FAQs
What is the shelf life of the Timeless Vitamin C + E Ferulic Acid Serum?
For best results, use your Vitamin C + E Ferulic Acid Serum soon after receiving it and within 3–6 months of opening, when it is freshest. Vitamin C can naturally oxidize over time. Store the serum in a cool, dark place; refrigeration is recommended to help slow oxidation and maintain freshness.
What is the texture of the Timeless 20% Vitamin C + E Ferulic Acid Serum? Is it watery or thick?
This Vitamin C serum has a lightweight, water-like texture. We intentionally formulate it this way so it absorbs quickly and layers easily under moisturizer, sunscreen, and makeup. The thin consistency also helps the serum spread evenly across the skin without feeling heavy or sticky.
What is the pH level of the Timeless 20% Vitamin C + E Ferulic Acid Serum?
The pH level of our 20% Vitamin C + E Ferulic Acid Serum is 2.4. This low pH helps support the stability and performance of L-Ascorbic Acid (pure Vitamin C) in the formula.
Can I travel with the Timeless 20% Vitamin C + E Ferulic Acid Serum if I normally keep it refrigerated?
Yes. If removed from the refrigerator while traveling, the serum can be kept at room temperature for normal use. Store away from heat, light, and humidity. For travel, our 20% Vitamin C + E Ferulic Acid pouches are a convenient option. Once home, we recommend returning the serum to the refrigerator.
Does the Timeless 20% Vitamin C + E Ferulic Acid Serum help improve uneven skin texture?
Yes. With consistent use, the 20% Vitamin C + E Ferulic Acid Serum can help improve the look of uneven skin texture by supporting a smoother, more refined-looking complexion. Vitamin C also provides antioxidant support, which helps improve overall skin tone and radiance over time.
Is the Timeless 20% Vitamin C + E Ferulic Acid Serum safe to use during pregnancy?
Vitamin C is widely considered a pregnancy-safe skincare ingredient. However, pregnancy and postpartum skin can be more sensitive due to hormonal changes. If you’re pregnant or nursing, we recommend patch testing first and checking with your healthcare provider before adding any new skincare products to your routine.
How long does the Timeless 20% Vitamin C + E Ferulic Acid Serum last with daily morning use?
With daily morning use, one 1 oz bottle typically lasts about 1 month, depending on how much you apply.
For best results, we recommend using your Vitamin C serum while it is freshest, ideally within 3 to 6 months of opening. Vitamin C can naturally oxidize over time, especially when exposed to heat, light, and air.
To help extend the shelf life, store your serum in a cool, dark place, and refrigeration is recommended to slow oxidation. When stored properly, the serum may last up to 1 year from the manufacturing date.
Will the Timeless 20% Vitamin C + E Ferulic Acid Serum be affected by heat during shipping?
Short periods of heat during shipping typically will not damage the serum. Vitamin C formulas are most likely to degrade from extended heat exposure or long-term direct sunlight over time.
If your order is delivered during extreme temperatures, we recommend placing the serum in the refrigerator upon arrival to help preserve freshness and slow oxidation. If you notice any damage, leakage, or a significant change in the product, please contact our support team at support@timelessha.com
so we can help.
Is the Timeless 20% Vitamin C + E Ferulic Acid Serum water-based?
Yes. Our 20% Vitamin C + E Ferulic Acid Serum is water-based, like all Timeless Skin Care products. This lightweight formula absorbs quickly and layers easily with the rest of your skincare routine.
Can I use the Timeless 20% Vitamin C + E Ferulic Acid Serum under my eyes?
We do not recommend applying our 20% Vitamin C + E Ferulic Acid Serum directly under the eyes. Because it is a high-strength Vitamin C formula, it may be too strong for the delicate under-eye area and could cause irritation.
For the under-eye area, we recommend using our Hyaluronic Acid + Vitamin C Serum, which contains a gentler 5% Vitamin C concentration and is better suited for sensitive skin.
Can I use the Timeless 20% Vitamin C + E Ferulic Acid Serum with retinoids?
We do not recommend using the 20% Vitamin C + E Ferulic Acid Serum in the same routine as retinoids. Because both are potent active ingredients, using them together may increase dryness or irritation for some skin types.
For best results, use Vitamin C in your morning routine and retinoids in your evening routine.
Can I use the Timeless Matrixyl Synthe’6 Multi-Peptide Serum with the 20% Vitamin C + E Ferulic Acid Serum? Which one goes first?
We do not recommend using the Matrixyl Synthe’6 Multi-Peptide Serum and the 20% Vitamin C + E Ferulic Acid Serum in the same routine. Since both are active formulas, using them separately can help reduce the chance of irritation and support the best performance of each product.
For best results, use the 20% Vitamin C serum in the morning, followed by moisturizer and SPF, and use Matrixyl Synthe’6 in the evening.
