Q & A

What is the main focus of the cosmetology course the speaker took?

The course focused on 'non-technical cosmetology,' which deals with understanding the chemistry and practical aspects of beauty products, with an emphasis on their formulation and safety.

What did the speaker learn about the face makeup base and why it is important?

The speaker learned that a good makeup base needs to contain propylene glycol to prevent the pigments from separating in the packaging. This ensures the product remains evenly mixed and effective.

Why is it important to understand the pH levels of different parts of the body?

The pH level varies across different parts of the body, such as the scalp. Maintaining a neutral pH for the scalp helps keep it healthy, and understanding pH levels allows for better skin and hair care practices.

What did the speaker say about the use of sodium chloride in hair products?

Sodium chloride, commonly used in hair products, helps to thicken formulas. It doesn't necessarily harm hair, but products without it may use other more expensive ingredients to achieve a similar effect.

How are dyes and pigments different in cosmetic products?

Dyes are soluble and can be treated to mix well in formulas, while pigments are insoluble and often used in makeup, such as foundation, for their ability to provide color without dissolving.

What is the significance of natural beauty products, according to the speaker?

While natural products are marketed as more sustainable and safer, the speaker emphasizes that they may not always be better. For example, producing essential oils can be resource-intensive, and natural products can vary in quality.

What does ANVISA do to regulate cosmetic products in Brazil?

ANVISA (National Health Surveillance Agency) is responsible for ensuring cosmetic products meet safety standards. It regulates ingredients, ensures products are free from harmful substances, and conducts constant reviews of approved and prohibited substances.

What did the speaker mention about parabens in cosmetics?

The speaker discusses how parabens, once popular as preservatives, have been controversially linked to health concerns. Despite this, there is no conclusive scientific proof that parabens are harmful, but their use has decreased in favor of more expensive alternatives.

What is the difference between irritation and allergy when using cosmetic products?

Irritation occurs when a product causes discomfort or redness, but it stops once the product is discontinued. An allergy, on the other hand, causes a more severe, ongoing reaction that requires medical attention.

How can consumers ensure that the beauty products they use are safe?

Consumers should look for products regulated by authorities like ANVISA, avoid relying solely on internet claims, and consult professionals like dermatologists or chemists for accurate information on the safety and efficacy of beauty products.
