Hi Corner Beauty team 😊 Thank you for your interest in ZENA Cosmetics! We have both professional treatment products and retail/homecare products. Some products can be sold directly in stores without training, especially homecare and skincare items. However, professional products such as our Natural Algae Peeling and stronger acid protocols require official education and certification, as they are designed for professional aesthetic use. You can explore our products and brand here: Instagram: @zena.cosmetic Website: https://zenacosmetics.com We can also send you our catalog and help recommend which products would be most suitable for your store or clinic concept 👍 Please let us know a little more about your business and what type of products you are most interested in. Warm regards, Julia ZENA Cosmetics
