E' primavera! mani e piedi in primo piano



It’s springtime! Let’s take care of our hands and feet

Dr. Giulia Leoni

Have you ever thought about how hands are important in our life: tool to substitute a missing word in a conversation, give love with a caress, carry out our daily activities. 

Our hands powerfully communicate: they are our business card. They barely lie to us about age and they reveal evidently age’s signs, when detracted

How many times a day do we expose our hands to repeated trauma?

Have you ever thought how many times our hands are subjected to continuous injuries? Let’s think about the simple gesture of washing hands with ice-cold water, changing suddenly from warm to frozen places during winter or using harsh detergents in home cleaning activities. After such a harsh treatment, our hand skin become certainly red and dry. 

The first defense barrier of skin is made of hydrolipidic film, which naturally protects our hands from environmental changes. However this buckler  has a limited resistance. Indeed, our hands, than other body areas, are more fragile due to the limited amount of sebaceous glands, that make them more subjected to dryness. Moreover, they are always exposed to sunlight, also during winter.

You should everyday protect hands from external injuries, re-equilibrating natural hydrolipidic protective film with the aid of a suitable nourishing and moisturizing cream.

Come proteggere le mani e i piedi?

Born in the laboratories, the hand cream GlovÉ is a complete wellness treatment that combine a protective action with a moisturizing and elasticizing action. 

Precious elements, such as natural ceramides  and  vitamin E along with pure essential oils and  distilled water rich of oligoelements, give elasticity and hydration to the skin tackling redden skin and irritations. With a silky texture and  a gentle non-greasy touch, the hand cream represents an invisible glove that naturally protect hands from external injuries, such as cold, detergent and chemical compounds.

Feet deserve equally our attention especially during springtime when they usually are exhibited. Even if they are in the spotlights during summertime, they should not be distracted during the rest of the year. In foot reflexology, body shape is compared to a tree: roots correspond to feet, trunk is our spinal column whereas leaves are represented by face. According to this methodology Feet maintain the microcosm of human being so that they should be kept stable and healthy. 

If they are neat and beautiful, they could be appealing, especially when uncovered. In spite of not being so prominent, feet should paid a special attention too. 

C.R.P. foot cream is  specifically designed to give relief to tired feet and attenuate problems related to strong dryness, such as hard skin and calluses. Talc, with the absorbing action, reduces abundant sweat whereas Tea Tree oil and the antiseptic essential oils help in protecting feet from mycosis and from excessive bacterial proliferation caused by closes shoes.

Beauty wakes up during springtime! 

Let’s take time to regenerate and shine our hands and feet with dedicated specific treatments.

Cyclooxygenase, lipoxygenase and the inflammatory process

Cyclooxygenase and lipooxygenase are the two families of enzymes that are commonly involved in the inflammatory process, through a complex of reactions which is called arachidonic acid cascade. This complex of reactions develops as follows: a first enzyme, a phospholipase cleaves the phospholipids of biological membranes, releasing arachidonic acid, a polyunsaturated fatty acid with 20 carbon atoms (eicosa-5Z,8Z,11Z,14Z-tetraenoic acid ; C20:4; ω-6). The arachidonic acid is then transformed by two parallel enzymatic pathways, that is, by two families of enzymes: the cyclooxygenase which transforms it into prostaglandins and thromboxanes and the lipooxygenase which transforms it into hydroperoxides which in turn transform into leukotrienes .
There are two cyclooxygenase isoforms indicated with type 1 and type 2, briefly COX-1 and COX-2. COX-1 is the enzyme present in most cells (except red blood cells), and is constitutive, that is, it is always present. COX-2 is an inducible cyclooxygenase isoform: it is constitutively present in some organs such as brain, liver, kidney, stomach, heart and vascular system, while it can be induced (i.e. developed if necessary) following inflammatory stimuli on the skin, white blood cells and muscles.
There are various types of lipooxygenase that lead to different products, the most important in the inflammatory process is 5-lipooxygenase, 5-LOX.

