SLC Acne Bar contains salicylic acid and lactic acid, which help exfoliate the skin and may improve the rough, bumpy texture of keratosis pilaris. As a rinse-off product, it has minimal absorption and is generally considered low risk during breastfeeding when used only on affected areas. However, postpartum hormonal fluctuations can increase skin sensitivity, making you more prone to dryness or irritation. Use it cautiously, rinse thoroughly, and strictly avoid the breast area to prevent your baby from touching or ingesting any residue. Crucially, any keratosis pilaris treatment should be performed under a doctor's supervision, especially while nursing.
