Schäumigkeit:
The Nivea foam longer, has a higher density and is thus fixed. The L'Oréal but can be better distributed.
Odor
The Nivea smell at first really something to Klostein (as in another review mentioned), but the smell evaporates for the most part. The foam adds the smell ago optimally the Nivea Sensitive Shower Gel.
The L'Oréal smells just chemically at first. This smell has nothing to do with the smell Foaming L'Oréal Men Expert Hydra Sensitive cleansing cream for sensitive skin, which I find very mild and pleasant. In the second moment, the smell on the skin nourished but where the cleansing cream.
Gliding
Here wins L'Oreal. It builds on a layer can slide the blade actually better. There are recorded better even in difficult to reach places more robust small hairs.
Complexion
Both shaving help to prevent skin irritations. The L'Oréal is also here a bit far better. There occur no skin irritation.
Skin sensation
The skin is smoother at L'Oréal. It more hairs were collected. The skin feel is natural. It is not quite as "waxed" like the Nivea.
Skin odor
At L'Oréal remains a pleasant odor on the skin.
Conclusion
Both foams fulfill their purpose at a high level. The L'Oréal is the recent development which is in all tested criteria forward. However, one also pays for it. Nivea cost DM and Amazon in 4-pack 1.75 for 200ml. L'Oréal is priced at Müller (available at DM, Rossman, Edeka and Co not) and Amazon in 6-pack 2.95 for 200 ml.
Boss
General has done in shaving foams and blades in the last 10 years a lot. I have used for my sensitive skin to brown 795cc and had the neck always nachrasieren wet without using a shaving cream. With strong growth of beard electric razor in my estimation, are totally unsuitable, though gentle to the skin. Shaving lasts much longer in much worse result. As the new 9 series of brown itself suggests I do not know, but with a Gilette Fusion Proglide and high quality foam to drive more effectively and efficiently, with the shave even has a higher fun factor.
