Physical or Chemical: Which filter in sunscreen is better?

Although the weather leaves a lot, the holiday season, strawberry smoothies and just in the corner of the sun. This means that it is time to add the main cosmetic drug to your beauty rut-sun screen. You already know the best SPFs and you understand how to wash them. And today we will analyze which filter in sun cream is better.

Ultraviolet radiation types

To find the perfect product, you must first find out exactly what we defend. There are only three types of ultraviolet radiation:

UVC rays are the most dangerous for people, but we are protected by a ozone atmospheric layer, so UVC rays do not reach the epidermis and do not burn the skin.

UVB rays can leave epidermis penetrations and burns. The most active from spring to autumn.

Over the year, UVA rays active, penetrate the dermis. They cause premature aging, pigmentation, wrinkles and oncology.

The main purpose of the cream is to protect against UVB and UVA rays.

Sign

You should also pay attention to the labeling of the product:

-SPF (sun protection factor) is a protection factor against UVB rays. SPF is suitable for daily use. Different levels of density when the product is given. So, SPF15, 15, SPF30 – Missing 1 beam

-Pa (UVA’s protection class) -Uva protects against Ra Ra Raves. It is especially suitable for people with sensitive and bright skin. In addition to PA marking, PA ++++ is placed in the most powerful protection.

-PPD (permanent pigment darkening) -Also protects against UVA rays, but fights against the constant darkening of the skin pigment. The density is indicated by numbers. For example, PPD8 means that 8 % of the rays will be blocked.

-Gu-Gug-Damascus waterproof sunscreen.

– Hev – Protection against blue radiation.

– IRA – protection against infrared radiation (energy type where objects are heated without heating).

Sunscreen Filters

The composition contains sunscreen filters. They are those who absorb or reflect radiation and protect the skin. There are two types of filters in total:

Chemical (organic). They absorb ultraviolet and convert it into thermal energy. Chemical filters need time to absorb the skin, so it is better to apply the cream just before the output. In order to maintain photo stability, the cream must be updated regularly (the ability of molecules to protect the stability of any solar radiation).

Physical (mineral). They are not absorbed into the skin, but they form a mirror covering that is broken and pushing ultraviolet.

Mixed. Now many brands choose a mixed option. That is, the cream contains both chemical and physical filters.

Advantages and disadvantages

Chemical

Advantages. They do not leave the white lines on their face, but they need time to absorb the skin, so it is better to apply it just before the output. To maintain photo stability, you need to update the cream regularly.

Flaws. Chemical filters contain non -secure components for the skin. For example, Zixonsate and Octinovsate. Choose the latest generation chemical filters to find a product that will not harm. Compositions include Tinorb, Mexol, Juvulov.

Physically

Advantages. Physical filters are considered safest and most hypoallergenic. The main advantages are to reflect the rays from the surface of the skin.

Flaws. Due to intense texture, mineral filter creams can leave white lines on their face. They contain zinc oxide and titanium dioxide connected by polymers. They were recognized safely.

Mixed

Advantages. The cream works much longer. Chemicals are gradually absorbed into the skin immediately after and over time.

Flaws. Mixed filters can more frequent skin irritation. Therefore, test the product before applying to the face.

When choosing a sunscreen, take into account all pros and cons and find a right remedy for you.
