For sure you have been asking yourself if you have to nourish your skin in any other way than usual. While being at the beach skin needs more care because we are exposed to the sun that can burn us and sea salt drains the skin. So how to nourish the skin at sea? How to act in case of sunburns? How to nourish the skin to maintain the tan we have?
How to act in the case of sunburns?
Today, we are already aware of the harmful effects of sunbathing, but the sunburn can happen. Either this is because of the insufficient amount of sunscreen or excessive sunbathing. Burn is an acute skin inflammatory reaction that usually occurs 1-24 hours after sunbathing. The burn depends on the intensity and the wavelength of light. Erythema may occur, which may be accompanied by pain, swelling or even blisters. Of course, the best way is to prevent all this with the appropriate UVA and UVB protective sunscreens.
Not only does exposure to the sun lead to faster aging (photoaging), it can also cause the formation of lentigues, teleangiectasia (spider veins), skin cancer, etc., if we are exposed to the sun without protection.
We can cure sunburns with anti-inflammatory extracts!
In a case of sunburns, we shower with lukewarm or cold water and gentle cleansing agents. After showering, we apply lotions or creams like aftersuns. In case we are burned, cosmetic products should contain the following extracts that soothe the skin.
Chamomile (bisabolol, hamazulen)
anti-inflammatory, wound healing, soothe the skin
adstringent, antimicrobial, anti-inflammatory, antioxidant
antimicrobial, antioxidant, soothes the skin, against itching
anti-inflammatory, wound healing, antiseptic
Due to the content of terpenoids, it acts anti-inflammatory and antimicrobial. It also acts as an antioxidant and protects us from reactive oxygen radicals. It helps to restore the skin barrier and acts regeneratively.
Aloe vera against erythema
The study tested 97.5% aloe vera gel and 1% hydrocortisone in the cream, and 0.25% predicarbate in the cream, both of which are corticosteroids. The effect of natural extracts is delayed. Corticosteroids reduced the erythema after 24 hours, while the gel of aloe vera reduced the erythema only after 48 hours. Although it seems that the percentage of aloe vera gel is high, it did not show any hypersensitive reactions to the testee. So, the aloe vera gel reduces inflammation, but it is not necessary that the gel could be used for chronic inflammatory diseases. It can be used as an additional care, especially in after-sun products, instead of gels / creams containing hydrocortisone.
Usually, oils rich in omega-3 and / or omega-6 are commonly used to treat sunburns, as they work regenerative and anti-inflammatory. We can also use the right antioxidants that prevent the harmful effect of ROS on our DNA. Some studies have shown that vitamin D also helps to relieve the burns produced in the sun.
Well, the other option is to succeed in getting a healthy tan, because the sun does not always burn us to red. We want to keep the tan as long as possible. One option for maintaining a tan are self-tanning products, where the difference in colour is noticeable, but is washed within 1 week.
How to prolong the permanence of tanned skin?
Carrot oil, which was present in the formulations at concentrations of 2, 4 and 6%, has been shown to have SPF factor. The measured SPF values ranged between 4 and 7. This, of course, is not sufficient for proper SPF protection. Carrot oil also works antioxidant and rejuvenating, and at the same time it nourishes the skin properly. It is used as an oil that helps to extend the intensity of the tan. It usually leaves traces on clothes, as the right carrot oil has an orange colour, which does not disappear in the formulation, even if it is present only in 3%.
It has an SPF of about 3, which is not enough to protect us from sun rays, but it still works photoprotectively. At the same time, it works antioxidant and regenerative, as it contains phytosterols and vitamin E. It helps us preserve the tan that we already have.
How to take care of the hair?
We are sure that you have already noticed how our hair colour, whether natural or dyed, fades away while we are at the seaside. People with darker hair struggle with melanin photoxidation, and others with lighter hair with degradation of amino acids in keratin, which is the main structural protein in the hair. Darker hair is somehow better protected against fading than lighter shades.
UVA rays are mainly responsible for the loss of colour in dyed hair, as they penetrate all the way to the cortex where melanin and colour pigments are located. UVB rays are blamed for the fading of the natural hair colour as they percolate into all layers of hair.
Keratin is via cysteine converted into cysteic acid in the final phase. This, however, reduces the resistance of the hair and its elasticity. Therefore, the hair is drier, less shiny, and more difficult to brush through.
Hair cuticle which is the exterior layer is most exposed. Melanin is located in the cortex and is not capable of protecting the cuticle against UV radiation. Radiation destroys proteins and lipids in the cuticle. Hair cuticle opens and the hair loses their softness. In UV radiation, ROS also develops and further destroys the hair.
Are cosmetics with UV filters the solution for hair care?
Until now, there was no excessive enquiry for such products on our market. But there are shampoos and balms with UV filters. In fact, an entire hair care line with UV filters. In hair cosmetics the same UV filters can be used as in sunscreens, but there are also quaternary and polysilicones that exhibits UV protection for hair, but not for the skin. Of course, there are natural oils and extracts that also help protect your hair from UV radiation.
UVA is mostly promoting the formation of ROS, while UVB destroys pigment named melanin (destroying it or bleaching it), and for changing mechanical abilities, as it breaks bonds in our hair (cysteine present in keratin), which makes our hair fragile.
How to groom the face?
At sea, you do not usually need ” heavy care”. For most skin types, the use of rich and nourishing creams and oils in summer is simply too much. Overly enriched care can lead to the formation of clogged pores and pimples. Therefore, it is better to reach for moisturizing formulas. In addition to daily sun cream, it is also recommended to use serums with antioxidants, which will additionally support the function of the sun cream.
