  • Harmful Substances in Foundation

Foundations are widely used cosmetic products. However, some ingredients in many foundations can be potentially harmful.



Parabens are chemicals used as preservatives in many cosmetic products. However, some research suggests that parabens may have endocrine-disrupting features and disrupt hormone balance. Also, some people may have allergic reactions to parabens.

Some studies suggest that parabens in cosmetic products may be associated with breast cancer and other types of cancer. However


, findings on this subject are still controversial and there is no definitive evidence. More research is needed to assess potential risks.

Parabens can have estrogen-like effects in the body. Some research suggests that parabens may affect the endocrine system, causing hormone imbalance and hormonal disorders. This can be a harmful chemical, especially in cases of long-term and high exposure.


Cosmetic and skin care products such as foundations, lotions, moisturizers, nail polishes and hair dyes contain parabens.

Parabens can cause skin irritation, rash, itching, and allergic reactions in some people. Those with sensitive skin may be especially sensitive to products containing paraben.

Parabens can cause environmental impacts when released into wastewater systems and the environment. The release and accumulation of these substances into the environment can lead to potentially harmful effects on ecosystems.


Phthalates are chemicals used to increase the elasticity of foundations. However, some studies show that phthalates may have adverse effects on the reproductive system. It is stated that these substances have potential risks, especially during pregnancy and the development of children.

The endocrine system is important for the secretion of hormones and regulation of biological processes in the body. Phthalates may have adverse effects on the endocrine system. Some research indicates that phthalates may specifically disrupt hormone imbalance and the normal function of hormone receptors. This can cause negative effects on many systems, from the reproductive system to thyroid functions.

Phthalates can negatively affect sperm quality and reproductive functions in men. Some studies show decreased sperm count, impaired sperm motility, and changes in hormone levels in men exposed to high levels of phthalates.

Exposure to phthalates during pregnancy or infancy may affect the normal development of children. Some studies suggest that babies exposed to phthalates are associated with health problems such as low birth weight, increased risk of premature birth, and childhood obesity.

Some people may have allergic reactions to phthalates. Especially those with sensitive skin should be careful when using cosmetic products containing phthalates.

Mineral Oils

Mineral oils are a group of ingredients used as moisturizers in some foundations. However, mineral oils are not easily absorbed by the skin and can clog pores. This may cause some skin problems. Clogging pores is one of these problems. Mineral oils can prevent the skin from breathing naturally and clog pores. This can lead to blackheads, acne and other skin problems. Especially those with oily skin should avoid products containing mineral oil or use them with caution. Another skin problem caused by mineral oils is skin irritation. Those with sensitive skin may experience redness, itching, dryness and other allergic reactions when they use products containing mineral oil.

While mineral oils give the skin a feeling of moisture, they do not actually penetrate deeply into the skin. Therefore, they do not contribute to real moisturizing and nutrition of the skin.

Perfumes and Synthetic Fragrances

Many foundations contain perfume and synthetic scents. However, these substances can cause skin irritation and allergic reactions. These effects may be more pronounced, especially in people with sensitive skin.

Perfume and synthetic fragrances in foundations can cause skin reactions in some people. Especially those with sensitive skin may be more sensitive to these scents. Allergic reactions such as skin redness, itching, dryness and rashes may occur.

Some synthetic fragrances can affect the endocrine system and lead to hormone imbalance. When the endocrine system is disrupted, reproductive functions, immune system and other biological activities may be affected.

Perfume and synthetic fragrances in foundations can evaporate and be inhaled when the product is applied. This can lead to breathing problems such as headaches, nasal congestion, sneezing, and breathing difficulties in some people.

The release of chemicals used in the production of synthetic fragrances into the environment can also cause environmental impacts. The release of these chemicals into water sources and soils can negatively affect ecosystems and cause environmental pollution.

Bismuth Oxychloride

Bismuth oxychloride in some foundations is used to provide shine to the skin. Bismuth Oxychloride may cause allergic reactions in some people. After skin contact, symptoms such as redness, blistering, rashes and even itching may be observed. Therefore, individuals with allergies are advised to avoid using products containing Bismuth Oxychloride.

Bismuth Oxychloride in powder form may cause irritation to the respiratory tract when inhaled. Respiratory problems may occur, especially if dust is released into the air during or after the product is applied. This can be especially problematic for those with sensitive lungs.

Bismuth Oxychloride may cause eye irritation when in contact with the eyes. Users should be careful when applying the product around the eyes and avoid eye contact. Symptoms such as redness, watering and irritation may occur as a result of eye contact.

Bismuth Oxychloride in powder form may cause digestive system problems if swallowed. It may be dangerous, especially for children, and precautions should be taken against accidental ingestion.

Sensitivity to some of these harmful substances in foundations may vary and not everyone may be affected to the same degree. It's also important to carefully read products' ingredient lists to identify potential harmful ingredients and find safer options for your skin.
