| Verdict | Emma Lewisham's hydration hero — a multi-weight hyaluronic acid serum boosted with tremella mushroom polysaccharide (holds more water per molecule than HA), squalane for lipid-layer reinforcement, and centella asiatica for barrier repair. The 72-hour hydration claim comes from clinical trials the brand published — unusual transparency in luxury skincare. Refillable packaging maintains the carbon-positive commitment. The price is premium but the formula competes with serums at twice the cost. | Clinical 12.5% L-ascorbic acid at $50. Half the Sunday Riley price, full strength. |
