The Sun Is Our Only Source of Light on Earth.

The sun is both our best friend and our worst enemy, so let us first talk about its many benefits.

• Sunlight promotes the production of vitamin D, which is beneficial for bone calcification. Just a few minutes of moderate sun exposure each day is enough. The sun strengthens bones and is also highly appreciated in cases of osteoporosis.
• Sunlight boosts our mood. It is the light received by our eyes that “boosts” our morale and may help combat seasonal depression. Our sense of well-being is also improved. This stimulating effect acts through serotonin, a neurotransmitter involved in regulating mood and appetite.
• Sunlight helps regulate sleep. Light perceived by the retina is transmitted directly to the brain, which links the information to the pineal gland. At the end of the day, this gland secretes melatonin, a hormone that promotes sleep.
• There may be a connection between hyperactivity in children and lack of light exposure. Studies suggest that children exposed to higher light intensity may be “protected” thanks to improved sleep rhythms.
• The sun may help reduce blood pressure, strengthen the immune system, improve oxygenation, and is also recommended in certain skin conditions.

We are all grateful to the sun for these beneficial effects, but we also know that prolonged exposure can have dangerous, even very dangerous consequences.

Heatstroke is particularly dangerous for infants and elderly people. Excessive exposure causes burns, commonly known as sunburn. The skin becomes red and painful. Later, it peels, signaling the death of millions of cells. The deeper the skin layers affected, the more serious the burn. Repeated sunburns also greatly increase the risk of skin cancer.

Tanning may provide some protection against the sun, but it should not be forgotten that it is actually a response to skin aggression. UVA rays accelerate skin aging whether they come from the sun or tanning lamps. As with sunburn, the fairer the skin, the more sensitive it is. The skin loses its suppleness, becomes dry, and wrinkles appear and deepen.

Skin cancer linked to excessive sun exposure has become a major public health issue, with more than 2 million new cases each year worldwide.

The solution to these problems is moderation in sun exposure. However, it is sometimes difficult when relaxing at the beach, alternating between swimming and resting, or playing beach volleyball with friends. Before realizing it, the shoulders, nose, or face turn red — the skin has suffered a “heat shock.”

We have discussed burns caused by the sun, but other burns can also occur in daily life:

• Burns caused by fire (stove, fireplace, campfire, lighter, matches…)
• Burns caused by boiling water or other hot liquids (oil, paint…)
• Burns caused by steam from a pressure cooker
• Repeated skin friction causing blisters against a hard surface, such as long walks with new shoes that create fluid-filled blisters. Although generally harmless, these painful skin injuries should not become infected.

It is important to know that the skin (including the epidermis and dermis) is the largest organ of the body, with a surface area ranging from 1.5 to 2.2 m². The skin is permeable: if too much of it is burned or damaged, it can no longer properly absorb oxygen from the air and release carbon dioxide through cutaneous respiration. The more extensive the burn, the greater the risk of complications.

The burns mentioned above are generally first-degree burns (affecting only the epidermis) or superficial second-degree burns (affecting the epidermis and part of the dermis). Third-degree burns are far more serious: the skin becomes charred and the epidermis, dermis, and hypodermis are destroyed, often requiring skin grafts.

For all these domestic burns and sunburns (first-degree and superficial second-degree burns), we recommend Cytamphological Oil 503, developed by Jean-Paul Geoffroy.

This product contains a Cytamphological formula (a highly elaborate combination of plant active principles at 0.6%) and 99.4% wheat germ oil known for its soothing, antioxidant, and firming properties.

503 is presented as a solution for sunburn relief. As soon as the sensation of heat appears, apply it as quickly as possible to the affected areas. Blisters generally do not appear the next day.

For household burns, immediately apply 503 to the affected hands or arms. The pain is quickly soothed and a sensation of comfort appears rapidly. The skin soon regains its normal appearance, including in the case of blisters. The results are truly remarkable.

503 contains no colorants, preservatives, or allergens.

503 comes in a 15ml bottle.

503: apply a few drops to the affected area several times per day.

503 is ESSENTIAL at home, in the kitchen or bathroom cabinet, in a hiking backpack, or in your suitcase when traveling on sunny holidays.
