New Feature: Price History
Price history for known retailers is now active. When looking at a product page, you can now have an overview of the price history of each retailer offering.
We are currently tracking 4 main retailers as a trial run:
- Ulta (US)
- ChemistWarehouse.au (AU)
- SokoGlam (US)
- SpaceNK (UK)
This lets feature lets you check if products are truly on sale, as some not-so-very-ethical online retailers may increase their prices over time just before a sale, so that they can draw in more customers with bigger discounts (since they can claim “it really is 70% off the sticker price!!!”).
At PillowSkin, we (or rather, I, but I’m sure you do too!) detest such dishonesty, and I hate marketing lies, and this price history feature should let you be much more informed when buying products.
Additionally, you might have noticed from the image that there are different types of product variations being shown. This is currently one of the limitations, as these different variations are not actually directly comparable, so it would be a little misleading to lump them all together. For example, travel-sized offerings should be separated from bundled offerings, and from product-only offerings, and so on.
Metrics Algorithm Improvement
As of now, the product metrics are calculated by modelling ingredient data from studies, and mapping them out onto a scale. The strength of a product’s ingredient combinations are then determined based on this scale. If the exact ingredient strength is unknown, an estimation is calculated, based on its relationship between other ingredients as mentioned in studies.
The previous iteration of the algorithm was not very accurate, and this current iteration should now be an order of magnitude more accurate. However, there are still some issues that are limiting it, such as situations where there are multiple conflicting ingredient combinations, or when there is limited data.
Expect it to get better with time
