Experiment with things
As far as protection invisible? Decided to check this action. Whether the deodorant leaves some marks on black fabric on white things? 
If just to spray on them – that is not present. You will tell that it not the proof. It agrees. It only proves that there is no talc in structure and means without color. Because, for example, dezik with talc imprints on black at once, and the yellowish structure too surely leaves a mark on white.
It is necessary to wear a thing. What I also do. Carried both a black top, and white (they against the background of). On them did not find any traces.

Condition of skin
Not only protection against sweat, but also care of skin armpits has to be one of the main properties of any deodorant. We not often pay attention to it, we will tell directly. But if you found a good deodorant – know that how skin after it feels.It should not be rough, angry. Dryness, darkening or on the contrary clarification – also not really good indicators of quality of a deodorant.
After Nivea Invisible protection skin remains well-groomed. It was pleasant to me. Did not notice irritations, after all the product dermatological is tested, I trust it.
Smell
One more quality which is important for a deodorant. It is its aroma or lack of a smell. In fact, the antiperspirant does not need a fragrance, it influences sweat glands, but does not mask a sweat smell. But Nivea made correctly that it added a fragrance. Most of women have a classical idea of a deodorant – it has to have aroma, - they consider.As retreat. I read a research (focus group polls) which made the agency cooperating with other available deodorant in the market (from the famous American producer). Price category – same, as at Nivea. And in this market research interesting conclusions were drawn. First, despite a large number of roller and cream deodorants, more than a half of women prefer deodorants in sprays. It was told about feelings of freshness in the mornings and effect of "shower". Secondly, existence of aroma is important practically all respondent. In Russia of supporters natural there is not a lot of all, and nobody wants to use starch or soda. There were also conclusions about packing – women were given at choice bottles of different flowers and designs, but they chose white bottles as a symbol of purity and good hygiene.

This example with a research to me is often remembered when I see various novelties. Many brands not really understand the audience, try to be allocated on the shelf in supermarket, but buyers remain very conservative, after all it is about personal hygiene. And Nivea understands the buyer, at all innovations remains moderately conservative and predictable brand.
And now about perfumery composition. It is good. Very womanly. Various white flowers (a lotus, a rose, an orchid) and water notes came back to memory. At dispersion aroma strong, it is even possible to tell powerful. But quickly "settles" on skin, does not hammer perfume, leaving only feeling of freshness. On clothes, by the way, does not remain. But only on skin (and that, the first hours).

Packing
Recently often I meet deodorants sprays which have a possibility of "lock" - to fix a spray opening in an open and closed position. In what the reason, why it?
At first it seemed to me that it in order that accidentally spray was not pressed in a handbag, for example, or in a suitcase. But someone faced it? It is unlikely it is possible. Then I thought about small children – it is made that they did not spray accidentally on themselves if suddenly decide to play with mother's cosmetic "wealth". But you saw modern children? They absolutely cannot decipher a piktogrammka on packing and to understand how the lock opens. Besides, they copy behavior of mother, and for certain will remember that she turns a cover before using a deodorant.

Generally, these reasonings led me up a blind alley a little. All explanations some naive. Then I remembered what happens to deodorants which have no "lock". They everything have a lid! And it is often lost. But existence of a cover gives feelings of a clean product: any mote and any bacterium did not get to a spray opening. For certain this "lock" Nivea decided to help us: first, any more it is not necessary to worry on the lost cover (it is not necessary), and secondly, there are no doubts that dirt, dust and microbes got to the spray. At hairsprays and sprays for laying so far I did not see such locks, - it is possible, this business of the future. But in principle, hair preparations are not sprayed on skin therefore especially you should not worry about it so far.

48 hours
I believe that this deodorant can protect from sweat during this time. But so far I had not to use his two days without shower. By the way, you know the last counter in application of deodorants and antiperspirants? Some time ago there were councils to use a deodorant not in the morning, and for the night. It is considered that work of sweat glands at this time quite strong. Here also advise now to apply for the night and dry shampoos, both deodorants, and pimples medicines … I tried, did not see a special difference. But if you want to estimate this council – can experiment. Perhaps, it will suit someone.It seems to me, protection against sweat very good. I compare to Fa, Rexona, Malizia. Nivea proved very well, it is possible not to worry all day if in the morning to put "Invisible protection". And clothes as it should be!

To be fair, I will note that at each of these deodorants it is possible to find some minuses. For example, alcohol in structure, artificial dyes or parabens …

As a part of Nivea there are no alcohol, dyes, parabens. However, there is a propylene glycol, about it it is specified on packing. Not all love this ingredient. But formulas of deodorants seldom do without it, I found it both at Malizia, and at Fa. My skin did not show any reaction to structure of an antiperspirant of Nive – means, this product suits me, and I advise you to try. Will not bring.
