Compare two stable vitamin C derivatives from The Ordinary: oil-based Ascorbyl Tetraisopalmitate 20% and water-based Ascorbyl Glucoside 12%. Find out which brightening serum fits your skin type and routine.
Quick answer
Choose Ascorbyl Tetraisopalmitate Solution 20% in Vitamin F if you prefer an oil-based vitamin C that hydrates while brightening. Choose Ascorbyl Glucoside Solution 12% if you want a water-based, daily brightening serum for a more even skin tone.
Oil vs. water base: why it matters
The base of a vitamin C derivative affects how it feels on your skin and when you apply it. Oil-based formulas layer differently than water-based ones, especially under moisturizer or sunscreen.
Ascorbyl Tetraisopalmitate 20% comes in a vitamin F (linoleic acid) oil base, making it a natural fit for dry or normal skin types. Ascorbyl Glucoside 12% is water-based, so it absorbs quickly and works well for oily or combination skin.
Concentration and stability
Both derivatives are stable forms of vitamin C, meaning they are less likely to oxidize quickly compared to pure L-ascorbic acid. This makes them easier to store and use daily without worrying about rapid degradation.
Ascorbyl Tetraisopalmitate is used at 20% concentration, while Ascorbyl Glucoside is at 12%. Higher percentage does not automatically mean better results—the molecule size and skin penetration also play a role. The 20% oil-based formula is designed to deliver a potent dose in a hydrating base.
Trade-offs at a glance
- Texture preference: Ascorbyl Tetraisopalmitate is oil-based; Ascorbyl Glucoside is water-based. Choose the texture that fits your skin type and routine.
- Hydration vs. lightweight feel: The 20% oil formula hydrates; the 12% water formula feels lighter.
- Daily use: Both are stable enough for daily application, but the water-based option may layer more easily under makeup. Test each in your AM routine to see which layers best.
