For people with Acne
HelloSkin’s experts could not find any clinical data on the use of Bioré Baking Soda Pore Cleanser in people with acne. However, the product contains salicylic acid which is commonly used in products for acne treatment, and thought to help limit clogging of pores and also alleviate hyperpigmentation.
For instance, in a 4 week cross-over study of 30 patients with mild-to-moderate acne, a 2% salicylic acid cleanser was reported to reduce the number of comedones compared with when using a 10% benzoyl peroxide wash (1). Also, a study based on 44 patients with dark skin type (known to be at increased risk of developing post-inflammatory hyperpigmentation), salicylic acid showed to benefit this. After applying a 20% salicylic acid gel combined with 10 % mandelic acid gelin during six sessions, the area with hyperpigmentation decreased by 60 %(2).
Also, excess sebum is one of the main factors that are known to be involved in acne pathogenesis (3). Salicylic acid in (very) high concentrations in an exfoliator has been shown to effectively reduce sebum secretion (4). In cosmetic products the concentration of salicylic acid must not exceed 2%. Still, salicylic can cause mild side effects such as mild, local irritation, so be aware when starting up this product. If you notice any redness or worsening of your acne, you should consider to try out another product.
This product also contains both sodium laureth sulfate and fragrances, both of which can irritate sensitive skin further (5, 6). Therefore it is important to thoroughly rinse off the cleanser after use.
