Cathy Doll Whitamin C Spot Serum 30ml

Most brightening serums ask you to take their word for it. This one was put through a 14-day instrumented clinical study on 23 women, twice-daily use on face and neck, with skin color measured by spectrocolorimeter at day 0, 7 and 14. The result: every single subject measured lighter skin at the spot zone by day 14, and the standard instrument measure of skin brightening (ITA°) improved +31% on average. Zero irritation was reported across the full study.

The vitamin C that does the work
The formula is built on Ethyl Ascorbic Acid, a stabilized vitamin C derivative that resists the oxidation that kills ordinary vitamin C in heat and light — a real advantage in a Gulf bathroom cabinet. Once absorbed, it converts to active vitamin C in the skin and slows tyrosinase, the enzyme that produces the melanin behind dark spots, acne marks and uneven tone.

Sealed until it reaches your skin
The serum uses vitamin C encapsulation: the active is protected inside the formula so it arrives at the skin potent instead of pre-oxidized in the bottle. That protection is why the serum can promise the same performance in week one and week ten.

The supporting cast
Arbutin and Kojic Dipalmitate — two classic spot-fading molecules — back up the vitamin C at signature levels, alongside radish, licorice, chamomile and Kakadu plum extracts. Hyaluron holds water in the skin while the actives work: 96% of study subjects said their skin felt more moisturized.

Texture and feel
An orange, water-light serum with a soft citrus scent. In testing, 100% of subjects agreed it applies easily, absorbs quickly, and leaves no greasy or sticky finish — so it layers cleanly under sunscreen in the morning and moisturizer at night.

- Clinically tested: 100% of 23 women measured lighter skin at the spot zone in 14 days
- Stabilized Ethyl Ascorbic Acid slows the enzyme that produces dark-spot pigment
- Vitamin C encapsulation keeps the active potent until it reaches the skin
- Arbutin and Kojic Dipalmitate support the brightening work
- Hyaluron hydrates while the actives work — no tight, treated feel
- Fast-absorbing dropper serum for AM & PM use, face and neck

✓ Evens skin tone: skin brightening angle (ITA°) improved +31% on average, measured by instrument
✓ Reduces the yellow, dull cast in skin — measured 3% lower in 14 days
✓ Vitamin C encapsulation protects potency from heat and light until the serum reaches your skin
✓ Arbutin and Kojic Dipalmitate back up the vitamin C at signature levels
✓ Hydrates with hyaluron — 96% of testers said skin felt more moisturized
✓ Absorbs fast with no greasy or sticky finish — 100% agreement in testing
✓ Gentle enough for twice-daily use: zero irritation reported across the full study

1. Twist open the cap and press the dropper to release a few drops onto your palm.
2. Gently pat onto areas of dullness and dark spots, or sweep across the whole face and neck until absorbed. Avoid the eye area.
3. Use morning and evening after cleansing.
4. In the morning, always follow with sunscreen. Unprotected sun is how dark spots start — the serum fades them, the SPF keeps them gone.
5. The clinical results were measured at day 7 and day 14 of twice-daily use. Consistency is the dose.
6. Caution: Stop using and seek medical treatment if any signs of abnormality appear.
