aloe Vera Gel (Heavy) and adding powdered and liquid ingredients:

1. Start with the Aloe Vera Gel base.
2. Add powdered ingredients like Urea, Hyaluronic Acid (Nano Molecule, 800daltons), Safe-B3™ (Vitamin B3, Niacinamide), and Alpha Arbutin. It's often easiest to dissolve powders in a small amount of the water phase (if separating the base) or directly into the gel base at room temperature, stirring well until completely dissolved. Refer to the specific ingredient's mixing instructions.
3. Add liquid ingredients like Natural Moisturizing Amino Acids and Snail Secretion. Stir until homogeneous.
4. Add the preservative, such as PE 1090 Preservative, and stir well.
5. Ensure all ingredients are fully dispersed and the mixture is uniform.

After using a mask or gel with this combination of moisturizing and recommended whitening ingredients, you can expect improved skin hydration, softness, and a gradual brightening effect over time with consistent use.

Remember to always follow the recommended usage rates and mixing instructions for each specific ingredient.
