According to the Centers for Disease Control and Prevention (CDC), 97 percent of Americans have this chemical circulating in our bodies, as it can accumulate more quickly than our bodies can get rid of it.

Oxybenzone can permeate across the skin and accumulate in the blood, the kidneys, and the liver, and it may be toxic to liver cells. Read the article about the toxicological evaluation of Benzophenone. Another study done in 2007 with rats showed that there was some evidence of carcinogenic activity of Benzophenone in male rats. (One of the derivatives of Benzophenone is Oxybenzone)


Though SPF products are designed to protect skin from sun-induced aging, Octinoxate may be a culprit for premature aging, as it produces free radicals that can damage skin and cells. It has been detected in human urine, blood, and breast milk, which indicates that humans are systemically exposed to this compound. Octinoxate increases cell proliferation in cells that grow in response to estrogen exposure. Lifetime estrogen exposure is an established risk factor in the development and progression of breast cancer. Read more at


When this chemical is exposed to UV light, it absorbs the rays and produces oxygen radicals that can damage cells and cause mutations. It is readily absorbed by your skin and may accumulate within your body in measurable amounts. Plus, it can be toxic to the environment.

It is efficient at absorbing into the skin and can penetrate to the deepest layers of the skin. This deep absorption leads to interactions with other chemicals which cause changes deep in the skin, producing oxygen radicals that can lead to cell death and may be implicated in cardiovascular disease.


It is less of a health and safety concern than other sunscreen ingredients like Oxybenzone, but Japan’s Standards for Cosmetics has restricted its use in certain types of cosmetics. Health concerns associated with exposure to Octisalate include immune effects and allergenic effects.


A very common ingredient in FDA approved chemical-based sunscreens.  It is often used in replace of Oxybenzone but is still holds with it similar risks associated with Oxybenzone.  

This ingredient works the same as Oxybenzone in that it penetrates the skin and increases free radicals in the skin which increases the risks of types of skin cancer as well as photo contact allergies to sunscreens. Research shows Avobenzone reacts with chlorine and might cause toxic reactions.


This UV-absorbing sunscreen ingredient helps sunscreen to penetrate your skin. Once the ingredient has been absorbed, Homosalate accumulates in our bodies faster than we can get rid of it, becomes toxic, and disrupts our hormones.

Homosalate at a maximum concentration of 10% or less does not pose a risk EU scientific Committee concluded, however, I wouldn’t want this ingredient to accumulate in my body as I apply sunscreen every day!

Retinyl Palmitate

As an ingredient in sunscreen, its function is to improve the product’s performance against the aging effects of UV exposure, However, certain forms of vitamin A found in sun protection products—namely Retinyl Palmitate can be cause for concern.

When exposed to the sun’s UV rays, retinol compounds break down and produce destructive free radicals that are toxic to cells, damage DNA, and may lead to cancer. FDA studies have shown that Retinyl Palmitate may speed the development of malignant cells and skin tumors when applied to the skin before sun exposure, so steer clear of skin sun products that harbor the stuff. National Toxicity Program study on Retinyl Palmitate.


Para Amino Benzoic Acid was introduced in the 1970s as a UVB filter. More recently, its use has declined due to allergic dermatitis, photosensitivity, and a tendency to stain clothing. Some research links PABA with thyroid-disrupting activity, raising concerns about long-term health effects.

Currently, PABA derivatives are used in place of PABA, but these derivatives may also cause health problems. The most commonly used PABA derivative is Padimate O (OD-PABA) which may disrupt endocrine activity. PABA does cause some health problems such as endocrine disruption, sensitization, and bioaccumulation. Read more here
