Ascorbic acid is water soluble so you’ll generally see it in water based serums. Only oil soluble C derivatives like tetrahexyldecyl ascorbate will be in a lipid based serum. **Q: When will this product be in stock again?** A: I need to know this also **Q: Will using this help my rocesea?** A: Great question! I also have rosacea (mine is mild) but I haven’t noticed a difference. I can say it hasn’t made my rosacea worse, however. To give you more insight on this serum I can tell you that this formula is a bit on the thicker side (more nourishing than others) and isn’t as drying which I need to help clear my particular acne. Some brands are better for certain acne than others, so personally I’m going to be switching to another brand. But I’ve found no difference between brands in regards to rosacea. But again, my rosacea is mild. Hope this is somewhat helpful to you! ## Frequently Bought Together - Vitamin C 15% Serum with Arbutin for Face - Brightening Facial Serum with Aloe - Professional Formula for All Skin Types, 1 Fl Oz (30ml) - Pure Hyaluronic Acid 1% Serum 10,000ppm - Hydrating Face Serum for Fine Lines - Intense Moisture Facial Serum for Visibly Plumped Skin, 2 Fl Oz (60ml) - Retinol 2.5% Solution Facial Serum with Vitamin E - Facial Crepe Erase, Age Spot Remover, High Strength Solution for Face without a Prescription, 2 Fl Oz (60ml) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/469442251-vitamin-c-facial-serum-with-l-ascorbic-acid-15-vitamin](https://www.desertcart.jp/products/469442251-vitamin-c-facial-serum-with-l-ascorbic-acid-15-vitamin) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-23*
