Formulation Questions Answered

Here are the answers to your questions regarding cosmetic ingredients:

• Long-Lash™ Usage: Yes, Long-Lash™ can be used on other hair-bearing areas such as eyebrows, sideburns, and beard. It contains peptides designed to stimulate keratin genes and hair growth, which is the mechanism for its effect on eyelashes.
• Active Resveratrol and Reservoir-Tech: Yes, these two ingredients can be used together. Reservoir-Tech functions by forming a film on the skin to help retain active ingredients and release them gradually, which can enhance the effectiveness and reduce potential irritation of compatible actives.
• Penetration Enhancer for Activated Resorcinol S + Resveratrol: For a combination of Activated Resorcinol and Resveratrol, Phospholipid is the recommended penetration enhancer. Activated Resorcinol is oil-soluble, and while Resveratrol comes in different forms (some water-soluble, some not), Phospholipid is suitable for carrying both oil-soluble and water-soluble ingredients. Reservoir-Tech is not recommended for oil-soluble actives like Activated Resorcinol.
• Applying Activated Resorcinol after AHA: Applying a cream containing Activated Resorcinol after using AHA (like 12% at pH 3.5) is not recommended. The acidity of AHA can negatively affect the quality and stability of Activated Resorcinol.
• Encapsulated Vitamin C: Currently, there are no plans to sell Encapsulated Vitamin C on the website.
