How Vanuatu volcanic ash and walnut shell powder polish skin in Facial Resurfacer — Fine Vanuatu volcanic ash and walnut shell powder polish skin while botanical oils leave it soft. Facial Resurfacer pairs fine, near-spherical Vanuatu volcanic ash, selected about 1.5 km downwind of Mount Yasur, with walnut shell powder, Nangai Seed Oil and seaweed extract.

Where does the volcanic ash come from?

In Facial Resurfacer, finely textured, mineral-rich Volcanic Ash from Vanuatu works beside Juglans Regia (Walnut) Shell Powder to exfoliate and polish dry, dull surface cells. SeneGence selects Vanuatu volcanic ash from a downwind deposit approximately 1.5 kilometers from Mount Yasur's active vent. During that airborne journey, larger fragments settle sooner, helping concentrate a finer particle range farther from the vent; the material chosen for SeneGence is selected for a near-spherical particle profile. Fine, rounded grains polish rather than scrape, which is why SeneGence chooses this Vanuatu material for the face. See where the ash comes from or why Facial Resurfacer uses it.

How often should you use it?

A little goes a long way. Gently massage Facial Resurfacer onto clean, moist skin using light circular motions. Avoid eyes, rinse well, and use it twice per week or on an as-needed basis. Facial Resurfacer.

Volcanic ash also appears in Smoothing Body Scrub, a body formula SeneGence sells in Mexico that pairs it with pumice; for the face, Facial Resurfacer pairs the ash with walnut shell powder. For the story behind the ash, see what Joni Rogers-Kante discovered in Vanuatu.
