Can I use the Hyaluronic Acid + Vitamin C Serum under the eyes?

Review the ingredient list of the 20% Vitamin C + E Ferulic Acid Serum and consult your healthcare provider if needed. For external use on face and neck only. Avoid eyes and chest/nipple area. Discontinue if irritation occurs. Store in a cool, dry place away from sunlight.
What does Timeless Skin Care Hyaluronic Acid + Vitamin C Serum do?
Timeless Skin Care Hyaluronic Acid + Vitamin C Serum provides intense hydration by attracting and retaining moisture in the skin. Formulated with 1% pure Hyaluronic Acid (Sodium Hyaluronate), and Matrixyl® 3000 peptides, it helps plump the appearance of fine lines, improve skin softness, and support a healthy moisture barrier for smoother, more hydrated-looking skin. Hyaluronic acid is capable of binding significant amounts of water, making it one of skincare's most effective hydrating ingredients.
Should Hyaluronic Acid be applied to damp skin?
Yes. Applying Hyaluronic Acid + Vitamin C Serum to damp skin (not wet) to allow it to bind to available water and helps maximize hydration. After cleansing, lightly pat your face so it remains slightly damp before applying 2–3 drops of serum, then seal everything in with a moisturizer. Dermatologists commonly recommend this application method for best hydration results.
Can I use Hyaluronic Acid + Vitamin C Serum every day?
Absolutely. Hyaluronic Acid is a gentle, naturally occurring ingredient that is safe for daily use even twice daily. Because it is non-exfoliating and non-irritating, it's an excellent hydration step in both morning and nighttime skincare routines.
Can I use Hyaluronic Acid with Vitamin C?
Yes. Hyaluronic Acid pairs exceptionally well with Vitamin C. Vitamin C helps brighten skin and defend against environmental stressors, while Hyaluronic Acid replenishes moisture and Matrixyl® 3000 peptides helps skin feel softer and smoother. Using both together creates a balanced routine that targets hydration and radiance simultaneously.
Can Hyaluronic Acid help dry or dehydrated skin?
Yes. Hyaluronic Acid is considered one of the best ingredients for dehydrated skin because it attracts water to the skin's surface and helps improve long-lasting hydration. Regular use helps reduce dryness, flaking, and tightness while leaving skin feeling soft and comfortable.
Is Hyaluronic Acid + Vitamin C Serum fragrance-free?
Yes! Our Hyaluronic Acid + Vitamin C Serum with Matrixyl® 3000 peptides is fragrance-free and formulated without unnecessary fillers, making it a great option for those looking for a simple, gentle hydrating serum.
How long does it take to see results from Hyaluronic Acid?
Many people notice softer, more hydrated skin immediately after application. With consistent daily use over several weeks, skin often appears smoother, plumper, and more resilient as hydration levels improve.
I've been using Timeless for years but I don't know how I could've bypassed the Hyaluronic acid + Vit. C (along with Matrixyl 3000!) until now. I've begun trying to utilize serums/treatments that have multiple actives in them to pare down the amount of bottles on my counter, and hence, the number of products, and number of steps, there have been in my AM/PM skincare regimens. So while re-evaluating ALL the actives I want in my skincare, I'm now trying to get more actives together in one place. Thank you Timeless for providing simplified and excellent products.