If the Timeless 20% Vitamin C + E Ferulic Acid Serum gets heated during shipping, is it still safe to use?
In most cases, yes. Short periods of heat during shipping typically won’t affect the serum. The formula would need to be exposed to extended heat or long-term direct sunlight for the ingredients to significantly degrade.
If your order arrives during extreme temperatures, we recommend placing the serum in the refrigerator upon receipt to help preserve freshness and slow oxidation. If you notice any leakage, damage, or a significant change in the product, please contact us at support@timelessha.com
so we can assist you.
Can I use the Timeless 20% Vitamin C + E Ferulic Acid Serum morning and night?
Because this is a high-strength 20% Vitamin C serum, we do not recommend using it twice daily. For most skin types, once per day is enough for effective brightening and antioxidant support.
For best results, use it in your morning routine, followed by moisturizer and SPF.
Should I apply the Timeless 20% Vitamin C + E Ferulic Acid Serum to damp or dry skin?
We recommend applying the serum to clean, dry skin. After cleansing, gently pat your face dry, then apply a few drops of Vitamin C to the face and neck. Allow it to absorb fully before applying moisturizer and SPF.
If you use toner, let it fully set before applying the serum.
Are there any skincare ingredients I shouldn’t use with the Timeless 20% Vitamin C + E Ferulic Acid Serum?
Because this is a high-strength Vitamin C formula, we recommend avoiding using it in the same routine as other highly active or stimulating ingredients, such as:
AHA/BHA exfoliating acids (glycolic acid, lactic acid, salicylic acid)
Vitamin A / retinoids (retinol, tretinoin, adapalene)
To help minimize irritation, use Vitamin C in the morning, and use exfoliants or retinoids in your evening routine instead.
Can I use the Timeless 20% Vitamin C + E Ferulic Acid Serum in the morning?
Yes. We recommend using the 20% Vitamin C + E Ferulic Acid Serum in your morning skincare routine for antioxidant support and brighter-looking skin. Follow with moisturizer and SPF.
How much Ferulic Acid is in the Timeless 20% Vitamin C + E Ferulic Acid Serum?
Our 20% Vitamin C + E Ferulic Acid Serum contains 1% Ferulic Acid.
Is the Timeless packaging curbside recyclable?
Some Timeless containers can be recycled curbside, while others are best recycled through TerraCycle depending on the material. For the most accurate recycling instructions by product and packaging type, please visit our Sustainability page, which includes details and a link to TerraCycle.
Does the Timeless 20% Vitamin C + E Ferulic Acid Serum contain any oil-based ingredients, or is it completely water-based?
The 20% Vitamin C + E Ferulic Acid Serum is water-based and does not contain oil-based ingredients. This lightweight formula absorbs quickly and layers easily in your skincare routine.
A full ingredient list is available on the product page.
Can I layer the Timeless 20% Vitamin C + E Ferulic Acid Serum with the Coenzyme Q10 + Peptides Serum?
Yes. The 20% Vitamin C + E Ferulic Acid Serum can be layered with our Coenzyme Q10 + Peptides Serum. For best results, apply Vitamin C first, then follow with Coenzyme Q10 + Peptides.
As a general rule, apply products from thinnest to thickest.
How do I apply the Timeless 20% Vitamin C + E Ferulic Acid Serum?
Apply 1–2 pumps to clean, dry skin on the face and neck. Allow the serum to fully absorb before layering moisturizer or other products. For daytime use, always finish with SPF.
How should I store the Timeless 20% Vitamin C + E Ferulic Acid Serum, and how long does it last?
For best results, we recommend storing your Vitamin C serum in the refrigerator to help preserve freshness and slow oxidation. For optimal performance, use within 3–6 months of opening.
If you notice a significant change in color or scent, the serum may be oxidizing and it may be time to replace it.
Will the Timeless 20% Vitamin C + E Ferulic Acid Serum irritate my skin?
Because this is a high-strength 20% Vitamin C serum, some users, especially those with sensitive skin, may experience mild tingling when first applying it. We recommend patch testing before full use and introducing it gradually (every other day at first).
If you experience persistent redness, burning, or irritation, discontinue use.
Can I use sunscreen with the Timeless 20% Vitamin C + E Ferulic Acid Serum?
Yes. We recommend using the 20% Vitamin C + E Ferulic Acid Serum in your morning routine, and always following with a broad-spectrum SPF 30+. Vitamin C provides antioxidant support, and sunscreen helps protect skin from UV damage and discoloration.
I've been reviewing many products for a Vitamin C serum to use in the morning. This is actually my first time to start using this on my face at my age (50's). Have been using this for a few weeks so far and have had no issues, and my face feels great! Great product and has all the ingredients that I was looking for.

I didn't receive my product; however, they responded promptly and sent me another one. The product is great! I wasn't the only one to notice the change right after starting to use it; my husband asked me about my skincare routine because my skin looked great. Now, we are using it together.
