Melatonin in Facial Serum and Microemulsion Cleanser

Here is the information regarding your questions:

1. Pure-Melatonin™ in Facial Serum and Facial Hair Growth

Pure-Melatonin™ is known for its powerful antioxidant properties and benefits for skin aging, such as improving the skin barrier and helping to maintain collagen. While research indicates that topical Melatonin can stimulate hair growth and reduce hair loss, particularly in the context of androgenetic alopecia on the scalp, its primary effects when used in facial serums are generally focused on skin health and anti-aging. It is unlikely that using Pure-Melatonin™ in a facial serum at typical cosmetic concentrations would cause significant unwanted facial hair growth. The hair growth stimulation effect is more specifically observed and studied for scalp applications.

2. Microemulsion Cleanser Formulation

• Oilsify 30 vs Oilsify 15: Both Oilsify 15 and Oilsify 30 are designed as oil-emulsifiers for cleansing oils and can effectively remove makeup. However, the product description for Oilsify 15 specifically notes that a Microemulsion Cleanser formulation using Oilsify 15 can provide better cleaning performance, especially for makeup removal, and may require a higher concentration for optimal results compared to other formulations. Your experience suggests that Oilsify 30 at 30% was not as effective for waterproof makeup, which aligns with the indication that Oilsify 15 might be the preferred choice for achieving superior makeup removal performance in a microemulsion system.

• Suitable Natural Oil (Non-Comedogenic): For the 50% oil phase in your Microemulsion Cleanser formula, you need a non-comedogenic natural oil. Based on product information, Squalane (Olive) is an excellent choice. It is described as suitable for all skin types, especially acne-prone and sensitive skin, absorbs quickly, and helps moisturize without feeling heavy. This makes it a good option for a cleansing oil that is less likely to clog pores.
