Frequently Asked Questions How does stable vitamin C compare to regular vitamin C? + Tetrahexyldecyl ascorbate (the form in VC Serum) is oil-soluble and highly stable — it penetrates deeper, doesn't oxidize quickly, and causes less irritation than L-ascorbic acid. It brightens effectively, supports collagen, and works well for oily/combination skin without stinging. Will this help with enlarged pores and texture? + Yes — vitamin C (tetrahexyldecyl ascorbate) refines texture and minimizes pore appearance over time by boosting collagen and exfoliating gently at the surface. Lilac stem cells support renewal for smoother skin. Consistent use (8–12 weeks) shows noticeable improvement in pores and overall smoothness. Is this serum suitable for oily or acne-prone skin? + Yes — it's lightweight, non-greasy, and oil-free in feel. The stable vitamin C brightens without clogging pores, and hyaluronic acid hydrates lightly. It's ideal for normal/oily/combination skin that wants brightening without heaviness or breakouts. Can I use this with retinol or other actives? + Yes — vitamin C and retinol pair well. Use VC Serum in the morning (great with SPF) and retinol at night. The antioxidants in VC Serum help buffer retinol irritation. Always patch test combinations and use sunscreen daily. Is this pregnancy safe? + We always recommend consulting with your physician or OB-GYN before using any active skincare products during pregnancy. VC Serum contains stable vitamin C and peptides with no harsh acids or retinoids, but your doctor knows your specific situation best. Have that conversation and follow their guidance. How does lilac stem cell extract work? + Lilac stem cell extract (Syringa vulgaris) promotes skin renewal and firmness by signaling cells to behave more youthfully. It supports collagen production and helps improve texture & tone. Combined with vitamin C, it enhances brightening and anti-aging effects without irritation.
