Summary
Timeless Skin Care's Hyaluronic Acid + Vitamin C Serum combines three proven actives in one step: 5% Vitamin C (Magnesium Ascorbyl Phosphate), 1% Matrixyl® 3000 peptides, and 1% Hyaluronic Acid. It hydrates, brightens, supports collagen, smooths fine lines, and helps even skin tone, and targets dehydrated skin and dullness. The formula is vegan, fragrance-free, paraben-free, sulfate-free, dye-free, and cruelty-free, made in small batches in the USA. In a 14-day third-party clinical trial of 20 participants ages 21–64, 100% agreed their skin felt more moisturized, brighter, and more even in tone. It costs $23.95 for 1 oz (a 4 oz size is also available) and is rated 4.8 out of 5 stars from 475 reviews.
Best for
- All skin types, including oily and sensitive skin
- Dehydrated skin and dullness that need daily hydration plus brightening
- Anyone wanting hydration, antioxidants, and peptide firming support in one serum instead of stacking several bottles
- Shoppers avoiding fragrance, dyes, parabens, and sulfates
- Not for use directly under the eyes—the page recommends products specifically formulated for the eye area instead
How it compares
Within the Timeless range, this serum uses 5% Vitamin C as Magnesium Ascorbyl Phosphate (MAP), a form suited to sensitive and oily skin, while the brand's 20% Vitamin C + E Ferulic Acid Serum delivers a higher concentration of L-ascorbic acid. Its distinguishing feature is the three-actives-in-one formula: Vitamin C, Matrixyl® 3000 peptides, and Hyaluronic Acid together, so one serum covers hydration, brightening, and collagen support. Like all Timeless serums, it is made in small batches in the USA without fragrance or fillers.

Using both together creates a balanced routine that targets hydration and radiance simultaneously.
