Things to Be Aware Of: COSRX Lip Sleep Ceramide Lip Butter Sleeping Mask

 
CreamScan AI identified a few things to consider before adding COSRX Lip Sleep Ceramide Lip Butter Sleeping Mask to your skincare routine:
 

Best for Very Dry Skin - May Be Too Thick for Other Skin Types

With exceptional occlusivity, this product is optimal for moisturizing dry and very dry skin but may be too thick for other skin types, including normal, and especially combination and oily skin.

If you have oily, combination, or normal skin and are considering purchasing this product for the first time, it might be a good idea to try a sample before buying.

Needs to Be Paired with Extra Humectants for Optimal Moisturizing Efficacy

An ideal moisturizer for any skin type should balance the right level of occlusivity (depending on skin type) with a significant amount of humectants, while COSRX Lip Sleep Ceramide Lip Butter Sleeping Mask contains a low level of humectants.

People with dry skin would definitely benefit from adding more humectants to their moisturizing routine beyond what this product offers. If this is your only moisturizer, it may be worth including a humectant-rich product, such as a serum, in your skincare routine.
