Skin Brightening Ingredients

Regarding your question about adding Vitamin B3 to the green Bhaesaj lotion, as the exact concentration of Vitamin B3 in the existing lotion is unknown, it is not recommended to add more. Doing so could potentially lead to using a concentration higher than safe levels, which might cause skin irritation.

You can certainly use the Vitamin B3 you have for your new facial product formulation, where you can control the concentration precisely.

For your new formulation, if you are looking for other ingredients to enhance skin brightening, especially alongside Vitamin B3 or as alternatives, here are a few options with different mechanisms of action:

• GlucoBright™ (Acetyl Glucosamine): This ingredient works synergistically with Vitamin B3 (Niacinamide) to reduce dark spots and brighten skin. It also helps stimulate the skin's natural production of Hyaluronic Acid, providing moisture and helping to reduce wrinkles. It's water-soluble and generally used at 1-8%, with 4% recommended in combination with Niacinamide (Vitamin B3) at 2-4%.
• Activated Resorcinol™ (4-Butyl Resorcinol) / Phenylethyl Resorcinol (e.q. SymWhite 377): These are potent tyrosinase inhibitors, meaning they effectively reduce the production of melanin pigment. They are considered highly effective for overall skin brightening and reducing dark spots and melasma. Both are compatible with Vitamin B3 and N-Acetyl Glucosamine. Activated Resorcinol™ is typically used at up to 1% in leave-on products, while Phenylethyl Resorcinol is recommended at around 0.5% for leave-on products.
• MSH White™ (Undecylenoyl phenylalanine): This ingredient works by reducing Alpha-MSH, a molecule that stimulates melanin production. It's effective for brightening and reducing age spots and works well when combined with other whitening agents like Vitamin B3 or N-Acetyl Glucosamine. Usage rate is typically 0.5-2%.
• Tranexamic Acid (Trans-White™): This is effective for reducing melanin formation, particularly helpful for blemishes caused by sun exposure. It is water-soluble and can be used at up to 3% in cosmetic formulations.
• MelaninTerminate™: This ingredient, derived from pearl protein, offers a unique mechanism by blocking the endothelin receptor, which prevents melanin formation. It's used at a very low concentration (0.01-0.1%) and is water-soluble.

When formulating your new product, you can choose one or a combination of these ingredients, considering their recommended usage rates and compatibility, to achieve the desired skin brightening effect.
