Sea Kelp Extract for Combination Skin

Regarding your question about using Sea Kelp Extract on combination skin and the concern about it being too moisturizing, based on the product information, Sea Kelp Extract is described as being able to help maintain balance for all skin types, including sensitive skin. It provides moisture and nourishment.

The recommended usage rate for skin care is 1-3%, although it can be used up to 10%. Using it at 5% in a gel formula is within the maximum allowed range, but it is higher than the typical recommended amount for skin care (1-3%). As the staff mentioned, whether to include it and at what concentration depends on the specific needs of your skin and if you require additional moisture.

While the product description suggests it's suitable for all skin types, if you have combination skin that is prone to oiliness in some areas, using a higher concentration like 5% might feel too rich, especially if your gel formula already contains other moisturizing ingredients. You could start with a lower concentration (e.g., 1-3%) and see how your skin responds, adjusting as needed.

Also, please note that using Sea Kelp Extract at a high rate (above the recommended 1-3%) can potentially result in a fishy smell in the final product.
