Mineral Filters Protect Your Skin From The Sun

Solar radiation is a source of well-being and joy : it helps to improve mood and favors the natural production of vitamin D.

On the other hand, it can cause risks to the skin and health if adequate photoprotection is not carried out.

The tan is nothing other than the defense system that has preserved the skin to the harmful effects of sunlight.

The melanin is activated under the action of ultraviolet rays causing hyperpigmentation that we identify with the “tan”.

Skin cancer, premature skin aging and the progressive increase in dermal sensitivity to the sun are changing our habits.

We are increasingly aware of the importance of protecting the skin from solar radiation but also from chemical substances that can be harmful.

Hence, the search for natural alternatives in different facets of life also affects sun protection.

What are mineral filters?

Chemical filters absorb photons from solar radiation, altering their molecular structure.

They are the ones that most sunscreens on the market carry and their use is very common, because they are transparent, easy to apply and do not stain clothing, although they can be absorbed through the skin.

The natural alternative is mineral filters and plant extracts, which ensure a high dermatological tolerance, avoiding the allergic reactions sometimes caused by chemical filters, perfumes, preservatives, dyes and synthetic emulsifiers.

Mineral filters are also known as “physical filters”. They are composed of minerals that reflect solar radiation forming an opaque barrier and acting as if they were small mirrors.

Its effect is immediate, so it is not necessary to apply them for a while before sunbathing, and they protect against UVA and UVB rays, although they have the disadvantage that when applied they usually leave a whitish layer on the skin.

The most common mineral filters are titanium dioxide, magnesium dioxide, zinc oxide, calcium carbonate and talc.

Other natural filters come from plant substances or seed oils that filter part of the radiation while providing regenerative and restructuring substances.

How to use them properly?

Applying the product evenly and abundantly, repeating the application during exposure, gradually sunbathing and avoiding the sunniest hours are essential precautions.

You have to be cautious in spaces that reflect solar rays, such as sand, water or snow and be wary of cloudy days, since ultraviolet rays pass through the clouds.

It is advisable to wear approved sunglasses and protect the body and head with some clothing, especially children and people with very light skin.

When choosing sunscreen, the ideal is to choose a broad spectrum filter, which protects from both UVA and UVB rays, and an adequate protection factor depending on skin tone, place and time of exposure .

Children are the most vulnerable, as they have very thin skin and an underdeveloped skin protection system. Like people with light skin and eyes, they must use higher protection.

After sun exposure it is important to calm and hydrate the skin. Aloe vera gel is ideal for after the sun .

In the plant world there are numerous oils, waxes and flower essences with a repairing, moisturizing and antioxidant effect, such as avocado or rosehip oils, both regenerating.

It can also be prevented with shea butter, which prevents dehydration and also improves damaged hair.

Finally, for those who want a darker tone without being exposed to the sun, there are easy-to-apply, cooked earths with a very natural tanning effect.

Protect yourself from the sun from within

A diet rich in fresh fruits and vegetables and essential fatty acids helps to hydrate the skin and strengthen its defenses.

In recent years, oral cosmetics have developed a lot , based on food supplements that help take care of the skin from within.

Some of them promote tanning and neutralize the oxidative processes of solar radiation.

They are usually made from beta-carotene, the antioxidant pigment in orange fruits and vegetables, such as carrots, pumpkins, or apricots, although they may contain other carotenoids and vitamins C and E.

They cannot be used as a substitute for sunscreen but they contribute to photoprotection and increase antioxidant levels in the skin and blood.

It is recommended to start taking them at least fifteen days before sunbathing.
