| Verdict | 10% L-ascorbic acid + THD ascorbate — strong vitamin C with a less-sting delivery. | 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. |
