All products of Nivea-series have already been used. All protect a day well before sweaty armpits and prevent perspiration odor. Since we could not even notice a difference in the fragrance in the action, the Nivea deodorants are thoroughly recommended. This "Dry Impact" promises "extra protection". What is the settled unfortunately neither find nor notice in daily use.
On the subject of aluminum which has come under criticism: There are researchers who consider aluminum is dangerous and suspect that it may be responsible for breast cancer or Alzheimer. Others doubt that. Since it is still unclear whether aluminum is harmful or not, I regard the ingredient not from. Ultimately, everyone must decide whether he wants to take the (perceived) risk in buying or not.
MY CONCLUSION:
Effective deodorant with the typical bitter Nivea scent. Prevented by clear consistency reliable white spots on dark T-Shirts, yellow spots are not completely prevented. Although the promise of "extra protection" compared with other Nivea deodorants can not be established, it is a reliable anti-perspirant and acting is recommended!
