The problem for many lies in tolerance: classic vitamin C serums based on pure ascorbic acid can sting, feel burning, or even cause irritation in sensitive skin. Those who want to benefit from vitamin C without this downside need a different delivery system — a lipid-soluble derivative instead of the water-soluble acid.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eCosmedix BrillianCy is a facial oil that follows this exact path. The formula combines tetrahexyldecyl ascorbate — an advanced, oil-soluble vitamin C derivative — with elderberry extract, hops, rice bran, and rosemary. The texture is lightweight and silky smooth, absorbs completely without a greasy film, and is loved by over 194 users with an average rating of 4.7 stars. A face oil that doesn’t feel like a face oil, and with more than 140 five-star reviews, it is among the most highly rated products in the Cosmedix range.\u003c\/p\u003e\n\u003ch2 class=\"text-text-100 mt-3 -mb-1 text-[1.375rem] font-bold\"\u003eBenefits\u003c\/h2\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eHelps fade pigmentation spots and uneven skin tone\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eDelivers an instantly radiant, hydrated appearance to dull skin\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eReduces the visibility of fine lines and wrinkles\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eSuitable for sensitive skin thanks to mild vitamin C derivative\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eLightweight texture without greasy or sticky feeling\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eUsable both solo and layered under moisturizer and SPF\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eActive ingredients\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eTetrahexyldecyl Ascorbate:\u003c\/strong\u003e A lipid-soluble derivative of vitamin C that works differently from classic ascorbic acid. Water-soluble vitamin C has a low pH (around 3.5) that can irritate the skin, while tetrahexyldecyl ascorbate works at a neutral pH and is absorbed into the skin without irritation. Research shows that this form is absorbed up to 50 times more effectively by the skin than other vitamin C derivatives — an important reason why BrillianCy also delivers results for sensitive skin.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eElderberry extract (Sambucus Nigra):\u003c\/strong\u003e A traditional ingredient rich in anthocyanins, flavonoids, and vitamins.

First, stability: vitamin C in water-based formulas oxidizes quickly and loses its effectiveness — the serum that turns brownish-pink after a few weeks is visible proof of this. In an oil base, tetrahexyldecyl ascorbate is much more stable and retains its effectiveness until the last drop. Secondly, tolerability: oil-soluble vitamin C has a neutral pH and does not irritate, while pure ascorbic acid can feel burning or even cause redness for some.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cem\u003eDoes BrillianCy also work for oily or combination skin?\u003c\/em\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eYes, and that might be the most surprising aspect of this product. Despite being a facial oil, users with combination and even oily skin have repeatedly reported that BrillianCy does not cause breakouts or leave a greasy shine. The light texture based on caprylic\/capric triglyceride is non-comedogenic. For very oily skin, targeted use is recommended — two drops in the evening, instead of during the day.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cem\u003eCan I use BrillianCy during pregnancy or breastfeeding?\u003c\/em\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eYes. The formula contains no retinoids, salicylic acid, or other ingredients that are discouraged during these periods. For those looking for a safe brightening option during pregnancy or breastfeeding — times when melasma often first appears — BrillianCy is an excellent choice.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cem\u003eWhen will I see the first results?\u003c\/em\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe immediate moisturizing and radiance effects are noticeable after just a few days — the skin feels softer and smoother. For visible improvement of pigmentation spots, dull complexion, and skin tone, daily use for two to four weeks is recommended. For structural results on stubborn pigmentation or melasma, eight to twelve weeks may be needed — pigmentation spots take time, even with the best ingredients.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cem\u003eCan I combine BrillianCy with retinol or acids?\u003c\/em\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eYes, and they even work excellently together. Classic routine: in the morning BrillianCy followed by SPF (vitamin C works synergistically with sunscreens), in the evening a retinol serum like Define or Refine. Or both morning and evening. The mild vitamin C derivative in BrillianCy does not cause 'over-exfoliation' when combined with other actives.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cem\u003eWhat is the difference between BrillianCy and Simply Brilliant?\u003c\/em\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eTwo different approaches to the same goal. Simply Brilliant is a concentrated watery serum with ten brightening ingredients including niacinamide, lactic acid, salicylic acid, and Whitonyl — strong effect with some exfoliation. BrillianCy is a mild facial oil focusing on vitamin C and antioxidants, without exfoliating acids. For those seeking faster results on stubborn pigmentation, Simply Brilliant is more intensive; for sensitive skin or daily use over years, BrillianCy is the more pleasant choice.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cem\u003eDoes BrillianCy feel sticky or greasy on the skin?\u003c\/em\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eAccording to most users, not at all — the silky feel and quick absorption are actually among the most praised features in the reviews. Some individual users do report a slight sticky feeling, often when using too many drops or combining with other heavy products. Two to four drops are enough for the entire face — more is not better in this case.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cem\u003eHow long does a 30ml bottle last?\u003c\/em\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eWith daily use, two to four drops per application, a bottle usually lasts three to four months. Using it both morning and evening reduces this to one and a half to two months. The dropper allows precise dosing, which prevents waste.\u003c\/p\u003e","brand":"Cosmedix","offers":[{"title":"Default Title","offer_id":56635822539083,"sku":null,"price":108.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1009\/6908\/7307\/files\/2815695bb03fe62e2a04496f8bea03bfe2ce292c.jpg?v=1779224493","url":"https:\/\/webshop.glamskin.nl\/en\/products\/cosmedix-brilliancy-30ml","provider":"Glam Skin Webshop","version":"1.0","type":"link"}
