Side by side
Arencia Retinal Booster Shot and Dr. Althea 0.1% Gentle Retinol Serum side by side
Pairs follow a published formula: same category, both ingredient lists read and at least one price each, one of the two among its category's 50 cheapest or the 50 with prices from the most stores, and neither a set, gift box or mini size. The two share at least two key ingredients, or one and a price per 100 ml in the same range (the dearer at most 2.5 times the other). The most alike pairs come first.