Prostaglandins, Thromboxanes, and Leukotrienes

Prostaglandins, Thromboxanes, and Leukotrienes are chemical messengers or mediators, that is, molecules that bring a message to specific cells and activate or deactivate metabolic responses in these cells. They, therefore, have a function similar to hormones, only that, unlike what hormones do, the chemical message is carried only at a short distance, that is, only to the cells that are in the vicinity of the place where the mediators were produced. There are different prostaglandins, different thromboxanes and different leukotrienes that carry specific messages. In many cases these act as mediators of the inflammatory process , therefore they trigger all the events that are involved in inflammation:
– vasodilation with consequent blood supply (redness),
– increased capillary permeability with consequent fluid exudation (swelling or edema),
– stimulation of nociceptive nerve signals (pain),
– on-site recall of immune system cells that attack a possible invader (chemotactic action)
– activation of the biosynthesis of fibrous tissue to strengthen or repair the affected part (even if there is no need)
– generations of free radicals that can chemically destroy an invader (but also damage our tissues, i.e. they just “shoot in the middle”).
Prostaglandins and thromboxanes, however, also play important physiological roles in normal conditions, i.e. in the absence of inflammation. For example, they regulate the secretion of mucus that protects the walls of the stomach, they regulate the biosynthesis of cartilages and synovial fluid in the joints, they regulate vasodilation, hence the correct flow of blood in the various local districts, and more.


Triglycerides are the main components of most oils and fats. These are heavy, non-volatile and little polar molecules, insoluble in water, made up of glycerol (or glycerin) esterified with three molecules of fatty acids: therefore, it is a tri-ester of glycerin, from which the name derives. Each fatty acid contains 8 to 22 carbon atoms (commonly 16 to 18) and can be saturated, mono-unsaturated or poly-unsaturated. The size of the fatty acids and their saturation determines the physical and sensorial properties of the triglycerides, which can appear as oils (liquids at room temperature) or fats (solid or semi-solid) and can have greater or less greasiness and smoothness on the skin. Unsaturated triglycerides or with shorter fatty acids are more fluid and have greater flowability.

Fatty acids (saturated, mono-unsaturated and poly-unsaturated)

The name fatty acids is commonly used to indicate those organic acids that are found in the composition of lipids, that is, in animal and vegetable oils and fats, both in the free form and in the form of esters with glycerol (e.g. in triglycerides), or they are esterified with “fatty” alcohols, that is, long chain alcohols, to form waxes. Fatty acids are carboxylic acids (formula R-COOH) which have a long carbon chain (R), unlike common organic acids such as acetic acid and propionic acid, which have 2 or 3 carbon atoms in total, respectively. Fatty acids are defined as saturatedif they do not have double carbon-carbon bonds, (called “unsaturations”), they are defined mono-unsaturated if they have only one, they are defined mono-unsaturatedpoly-unsaturated if they have two or more double bonds (see figure). The term omega-3 (ω-3) or omega-6 (ω-3), refers to the position of the first double bond starting from the bottom of the chain of carbon atoms: if the first double bond is encountered after 3 carbon atoms the fatty acid is classified as omega-3 , if after six carbon atoms omega-6 , as shown in the figure. The most common saturated fatty acids are palmitic acid (16 carbon atoms and no double bond, C16: 0) and stearic acid (18 carbon atoms, 18: 0), the most common mono-unsaturated is the oleic acid, typical of olive oil (18 carbon atoms and 1 double bond in position 9, C18: 1; ω-9), while the most common poly-unsaturated are linoleic acid and linolenic acid, progenitors respectively omega-6 and omega-3 (see figure).

Terpenes and terpenoids

Terpenes or terpenoids are a large family of natural molecules, typically containing 10 to 30 carbon atoms, which are biosynthesized from a common “brick”, isopentenyl pyrophosphate (IPP), containing 5 carbon atoms (see figure). The discovery that the repetitive brick consists of 5 carbon atoms is relatively recent, while it was once assumed that the entire family was created by repeating a brick of 10 carbon atoms, which was called “terpene”. Therefore, the molecules with 10 carbon atoms (such as limonene, see figure) were called mono-terpenes, i.e. composed of a single brick, diterpenes those with 20 carbon atoms (e.g. the cafestol that gives the aroma to the coffee), triterpenes those with 30 carbon atoms (e.g. beta-carotene). Since molecules made from 15 carbon atoms were also found (such as bisabolol), it was thought they contained a terpene and a half, and were called sesquiterpenes (from the Latin semis = half + atque = and). Today it is known that the repetitive unit is composed of 5 carbon atoms, therefore it is easy to understand how mono-terpenes contain two (see figure), sesquiterpenes three, diterpenes four, triterpenes six.
