Dior Lip Oil: Is It Causing Darkened Lips?

Dior Lip Oil: Is It Causing Darkened Lips? A Cosmetic Chemist Weighs In Recently, social media users have reported that Dior Lip Oil has caused their lips to turn dark or purple. This has sparked concern among consumers and prompted a response from a cosmetic chemist. The chemist suggests that the discoloration may be a form of contact cheilitis, an allergic reaction to ingredients in the product. "Dior Lip Oil has been turning some users' lips black or purple," the chemist states. This issue appears to be linked to the presence of benzyl alcohol, a preservative found in some older formulations of the product. The chemist explains that while this ingredient is not present in the current formulation, it was included in versions dating back to at least 2021. Therefore, users who experienced discoloration may have been using an older version of the product. The chemist recommends several remedies for those experiencing this issue. These include using an SPF lip balm to protect against sun-induced hyperpigmentation and performing weekly lip scrubs to exfoliate the darkened skin. While the condition may take up to a year to completely resolve, the chemist emphasizes the importance of preventative measures and discontinuing use of any product that causes irritation. This situation highlights the importance of ingredient awareness and patch testing before using new cosmetic products. It also underscores the potential for even well-known brands to have formulation changes that may affect users differently.
