Evening-Only or Alternating Use
Some users apply it only at night or alternate with gentler vitamin C products to minimize irritation risk, particularly those with sensitive or reactive skin.
High Concentration Requires Acclimatization
Multiple reviews note users apply small amounts (few drops) that go a long way, and beginners with vitamin C experience mild tingling initially—a sign reviewers interpret as efficacy rather than damage.
Refrigeration Requirement

Mixing & Layering
Users report mixing it with other lotions or creams, and layering it under light day creams or moisturizers without stickiness concerns once properly absorbed.
