Buying cotton pads in bulk from Costco can be a worthwhile investment, especially if you use them frequently in your skincare routine. However, it's not just about the quantity; the quality of the cotton pads is equally important.

Cotton pads are often used for applying toners, removing makeup, or even for gentle exfoliation. Therefore, they need to be soft, absorbent, and durable. Low-quality cotton pads can be harsh on the skin, causing unnecessary irritation and redness.

When considering a bulk purchase, you should also consider the environmental impact. Cotton farming requires a significant amount of water, and the use of pesticides in conventional cotton farming can be harmful to the environment. Therefore, it would be beneficial to look for cotton pads made from organic cotton, which is grown without the use of synthetic pesticides and fertilizers.

In terms of cost-effectiveness, buying in bulk from Costco can indeed save you money in the long run. However, it's essential to ensure that you are getting a product that aligns with your skincare needs and values.

In conclusion, bulk purchases of cotton pads from Costco can be worth it if the product is of high quality, aligns with your skincare routine, and meets your environmental standards.
