Your client has post-inflammatory hyperpigmentation and inflamed acne. Which product should NOT be used?

The appropriate choice for a product that should not be used when a client has post-inflammatory hyperpigmentation and inflamed acne is a Vitamin A Corrective Serum. This type of serum, which often contains retinoids, can exacerbate inflammation and cause irritation, especially in individuals with inflamed acne. Using such a product on already inflamed skin may lead to increased redness, sensitivity, or discomfort, making it counterproductive in the context of treating both the inflammation and the hyperpigmentation.

In cases of inflamed acne, it is crucial to opt for gentler, more soothing ingredients that can help calm the skin while addressing the hyperpigmentation. On the other hand, products like Mandelic 5%, Glycolic 5%, and Salicylic acid are typically formulated to manage acne conditions effectively. These ingredients work by promoting exfoliation, reducing bacteria, and healing the skin, making them more suitable for use in this scenario.
