Effective 48H, Hypoallergenic For the first time, NARTA integrates Magnesium Oxide in its antiperspirant’s formula. Magnesium, naturally present in the skin, gives your skin a maximum protection against humidity. NARTA’s Magnesium Protect antiperspirant roll-on deodorant offers a 48-hours antiperspirant protection, doesn’t contain alcohol, and is as effective as aluminum salts against odors. Its hypoallergenic formula is dermatologically tested on sensitive skin and respects the natural mechanism of perspiration.
