Department store skin products can be harmful due to the following reasons:

1. Chemical Additives: Many department store products contain synthetic chemicals, such as parabens, sulfates, and artificial fragrances. These additives can irritate the skin, disrupt hormones, and lead to long-term health issues.
2. Low-Quality Ingredients: While some products may include beneficial ingredients, they are often in small amounts, diluted with fillers or other less-effective substances that can reduce the product’s efficacy.
3. Harsh Preservatives: To ensure a long shelf life, many products are formulated with harsh preservatives like formaldehyde-releasing agents and synthetic antimicrobial agents. These can cause skin irritation, allergic reactions, and other health concerns.
4. Synthetic Fragrances: Artificial fragrances are commonly added to make products smell appealing, but they often contain undisclosed chemicals that can trigger allergic reactions, irritate the skin, and disrupt the endocrine system.
5. Unknown or Long Ingredient Lists: If a product has an overly long list of ingredients with complex chemical names, it likely contains substances that are unnecessary or potentially harmful.
6. Lack of Transparency: Some brands do not disclose the exact composition of their products, making it difficult for consumers to know what they are putting on their skin.

Overall, many department store products prioritize cost-effectiveness and shelf stability over the quality and safety of ingredients, which can compromise skin health over time. Opting for products that use high-quality, natural, and transparent formulations, like those found in premium essential oil blends, can be a safer and more beneficial choice for the skin.
