Our Pick
Isoi
Higher editor rating (8.6 vs 7.6)
Mario Badescu
Mario Badescu Skin Care is the New York dermatology institution that built the iconic Drying Lotion in the 1960s and has sold roughly the same product line, in roughly the same packaging, ever since. Romanian aesthetician Mario Badescu opened his Manhattan facial salon in 1967, formulated his own products for clients, and accidentally built one of the longest-running indie skincare brands in the US. The Drying Lotion (salicylic acid + sulfur + zinc oxide settled at the bottom of a glass bottle, dabbed onto pimples with a Q-tip) remains the brand's #1 best-seller and one of the most iconic spot treatments in skincare history. The Facial Sprays (Aloe, Herbs & Rosewater; Cucumber, Green Tea & Aloe) are cult-following beloved despite being fragrance-heavy and arguably unnecessary. Best for spot treatments and the Drying Lotion specifically; the rest of the line is a mixed bag of effective and dated. Cheap enough to experiment with, iconic enough to keep on the shelf.
Pros
- โ Drying Lotion is a 60-year cult acne icon that genuinely works on whiteheads
- โ Sephora-exclusive availability with consistent stocking
- โ broad budget-friendly range covers most concerns
- โ NYC family-owned heritage with continuous formulation
Cons
- โ fragrance-heavy across the entire line
- โ many formulations feel dated (alcohol-forward toners, heavy creams)
- โ marketing is uneven โ some products work brilliantly, others underwhelm
- โ has been sued multiple times for hidden steroid contamination in older formulations (resolved)
Isoi
Isoi has been quietly excellent for nearly two decades, but 2025 is its breakout year. The Blemish Care Up Serum picked up multiple Hwahae nods, and dermatology-leaning K-beauty fans have been quietly recommending it for fading post-acne marks for years. Premium-leaning but worth it.
