Recommendation Algorithm

The Recommendation System offers two display options:

• Routine View: Products are grouped into a step-by-step skincare routine.

• List View: Products are displayed as a simple, scrollable list without grouping.

Choose the option that best fits your use case or user experience goals.

Common Steps

This part describes an algorithm for selecting recommendations based on user tags and product tags.

The recommendation selection algorithm works as follows:

• Step 1

  • System selects all products that have a skin type tag that matches the user's skin type.

  • If the user's skin type is not among the skin type tags of the product, such a product is not recommended to the user under any circumstances.

• Step 2

  • The system checks if the user has skin concerns tags and selects all products that have at least 1 tag corresponding to the user's skin concerns.

  • The system selects all products without skin concerns tags (basic care products).

  • If the product has concern tags, but there is no overlap between these tags and the concern tags of the user, such products are not recommended to the user under any circumstances.

• Step 3

  • The system sorts products by priority.

• Step 4

  • The system sorts products by the number of matches of skin concerns tags with the user's skin concerns.

• Step 5

  • The system sorts products by price.

• Step 6

  • The system selects the top 10 products in each category.

• Step 7: this step is different for the different type of view. Check the description:

  • Routine View

    • Main routine

      • For each category, system selects the top product.

      • If this product has only one tag (AM or PM), a pair is selected as follows:

        • In the same category, the next highest priority product with the opposite tag (AM or PM) is selected to form a pair.

        • If such a product is not available, a product with both tags (AM and PM) is selected.

        • If no suitable product can be found according to the conditions above, no pair is assigned for this product.

    • Promo product

      System selects all the product with the tag "Promo" and then selects 1 product as follows:

      • Not included in the routine

      • Highest priority

      • Highest price

    • "You may also like" block This block includes all the recommended products that are selected but not presented in the routine. The order of selection of goods is determined by the following sorting sequence:

      • Priority

      • Concerns covered (optional)

      • Price

  • List View

    • The system shows all recommended products as a list based on the order defined in step 6
