In this short series about harmful ingredients in personal care products, this installment highlights five ingredients to avoid. At the end of the article I list a few brands I personally use and trust.
5 Personal Care Ingredients to Avoid: Part 3
Part 1: 5 Personal Care Ingredients to Avoid and Why
Part 2: 5 Personal Care Ingredients to Avoid: Part 2
1. Hydroquinone
Hydroquinone, once used in black-and-white photography developers, is still present in some skin-lightening creams. It has been banned in several countries and, in 2006, the US re-evaluated its over-the-counter approval after safety tests raised concerns about potential carcinogenic effects. Because it may still appear in prescription or specialized formulations, check labels and ask questions before using products that claim to lighten skin or target dark spots.
2. Methylisothiazolinone and methylchloroisothiazolinone
These two preservatives are commonly used in water-based personal care products—shampoos, conditioners, lotions, sunscreens, and body washes—to prevent bacterial growth. They have been identified as cytotoxins and are known to cause irritation to the skin, eyes, and respiratory system. Although several countries have restricted their use, they remain present in many products sold in the United States, so consider alternatives when possible.
3. Oxybenzone
Oxybenzone is used in many sunscreens and SPF-containing moisturizers because it absorbs ultraviolet light. However, the compound is readily absorbed by the body and has been detected in a large portion of the population. It has been associated with skin irritation, allergic reactions, and concerns about endocrine disruption. If you prefer chemical sunscreens, read labels carefully and weigh risks versus benefits; mineral sunscreens with zinc oxide or titanium dioxide are a common alternative.
4. Petrolatum (petroleum jelly)
Petrolatum is a semi-solid mixture of hydrocarbons derived from petroleum. It’s used as a moisture barrier in lip balms, lipsticks, moisturizers, and as a shine agent in some hair products. Contamination with polycyclic aromatic hydrocarbons (PAHs) is a concern because PAHs are linked to cancer risk. Some users also report that long-term use may contribute to skin aging. If you choose products with petrolatum, look for brands that specify pharmaceutical- or cosmetic-grade petrolatum and rigorous purification standards, or opt for plant-based emollients instead.
5. Cyclopentasiloxane
Cyclopentasiloxane is a silicone-derived ingredient commonly found in hair sprays, serums, and sunscreens. It provides a smooth, silky feel and helps spread products evenly, but it has been flagged for potential endocrine-disrupting effects and environmental persistence. If you prefer to avoid silicones, look for silicone-free labels or products that use natural conditioning agents.
Safer Options
Below are a few brands I trust for cleaner beauty and personal care products. These companies avoid many of the ingredients covered in this series and follow stricter ingredient standards. I list them here so you can explore their product ranges directly.
Beautycounter
My go-to for safer anti-aging skincare, shampoo and conditioner options, activated charcoal cleansing bars, and a selection of performance-based makeup. They emphasize ingredient transparency and avoid many controversial chemicals.
Primally Pure
Known for natural deodorants, body butters, facial toners, and nourishing lip balms. I appreciate their simple ingredient lists and effective formulations.
Primal Life Organics
Great for specialty spa-style products, including treatments like Fire & Ice skin products and vitamin C serums. Their offerings focus on natural, handcrafted formulations.
FATCO
Beloved for face oils, oil cleansers, and tallow-based moisturizers. Their products are rich and emollient, suitable for those seeking traditional, nutrient-dense ingredients.
