Description
Our powerful brightening face serum is infused with a potent, all-natural 20% vitamin C stabilized for maximum efficacy and tolerability. Composed of 99.9% ingredients of natural origin, this dark spot serum features ascorbyl tetraisopalmitate, an all-natural, oil-soluble form of vitamin C derived from green science. Our antioxidant face serum helps defend against environmental skin aging and supports the body’s collagen synthesis to help firm skin. Native turmeric and pomegranate cells help intensify the multi-corrective actions of the vitamin C as they combine to help improve skin firmness and unify skin tone by minimizing the appearance of dark spots and illuminating the complexion. Apricot kernel oil, rich in phytosterols, helps moisturize and comfort skin.

Frequently Asked Questions
What is the most effective vitamin C serum?
Serum Vitamine C is one of the most effective vitamin C serums available from Yon‑Ka Paris for brightening and anti‑aging results. It delivers a potent, stabilized 20% vitamin C as ascorbyl tetraisopalmitate—an oil‑soluble form chosen for stability and skin tolerability—while combining native turmeric and pomegranate cells to enhance multi‑corrective action and apricot kernel oil to moisturize. Those formulation choices help defend against environmental aging, support collagen synthesis, and visibly unify skin tone. This serum suits anyone seeking high‑strength antioxidant protection and targeted dark spot correction. However, if your pigmentation is more pronounced, professional spa treatments can help intensify the results.
Is Serum Vitamine C good for sensitive skin?
Yes — Serum Vitamine C is formulated to be well tolerated by sensitive skin. Instead of unstable, highly acidic L‑ascorbic acid, it uses an oil‑soluble, stabilized 20% ascorbyl tetraisopalmitate which is less likely to sting or oxidize on the skin, and the formula is 99.9% of natural origin with soothing apricot kernel oil to comfort and nourish. These features reduce irritation risk while delivering brightening and antioxidant benefits. This makes it ideal for people with reactive or easily irritated skin who still want a potent vitamin C. That said, any high‑potency active can cause sensitivity in some individuals, so perform a patch test and introduce it gradually.
How does Serum Vitamine C compare to traditional L‑ascorbic acid serums?
Serum Vitamine C differs notably from traditional L‑ascorbic acid serums in stability, tolerability, and delivery. Its 20% ascorbyl tetraisopalmitate is oil‑soluble and stabilized for prolonged efficacy and less oxidation, allowing gentler, deeper lipid‑phase penetration compared with water‑soluble L‑ascorbic acid which can be more acidic and unstable. Yon‑Ka’s formula also pairs vitamin C with turmeric and pomegranate cells to augment brightening and antioxidant effects and apricot kernel oil for hydration. This makes it better suited for dry or sensitive skin seeking long‑term brightening and firming. However, some users notice quicker surface brightening with high‑strength L‑ascorbic acid powders or serums; choose based on your skin tolerance and desired speed of results.
Will Serum Vitamine C help reduce dark spots and hyperpigmentation?
Yes, Serum Vitamine C is designed to help minimize the appearance of dark spots and even skin tone. The formula’s 20% stabilized vitamin C supports the skin’s natural collagen synthesis and inhibits pigment formation pathways, while native turmeric and pomegranate cells provide complementary multi‑corrective and antioxidant actions to intensify brightening. Regular, consistent use typically leads to progressive evening of complexion and diminished spot visibility. This product is especially beneficial for sunspots, post‑inflammatory marks, and general discoloration. That said, deeper or longstanding hyperpigmentation may require combined approaches—professional in‑office procedures or targeted depigmenting protocols—alongside daily topical care for optimal results.
How long does one bottle of Serum Vitamine C last with daily use?
A single bottle of Serum Vitamine C will typically last several weeks to a few months depending on how much you use: applying 1–2 drops once daily will stretch a standard serum bottle (commonly around 30 mL) to roughly 2–3 months, while twice‑daily application will shorten that span. The concentrated nature of this serum means a small amount delivers potent results, so a little goes a long way. This estimate suits everyday users seeking brightening and antioxidant benefits. If you travel often or prefer smaller formats, Yon‑Ka also offers a travel size for shorter trips. Keep in mind usage frequency and drop size will change exact longevity.
Can I use Serum Vitamine C with retinol or other active ingredients?
Yes — you can use Serum Vitamine C alongside retinol and other actives, but timing and layering matter for comfort and efficacy. For most routines, we recommend vitamin C in the morning to provide antioxidant protection against daily environmental stressors and retinol in the evening to support cellular renewal; this separates potent actives and reduces irritation risk. Serum Vitamine C’s oil‑soluble, stabilized vitamin C pairs well with hydrators and sunscreens, and using sunscreen daily is essential when combining actives. This approach benefits those pursuing comprehensive anti‑aging regimens. If you have very reactive skin, introduce one active at a time and space applications to assess tolerance.
How should I incorporate Serum Vitamine C into my skincare routine?
Apply Serum Vitamine C in the morning after cleansing and toning and before moisturizer and sunscreen for best antioxidant protection during the day. Dispense six drops, warm gently between fingertips, and press into the skin to encourage lipid‑phase absorption; follow with moisturizer and broad‑spectrum SPF. Using it in the morning helps shield skin from environmental damage and complements sunscreen performance, while evening use is also acceptable if you prefer nightly brightening. This routine suits anyone wanting visible radiance and anti‑aging support. If using multiple serums, layer from thinnest to thickest texture; for example apply Advanced Optimzer Serum first, then layer Serum Vitamine C overtop.
Is Serum Vitamine C suitable for men?
Yes, Serum Vitamine C is suitable for men. The formula is gender‑neutral and targets universal skin concerns—dullness, uneven tone, loss of firmness, and environmental aging—using a high‑potency 20% stabilized vitamin C, turmeric and pomegranate cells, and nourishing apricot kernel oil. Its sensory profile and rapid absorption work well in men's grooming routines, whether used after shaving to brighten and soothe or as part of a daily anti‑aging regimen. Men with dry, sun‑exposed, or mature skin will particularly benefit. Apply after cleansing and toning; can be used underneath your daily moisturizer.
What makes Serum Vitamine C different from other Yon‑Ka serums?
Serum Vitamine C stands out in the Yon‑Ka Paris collection for its concentrated 20% stabilized vitamin C delivered as oil‑soluble ascorbyl tetraisopalmitate and its 99.9% natural origin formulation. This serum is specifically crafted for brightening, dark‑spot correction, antioxidant defense, and firming thanks to added native turmeric and pomegranate cells and nourishing apricot kernel oil. It reflects Yon‑Ka’s spa‑grade sensorial approach while targeting multi‑corrective results. If your primary goal is intense brightening and antioxidant protection, this serum is highly recommended.
Is Serum Vitamine C travel‑friendly and how should I store it?
Yes — Serum Vitamine C is travel‑friendly: Yon‑Ka offers a travel size for portability, and the oil‑soluble, stabilized vitamin C format is less prone to oxidation compared with unstable water‑based vitamin C serums. For best preservation, store the bottle in a cool, dark place away from direct sunlight and extreme heat, and keep the cap tightly closed between uses. This guidance is ideal for frequent travelers or those who value long‑term potency. Be mindful that once opened, high‑strength actives have a finite shelf life, so it is recommended to use the product within six months of opening.
