Differences between Yeast Radiance, Yeast Resurface, and Repair Activator

While all three ingredients are bio-fermentation derived, they come from different sources and offer distinct benefits for the skin:

• Yeast Radiance: This is a protein extracted from a special breed of yeast. Its primary function is to act as a brightener, enhancing skin radiance and giving a clearer complexion without causing irritation.
• Yeast Resurface: This is an oligopeptide obtained from the extraction of specific yeast strains through bio-fermentation. Its main role is exfoliation through skin cell turnover, leading to smoother, more flexible skin, reduced wrinkles, and improvement in dark spots and redness.
• Repair Activator: Unlike the other two, this ingredient is derived from the incubation of Bifida bacteria (Bifida Ferment Lysate). Its key benefit is DNA repair, helping the skin recover from damage caused by UVA light and offering anti-aging properties.

In summary, Yeast Radiance focuses on brightening, Yeast Resurface on exfoliation and renewal, and Repair Activator on DNA repair and anti-aging.

Regarding using all three in an Aloe vera tester, generally, these ingredients are water-soluble and have compatible pH ranges (around 4.0-6.5), making them potentially combinable. However, it is essential to check the specific instructions and limitations of the Aloe vera tester product you are using, as some testers may have restrictions on the type or number of additives.
