爱尔兰采购需求：最佳面部保湿霜、抗衰老精华液、敏感肌洁面乳、天然面膜、祛痘产品、保湿面霜

I'm interested in understanding how you determine wholesale price gradients for bulk orders. Specifically, for the sunscreen product, I'm looking for formulations that provide moisturizing benefits, a glass skin effect, and are non-greasy and easy to absorb for various skin types. Could you send me some samples, either in pouches or tubes, for evaluation? Additionally, if you have a catalog of your products, I would appreciate it if you could share that as well. Thanks!
