What is the statistic tuning value to remove acne?

Hello, I am trying to create a mod that can remove acne when applied but I can't really read the statistic tuning for acne to know what value removes acne.

There are these two statistics:

<?xml version="1.0" encoding="utf-8"?>

<I c="BodyTypeLevelCommodity" i="statistic" m="sims.body_type_level.body_type_level_commodity" n="bodyTypeLevelCommodity_Acne" s="281711">

</I>

Please help.
