This Natural Skincare Formulation Certificate (DIY Skincare Formulation) is designed for absolute beginners with no prior experience, suitable for anyone interested in natural skincare. The 4-hour course covers four core areas: application and functions of basic skincare raw materials (plant extracts, oils, emulsifiers, preservatives – both natural and synthetic, including pairing techniques); contraindications and precautions (ingredient mixing restrictions, pH and temperature control); formula design and calculation methods; and practical mixing and production techniques. All materials and tools are included in the tuition – students need not bring anything. Students will complete three products: hand cream (100ml), body cream (100ml), and lip balm (2×4ml). Assessment is based on class participation and practical performance – no written exam, exam fees are waived. Upon completion, students receive the IQA Natural Skincare Formulation Certificate. Ideal for those who enjoy handmade skincare, pursue natural zero-burden products, and wish to learn skincare formulation skills.
