10% Waterless Vitamin C Serum

Vitamin C's biggest weakness is water — it destabilises the active before you finish the bottle. Farmacy 10% Waterless Vitamin C Serum removes the water entirely, keeping 10% L-ascorbic acid potent to the last drop while it brightens, firms and fades the look of dark spots.

What it actually does

• Brightens with pure vitamin C. 10% L-ascorbic acid — the purest form of vitamin C — visibly evens tone and tightens the look of skin, kept stable by the waterless base.
• Doubles down on dark spots. 1% alpha-arbutin and ferulic acid target hyperpigmentation and, per Farmacy, amplify what the vitamin C is doing.
• Hydrates despite being water-free. Upcycled tangerine peel and sugar beet boost moisture and radiance without irritation.
• Feels silky, not oily. The base is propanediol — not an oil, but it dries down to a smooth, silky finish. The formula is both water-free and oil-free.
• Brand-reported clinicals. In Farmacy's 8-week study of 33 participants, users reported visibly brighter skin after a single use, a 16x improvement in the size and intensity of dark spots over 4–8 weeks, and that the serum stayed gentle at twice-daily use. Brand-run study — results vary.
• Vegan, gluten-free, cruelty-free, in fully recyclable packaging.

How to use

1. Apply to clean skin, morning and night.
2. Layer moisturiser on top.
3. In the morning, finish with SPF — essential when treating dark spots.

Questions

Why does "waterless" matter?

L-ascorbic acid degrades in water-based formulas. By removing water, Farmacy keeps the vitamin C at maximum stability and potency for the life of the bottle instead of just the first few weeks.

Is it an oil? It feels like one.

No — the base is propanediol, which mimics an oil's slip but isn't one. The formula is oil-free as well as water-free, and dries to a silky-smooth finish.

Can I use it twice a day?

Yes — the directions say morning and night, and Farmacy's study participants reported it stayed gentle with twice-daily use.
