The Guru Index verdict
Mixed
~Mixed · 61%What the gurus are saying
Gurus acknowledge SK2's luxury status and celebrity appeal but split on whether it justifies the $200+ price tag. The core debate: while fermented ingredients do offer hydration and priming benefits, identical or near-identical formulations exist for a fraction of the cost. Praise centers on effectiveness as a moisture-locking primer, but frustration with the wasteful dropper packaging and premium pricing is consistent across reviewers.
