What are the health consequences of using low-quality sunscreen?

Low-quality sunscreens and shampoos may contain harmful chemicals and ingredients of unknown origin, causing numerous problems for hair and scalp, increasing the risk of skin cancer, and heavy metal contamination.

Risk of dermatitis and cancer.

Dr. Ta Quoc Hung, a specialist in Dermatology and Cosmetic Dermatology at the University Medical Center of Ho Chi Minh City, stated that using low-quality shampoos will not effectively clean the scalp and will lead to many side effects such as scalp inflammation, irritation, hair loss, oiliness, and fungal scalp scaling... "As for low-quality sunscreens, their use not only fails to be effective but can also cause sunburn, dermatitis, and prolonged use can lead to heavy metal contamination, hormonal imbalances, and in pregnant women, it can affect the fetus...", Dr. Hung added.

Sharing the same view, a dermatologist at Xuyen A General Hospital (Ho Chi Minh City) stated that using low-quality shampoo can cause chronic inflammation of the scalp, leading to weakened, brittle, and damaged hair. If the shampoo contains many harmful ingredients and a high concentration of detergents, these can be absorbed through the skin, causing irritation and increasing the risk of cancer.

In particular, formaldehyde and parabens, despite many products being advertised as formaldehyde- and paraben-free, can still be present in many shampoos on the market.

Formaldehyde is a chemical compound used as a preservative in some consumer products, including shampoos, to prevent the growth of bacteria, mold, and yeast, thus extending shelf life.

Formaldehyde can cause irritation, allergic dermatitis, and respiratory illnesses. Many studies show that people who are frequently exposed to this substance are at increased risk of leukemia and cancers such as sinus and nasopharyngeal cancer.

Parabens are chemical preservatives that have long been used in beauty products such as shampoos and lotions. Studies show that parabens can be quickly absorbed through the skin and penetrate the body's tissues. This causes allergic contact dermatitis and other problems such as redness, irritation, itching, peeling skin, as well as dryness and damage to hair.

Using low-quality sunscreen can cause many skin problems.

Low-quality sunscreens often fail to effectively protect the skin from UV rays. Conversely, they may contain harmful substances that cause numerous skin and health problems, such as:

Sunburn, tanning, redness, blistering, and vesicles : These are skin damage caused by prolonged exposure to intense sunlight.

Allergic reactions : Some chemical ingredients in low-quality sunscreens, such as oxybenzone, avobenzone, or preservatives, fragrances, and alcohol, can cause itching, rashes, hives, and swelling.

Acne breakouts, clogged pores, or dry, flaky skin : Some chemicals in low-quality sunscreens can clog pores, creating conditions for acne development, or can cause dehydration, leading to dry, tight, and flaky skin.

Premature aging : When UV rays are not blocked, they destroy collagen and elastin, causing wrinkles, sagging, age spots, and freckles, leading to rapid skin aging.

Increased risk of skin cancer : Without a protective layer, the skin is directly affected, leading to serious damage and significantly increasing the risk of skin cancer.

Sunscreen distributed by Doan Di Bang: Cannot provide sun protection.

"Consumers should be cautious when choosing consumer products, seeking reputable sources with clear origins and carefully reading ingredient information. Those with sensitive skin should consult with specialists to choose suitable products or test them on a small area of ​​skin before use. If any unusual symptoms appear, stop using the product and immediately seek medical attention for timely examination and treatment," the doctor advised.
