What does SPF cream protect against?

Thanks to the SPF content (chemical and physical UV filters), sunscreen helps prevent the negative effects of ultraviolet radiation on the skin. When such rays affect the epidermis for a long time and in large amounts, they can lead to a number of consequences:


- erythema (skin redness);

- alteration (changes in the structure) of cells;

- hyperpigmentation of the skin and the development of melanoma (skin cancer);

- destruction of epidermal cells;

- appearance of wrinkles and photoaging of the skin;

- oncogenesis (development of tumors).

To avoid the side effects of solar radiation, it is necessary to use sunscreens that protect against harmful rays and have a positive effect on the skin.


What benefits does sunscreen provide?

Sunscreen with SPF reflects and scatters ultraviolet rays (A and B range) that reach the skin, allowing you to tan safely. The positive effects of sunscreen cosmetics include:


Prevention of redness, burns, and pigmentation spots with SPF cream.

Moisturizing and nourishing the skin thanks to natural components in the sunscreen formula, such as oil or extract of aloe, avocado, and peach.

Prevention of photoaging. Regular exposure of the epidermis to ultraviolet rays leads to changes in the structure of cells (they contain less cellular fluid and lose elasticity). Sunscreen protects the skin from sunlight and helps prevent photoaging.


Why can sunscreen be dangerous?

The reason for the harm from some SPF creams lies in their composition and improper use. Namely:


Some sunscreens contain potentially harmful UV filters (avobenzone, sulisobenzone, oxybenzone), which may cause different types of dermatitis, endocrine disorders, and may provoke carcinogenesis (the initiation and development of tumors). Dermatologists do not recommend including these components in cosmetic products, but some manufacturers still use them.

If sunscreen is not washed off for a long time, it may clog pores. The homeostasis (self-regulation) of skin cells is disrupted, which can lead to cell damage.

Sunscreen works for 2–3 hours, after which it should be reapplied. If you stay in the sun for more than 3 hours and do not apply the cream again, there is a risk of burns and pigmentation spots.

With proper use of a high-quality SPF sunscreen, you can tan safely while avoiding negative health consequences!
