If Lumière Glass-Skin Serum is out of stock, over budget, or not the right fit for your skin type, these are the closest alternatives our editors have tested.
Best overall alternative
[Brand X] Brightening Serum — closest in texture and effect. Same copper-peptide feel, slightly lower concentration, $32.
Budget alternative
The Ordinary Vitamin C Suspension 23% — not as elegant, but the actives stack up. Best for experienced users who tolerate tingle.

Sensitive-skin alternative
[Brand Y] Gentle C Serum — formulated for reactive skin. No fragrance, low pH, niacinamide-paired to buffer the vitamin C.
Premium upgrade alternative
[Brand Z] Gold Standard C+E Ferulic — the benchmark. More expensive, faster results, but the core mechanism is the same.
