iFEiER Pure Salicylic Acid Powder is a cosmetic-grade ingredient supplied in a 250g (8.82 oz) container. This product consists solely of original salicylic acid in powder form, intended for use in DIY skincare, body care, hair care, and the formulation of salicylic serums and BHA treatments. Salicylic acid is a beta hydroxy acid (BHA) known for its ability to exfoliate the skin by penetrating oil-filled pores, helping to remove dead skin cells and reduce excess sebum. It is commonly incorporated into formulations targeting oily, combination, and acne-prone skin types. The powder format allows users to control the concentration and customize their own products, such as toners, masks, spot treatments, or scalp exfoliants. This ingredient should be handled with care: it must be properly dissolved in a suitable solvent (e.g., alcohol, propylene glycol, or water with pH adjustment) before application, as direct contact with dry powder may cause irritation. The recommended usage concentration typically ranges from 0.5% to 2% for leave-on products, depending on skin sensitivity and intended purpose. Because salicylic acid is a keratolytic agent, it can also be used in formulations for callused skin on feet or elbows. For hair care, it may help clarify the scalp by reducing buildup. The product is free from additives, fillers, and preservatives, making it suitable for users who prefer to create tailored skincare solutions. Its large quantity offers long-term supply for regular DIY projects. As with any active ingredient, patch testing is advised prior to full use, and formulation guidelines should be followed to ensure safe and effective results.
