Understanding the effects of the sun on the skin

The effects of the sun on the skin

Solar radiation , essential for life, has ambivalent effects on our skin. On the benefits side, moderate exposure to UVB rays naturally stimulates the production of vitamin D , essential for many of the body's functions, including the proper functioning of the immune system, bone strength , and overall body balance. The sun also has a positive influence on mood, regulating sleep-wake cycles and promoting the secretion of serotonin.

But the sun can also become harmful in case of excessive exposure or without adequate protection. Solar radiation is composed of different types of ultraviolet (UV) rays. UVA rays, which penetrate deep into the dermis, contribute to premature skin aging . UVB rays, on the other hand, act on the surface and are responsible for sunburn : the famous sunburn .

Prolonged exposure, without sunscreen or protective textiles, weakens the skin barrier , leads to dehydration of the skin and triggers an inflammatory reaction : redness, heating, pain, and even the appearance of blisters.

Sunburn: inflammation and damage to the skin layers

A sunburn is a first-degree burn . It primarily affects the epidermis. However, in cases of excessive exposure, the burn can be deeper (superficial second-degree) with the formation of blisters. In all cases, the skin is inflamed, sensitized, and requires gentle, soothing, and regenerative care.

The Most Effective Essential Oils for Soothing Sunburn

Lavender Aspic Essential Oil: the ultimate anti-inflammatory sunburn remedy

The undisputed queen of natural emergency care, Lavender Aspic Essential Oil (Lavandula latifolia spica) has powerful anti-inflammatory and healing properties. It is particularly indicated for relieving sunburn, superficial burns or insect bites . Its calming effect is almost immediate, and it limits the risk of superinfection.

Fine Lavender Essential Oil: soothing and well tolerated

Gentler, Fine Lavender Essential Oil (Lavandula angustifolia) also works on minor burns . It provides rapid relief while promoting cell regeneration. Very well tolerated, it can be used on children or sensitive skin, always diluted.

Rose Geranium Essential Oil: restorative and skin tonic

Rose Geranium Essential Oil (Pelargonium graveolens) effectively complements the action of lavender. It helps accelerate skin repair and prevent post-exposure peeling .

Lemon Eucalyptus Essential Oil: soothing and anti-inflammatory

How to use an essential oil against sunburn?

Cutaneous application: dilution, dosage and frequency

Which vegetable oil should I use to soothe my skin?

Precautions for pregnant women and those with sensitive skin

Essential Oils to Avoid During Pregnancy

Most essential oils are not recommended during the first trimester of pregnancy. Some, such as Spike Lavender (containing camphor) or Lemon Eucalyptus, should be avoided by pregnant and breastfeeding women. Generally speaking, it is best to avoid using any essential oil without medical advice during this period.

Safe after-sun products for pregnant women

In case of sunburn, pregnant women can opt for 100% gentle and natural solutions:

• Vegetable Oils applied with a light massage ;
• True Lavender or Roman Chamomile Hydrosols, to be sprayed on heated skin for an immediate sensation of freshness .

These risk-free treatments offer immediate relief while respecting the specificities of this sensitive period.

Possible reactions and mistakes to avoid

Some Essential Oils are photosensitizing (such as Citrus Essences): they should never be applied during the day. Also avoid pure Essential Oils, excessive dosages, or applications on damaged skin (blisters, extensive burns). If in doubt, always seek the advice of a healthcare professional.

Caution: St. John's Wort Vegetable Oil is a valuable ally for skin well-being , especially after prolonged sun exposure. Thanks to its soothing and restorative properties, it can be used on overheated, sensitive skin, etc. It is particularly useful as an after-sun treatment, thanks to its calming action on weakened areas. However, it is photosensitizing : if exposed to the sun after application, it can cause skin reactions. It is therefore essential to use it only in the evening , ensuring that a minimum of 8 hours have passed before any sun exposure .

Natural alternatives to soothe sunburn

Aloe vera gel: natural after-sun soothing

Aloe vera gel is one of the skin's best allies in summer . It intensely moisturizes , helps calm skin overheating and promotes tissue repair . Applied in a thin layer, it penetrates quickly without leaving a greasy film and can be used in synergy with hydrosols or vegetable oils.

Hydrolats: immediate freshness and comfort

Hydrosols are aqueous extracts obtained during the distillation of plants. True Lavender or Chamomile Hydrosol are particularly recommended for soothing sunburn .

As for Peppermint Hydrosol, it will bring freshness to the skin.

Sprayed several times a day, they provide an immediate feeling of freshness , without any risk for pregnant women or young children.

When to combine Essential Oils and natural care?

You can absolutely alternate or combine different natural treatments for greater effectiveness:

• A hydrosol spray after exposure;
• Then a treatment based on vegetable oil and essential oils in the evening;
• And aloe vera gel if needed.

This global approach promotes rapid recovery of the skin while respecting its sensitivity .

Prevention: Avoid sunburn naturally

Good reflexes for responsible exhibition

Summer vacations are often an opportunity to slow down, reconnect with yourself and savor simple pleasures: a nap in the shade, reading on the beach, a walk in the mountains... But beneath this atmosphere of relaxation and well-being, the sun can quickly become a false friend for the skin if we don't take a few precautions.

To benefit from its advantages – notably the synthesis of vitamin D , which is valuable for our immunity and our morale while avoiding unpleasant effects such as sunburn – certain actions must become second nature.

• Avoid exposure between 12 p.m. and 4 p.m. , when UV rays are at their strongest. This time slot can be used to rest in the shade, have a leisurely lunch, or explore a city away from direct sunlight.

• Choose protective clothing : lightweight long-sleeved t-shirts, loose-fitting pants, wide-brimmed hats, and certified sunglasses. A fabric barrier remains one of the most effective forms of protection;
• Apply a sunscreen suitable for your skin type , with sufficient protection, even in the shade or on cloudy days. Remember to reapply every two hours, and after swimming or heavy perspiring;
• Hydrate regularly : In summer, water loss is greater. Proper hydration helps maintain skin elasticity and contributes to its natural regeneration after sun exposure.

Which sunscreen should I choose in addition to after-sun care?

Choose mineral sunscreens made with zinc oxide or titanium dioxide without controversial chemical filters. These natural filters act by forming a physical barrier against UV rays, without penetrating the epidermis. At the end of the day, remember to cleanse your skin thoroughly and apply a moisturizing or soothing treatment , such as Calendula Vegetable Oil or Aloe Vera Gel, to strengthen your skin barrier.

Sunburn , although often benign , requires gentle and rapid treatment to avoid complications and preserve the health of the skin . Thanks to certain Essential Oils such as Lavender Aspic , True Lavender or Rose Geranium Essential Oil, it is possible to soothe sunburn naturally while accelerating tissue repair . Combined with complementary treatments such as Calendula Vegetable Oil , Aloe vera or True Lavender and Chamomile Hydrosols , they become valuable allies in the summer .

But the best protection remains prevention : exposure in moderation , hydration , and adopting the right actions before, during and after the sun.
