What is the shelf life of the 10% Vitamin C + E Ferulic Acid Serum?
For best results, we recommend using your 10% Vitamin C + E Ferulic Acid Serum within 3 to 6 months of opening, when it is freshest and most effective. As the serum begins to age, it will slowly appear darker in color due to the natural oxidation process.
For further guidance and customer consideration, the period after opening symbol is provided on the product box. Use upon receipt and refrigeration is suggested to assist with the shelf life of the product.

Can I use the 10% Vitamin C + E Ferulic Acid Serum under the eyes?
We do not recommend applying the 10% Vitamin C + E Ferulic Acid Serum serum directly to the under-eye area. The skin around the eyes is very delicate, therefore, we recommend using products specifically formulated for eye area instead.
How do I layer the 10% Vitamin C + E Ferulic Acid Serum with my other Timeless products?
As a general rule, apply products from thinnest to thickest. We do not recommend layering the 10% Vitamin C + E Ferulic Acid Serum with another active serum in a single routine.

Discontinue if irritation occurs. Store in a cool, dry place away from sunlight.
What is the consistency of the 10% Vitamin C + E Ferulic Acid Serum?
The water-like consistency of our 10% Vitamin C + E Ferulic Acid Serum allows the forumula to deeply penetrate the skin for optimal efficacy and layering.

