Tri Vita C is Dermaceutic's most concentrated vitamin C serum, combining three forms of vitamin C at 30% for intensive revitalisation. Use it in the evening as a course, typically over 3 months.

1. In the evening, cleanse your skin and pat dry.
2. Apply a few drops to the face and neck, avoiding the eye contour area.
3. Allow it to absorb, then follow with your moisturiser if needed.
4. In the morning, always apply a broad-spectrum SPF 50+ sunscreen.

Tips:
- Introduce it progressively: start with 2 to 3 evenings a week and build to nightly as your skin adjusts. A brief warming or tingling sensation on application is common with high-strength vitamin C.
- Do not combine with retinol or AHA exfoliating products (Foamers, TurnOver, Light Ceutic, Activ Retinol) in the same evening. Alternate nights if you use them.
- A 3-month course is recommended, and it can be repeated after a break.
- Patch test before first use, particularly if your skin is sensitive or reactive.
- Not recommended during pregnancy or breastfeeding, or for very reactive skin. Check with your GP if unsure.
- Pair the course with C25 Cream in the mornings afterwards to maintain the antioxidant habit year-round.
Key ingredients:
- L-Ascorbic Acid 15%: pure vitamin C for optimal antioxidant action against free radicals
- Ascorbyl Silanol 14.5%: a stabilised vitamin C that helps protect against the visible signs of photoageing
- Ascorbyl Ester 0.5%: an oil-soluble vitamin C that helps even the look of the complexion and boost radiance
- Vitamin E Ester: an antioxidant that works in synergy with vitamin C
- Ferulic Acid Ester: enhances the protective action of vitamins C and E

Skin showing fine lines, loss of firmness, dullness or uneven tone that wants an intensive vitamin C course. It is a strong serum, so it is best suited to resilient skin. Sensitive or reactive skin should start with C25 Cream instead.
Dermaceutic recommends evening use so the concentrated actives work without sun exposure, with a high SPF applied every morning. Evening use also makes it easy to keep it separated from your morning products.
Not in the same session. Alternate evenings: Tri Vita C some nights, your retinol or acid on others. Layering them together raises the chance of irritation without better results.
Brand studies over 20 to 60 days recorded a brighter, more even looking complexion and a visible softening of fine lines. Commit to the recommended 3-month course for the full effect.
