In the case of fragrances, it’s particularly important to protect the molecules that give them their properties and qualities. The key ingredients that contribute to the olfactory signature and fragrance are all impacted and easily degraded by UV rays. Yet they are the most precious part of a fragrance.
If these molecules are broken, or their structure altered, their scent disappears and the perfume rapidly loses its intensity.
What’s more, a perfume is never made up of a single fragrant molecule. It is the result of a subtle balance carefully defined by a talented nose between several fragrances derived from different ingredients. As the impact of UV light is not exactly the same on different molecules, the balance is lost, and the fragrance of the perfume is altered. At best, it becomes less pleasant; at worst, it gives a sensation of sourness.
In both cases – loss of intensity and modification of the olfactory signature – the perfume whose components have been exposed to UV rays will have a very short lifespan, and customers will not be satisfied.

The impact of UV on a fragrance’s ingredients is not limited to the olfactory signature, even though this is of prime importance. Perfume is a precious, luxury product, and its appearance must reflect this. Presented like a jewel, the perfume will have the color of jewels, and its glass or crystal case will make it even more attractive, with its shapes, reflections and transparency.
The appearance of the perfume, its color and its bottle, are therefore the objects of meticulous reflection and creation by perfumers. In this context, UV exposure represents an additional risk. The ingredients that give the juice its color are also fragile. Without protection, the intensity of the perfume’s color diminishes very quickly, in just a few days, as the UV rays break down the colored molecules. The work that was intended to make the fragrance more desirable is irretrievably lost.

The ingredients in cosmetic formulas, fundamental to the efficacy of creams and serums, are also subject to degradation by UV radiation.
Thanks to U^vltimate varnishes, the effect of a cosmetic will remain constant throughout the product’s useful life.
This is an important factor in customer loyalty. If the effect of a cream seems reduced when you reach the end of a jar, you’ll be tempted to try another formula.