We recommend use of this high-strength 10% Vitamin C + E Ferulic Acid Serum once daily for those with sensitive skin. For best results, use in your morning routine, followed by moisturizer and SPF. Alternatively, if use at night is preferred, avoid layering with other active ingredients.
For those with more tolerant skin, this product may be used twice a day. We do not recommend layering the 10% Vitamin C + E Ferulic Acid Serum with another active serum in a single routine.
Do all sizes of the 10% Vitamin C + E Ferulic Acid Serum come in the glass packaging?
While the 4oz 10% Vitamin C + E Ferulic Acid Serum remains in the plastic, each size offers an airtight pump, with the 1oz and 1.7oz sizes being available in the updated glass bottle.
What is the Timeless 10% Vitamin C + E Ferulic Acid Serum?
Our 10% Vitamin C + E Ferulic Acid Serum is a daily antioxidant facial serum formulated with 10% pure L-ascorbic acid (Vitamin C), Vitamin E, and Ferulic Acid. This combination helps brighten dull skin, improve uneven skin tone, support collagen production, and protect against environmental stressors like pollution and free radicals. The lower 10% concentration is ideal for beginners and those with sensitive skin.
Who should use the 10% Vitamin C + E Ferulic Acid Serum?
Our 10% Vitamin C + E Ferulic Acid Serum is recommended for anyone new to Vitamin C skincare, those with sensitive skin, or anyone looking to improve dullness, uneven tone, discoloration, and early signs of aging with a gentler concentration of pure Vitamin C.
What makes the combination of Vitamin C, Vitamin E, and Ferulic Acid so effective?
Vitamin C, Vitamin E, and Ferulic Acid work synergistically as antioxidants. Ferulic Acid helps stabilize Vitamin C while enhancing its antioxidant performance, and Vitamin E works alongside Vitamin C to provide additional protection against environmental damage caused by free radicals. This combination also helps improve the overall effectiveness of the formula.
Is the 10% Vitamin C + E Ferulic Acid Serum good for sensitive skin?
Yes. Our 10% Vitamin C + E Ferulic Acid Serum was developed as a gentler option for sensitive skin or first-time Vitamin C users. Its 10% concentration delivers antioxidant benefits while reducing the likelihood of irritation that can occur with stronger formulas.
Can I use the 10% Vitamin C + E Ferulic Acid Serum every day?
The 10% Vitamin C + E Ferulic Acid Serum may be used up to twice daily if your skin tolerates it well. However, the ideal frequency will depend on your skin's individual tolerance and the other active ingredients in your routine. If you are also using products such as retinoids, exfoliating acids, or other potent actives, you may wish to use the Vitamin C once daily or alternate its use to help minimize the potential for irritation or overstimulation.
Should I use the Vitamin C + E Ferulic Acid Serum in the morning or at night?
Vitamin C serum is most often recommended in the morning because its antioxidant properties help protect skin from environmental stressors encountered throughout the day. Always follow with a broad-spectrum sunscreen during daytime use.
Can I use the 10% Vitamin C + E Ferulic Acid Serum with Hyaluronic Acid?
Yes. Hyaluronic Acid pairs exceptionally well with Vitamin C because it helps hydrate the skin while Vitamin C brightens and provides antioxidant protection. Applying a hydrating serum after Vitamin C can help maintain moisture and support a healthy skin barrier.
Can I layer the 10% Vitamin C + E Ferulic Acid Serum with peptides?
Yes. Vitamin C and peptides can complement each other in a skincare routine. Many people use Vitamin C in the morning for antioxidant protection and peptides either afterward or in the evening to support smoother, firmer-looking skin.
Does Vitamin C help with dark spots?
Yes. Pure L-ascorbic acid is well known for helping improve the appearance of discoloration, sun spots, post-inflammatory hyperpigmentation, and uneven skin tone with consistent use over time.
Does Vitamin C help with fine lines and wrinkles?
Vitamin C supports healthy collagen production while protecting skin from oxidative stress, helping improve the appearance of fine lines and visible signs of aging over time.
How long does it take to see results from a Vitamin C serum?
Some users notice brighter-looking skin within a few weeks. Improvements in uneven tone, discoloration, and the appearance of fine lines generally become more noticeable after 8 to 12 weeks of consistent daily use.
Is the 10% Vitamin C + E Ferulic Acid Serum fragrance-free?
Yes. The Timeless Skin Care 10% Vitamin C + E Ferulic Acid Serum is formulated without added fragrance, making it suitable for those who prefer fragrance-free skincare.
Which Vitamin C serum is best for sensitive skin?
For sensitive skin, a Vitamin C serum formulated with 10% pure L-ascorbic acid, Vitamin E, and Ferulic Acid is often a great choice. The lower concentration is gentler on the skin while still delivering antioxidant protection, brightening benefits, and support for a more even-looking complexion.
Should I refrigerate Vitamin C serum?
Yes. Pure L-ascorbic acid is sensitive to heat, light, and air. Refrigerating your Vitamin C serum after opening helps preserve its freshness, maintain its potency, and slow oxidation. A fresh Vitamin C serum should appear clear to pale yellow. If it becomes dark orange or brown, it has likely oxidized and should be replaced.
Does Vitamin C fade acne scars?
Vitamin C can help improve the appearance of post-acne marks and post-inflammatory hyperpigmentation by promoting a more even skin tone. While it won't change the texture of indented acne scars, consistent use can visibly reduce discoloration and leave skin looking brighter over time.
Can Vitamin C brighten dull skin?
Yes. Vitamin C is one of the most effective skincare ingredients for brightening dull-looking skin. It helps reduce the appearance of discoloration, supports healthy skin renewal, and promotes a more radiant, even-toned complexion with regular use.
Can you use Vitamin C and Hyaluronic Acid together?
Yes. Vitamin C and Hyaluronic Acid are complementary ingredients that work well together. Vitamin C helps brighten skin and protect against environmental damage, while Hyaluronic Acid attracts moisture to help keep skin hydrated, plump, and comfortable. Many people apply Vitamin C first, followed by a Hyaluronic Acid serum.
Why combine Vitamin E with Vitamin C?
Vitamin E and Vitamin C work synergistically to provide enhanced antioxidant protection. Vitamin E supports the skin's moisture barrier, while Vitamin C helps brighten skin and defend against free radicals. Together with Ferulic Acid, these ingredients create a highly effective antioxidant blend that helps protect skin and improve overall skin tone.

Incredible Performance
I absolutely love this product. This vitamin C is packed with incredible ingredients, I am so thankful there is a product at this price point that packs such a punch and has such efficacy. My skin radiates and glows. I have been using this vitamin C product now for about a year and my skin has never looked better. I love the natural glow it gives me - this picture is not the best but it is natural, after my early morning weekend cleanse and application. Simply glowing.

Love at first drop!
I didn’t realize just how dry my face and neck had become until I started using this serum. After only a few days of using the 10% Vitamin C + E Ferulic Acid Serum, my skin felt noticeably smoother and silkier.
It absorbs well, layers nicely under my moisturizer, and has really helped improve the overall texture of my skin. My face and neck feel more hydrated, soft, and refreshed, and my skin looks healthier already.
I’m very impressed with the results so far and look forward to seeing continued improvements with regular use.
