SPF

SPF, An indicator describing the level of protection against erythema-causing UVB radiation when the product is used correctly.

What does the term "SPF" mean?

An indicator describing the level of protection against erythema-causing UVB radiation when the product is used correctly. In cosmetology and trichology, the meaning of this term always depends on the context: the location of occurrence, symptoms, duration of the problem, products used, and individual tolerance.

What is its practical significance?

Understanding the concept helps to better comprehend cosmetic descriptions, specialist recommendations, and the mechanisms occurring in the skin or hair. However, it does not mean that self-diagnosis of a single element is sufficient to select a therapy.

What to pay attention to?

It is not worth evaluating a product, ingredient, or procedure solely based on the popularity of the term. Formulation, concentration, method of use, contraindications, and skin condition are important. Introduce changes one by one and observe the reaction.

When is a consultation needed?

If the problem is severe, recurs, causes pain, intense itching, inflammation, sudden hair loss, or a significant change in skin appearance, consult a dermatologist. A cosmetologist or trichologist can support care and refer you to the appropriate specialist.
