Homemade Formulations and Ingredient Availability

Regarding making your own lotions, toners, etc., without preservatives and using them within 1-2 months:

While it might be possible under extremely strict hygienic conditions and proper storage (like refrigeration), it is generally not recommended to omit preservatives entirely, even for use within 1-2 months. Cosmetic formulations, especially those containing water or natural ingredients, are susceptible to microbial growth (bacteria, mold, yeast) from the environment, ingredients, or contact during use.

Factors that increase the risk of contamination include:

• Lack of strict sterile procedures during mixing.
• Ingredients that provide nutrients for microbes (especially natural extracts).
• Storage conditions (room temperature is higher risk than refrigeration).
• Packaging and usage (e.g., dipping fingers into a jar introduces microbes).

Using a suitable preservative helps ensure the safety and stability of your product throughout its intended shelf life. For homemade products, especially if you are new to formulating, using a mild preservative is highly recommended. Options like Mild Preserved Eco or NaturePreserve Ultra are available.

Regarding Pro Niacin (Myristyl Nicotinate):

The product Max-B3 (Myristyl Nicotinate) is currently out of stock. We apologize for any inconvenience this may cause.

Regarding the new Plankton product:

Based on the available information, there are different types of plankton extracts. Plankton Artemia Extract is known for properties similar to those used in brands like La Mer (often compared to Biotherm/Sena). The new Marine Plankton (Lifting, Tightening) appears to be a different type, focusing on immediate and long-term lifting and wrinkle reduction effects through polysaccharides, and is likely the one you are referring to as being different.
