Why 3-O-Ethyl Ascorbic Acid? +
Most vitamin C serums use L-Ascorbic Acid, which is highly effective but notoriously unstable — it oxidizes within weeks, turns orange or brown, and loses potency before you finish the bottle. We use 20% 3-O-Ethyl Ascorbic Acid, a next-generation derivative that's water and oil soluble, penetrates deeper into the skin, stays stable from first drop to last, and delivers the same brightening and antioxidant benefits without the sting or pH issues.
Ingredients & Allergies +
Active ingredients: 20% 3-O-Ethyl Ascorbic Acid, Ferulic Acid, Vitamin E (Tocopherol), Hyaluronic Acid, Niacinamide.
Free from: synthetic fragrance, parabens, phthalates, sulfates, mineral oil, formaldehyde-releasers, and synthetic dyes.
Allergies: Always patch test before first use. The formula is fragrance-free and well-tolerated, but if you have known sensitivities, review the full INCI list on the bottle.

Step 3: Press gently into skin, avoiding the eye area. Wait 60 seconds for absorption.

When Will I See Results? +
Most customers report a visible glow within 7–10 days of consistent morning use. Brightening of dark spots and improvement in skin tone typically shows around weeks 4–8. For long-term anti-aging benefits, daily use combined with sunscreen delivers the strongest results.
Pregnancy & Sensitive Skin +
3-O-Ethyl Ascorbic Acid is generally considered safe during pregnancy and breastfeeding — it's a vitamin C derivative, not a retinoid. The fragrance-free, gentle formula is also well-tolerated by sensitive skin. As always, consult your healthcare provider if you have specific concerns.
Size & Packaging +
30 mL / 1 fl oz frosted glass dropper bottle. The amber-tinted glass and dropper design protect the formula from light degradation and contamination. With morning use of 3–4 drops, one bottle lasts approximately 8–10 weeks.

Trusted by Canadian skincare enthusiasts
★★★★★
"Brightens without the burn"
Every other vitamin C serum I've tried left my face stinging. This one absorbs cleanly, doesn't tingle, and my skin actually looks brighter after about two weeks.
★★★★★
"Dark spots fading after years"
Sun spots from summers past have been bothering me forever. After about 6 weeks of consistent use, they've genuinely lightened. Wish I'd started years ago.
★★★★★
"Doesn't go orange in the bottle"
I'm halfway through my first bottle and the formula still looks and smells exactly like day one. Past serums I've used would oxidize within weeks.
★★★★★
"Layers beautifully under SPF"
Lightweight, no pilling, no weird residue. My makeup goes on smoother since I added this to my morning routine.
★★★★★
"My skin glows now"
Friends keep asking what I'm doing differently. It's this. The glow is real and I'm not going back to my old routine.
★★★★★
"Perfect with the night cream"
I bought this with the Bakuchiol Night Cream as a duo. Brightening in the AM, renewal at night — my skin has never looked this even-toned. Worth it.
Any Last Questions?
You asked. We answered.
Can I use this with the Bakuchiol Night Cream? +
Yes — they're designed to layer. Use this Vitamin C Serum in the morning under SPF for brightening and antioxidant defense, and the Bakuchiol Peptide Night Cream as your last evening step for overnight renewal.
Can I use this with retinol or AHAs/BHAs? +
Yes, but separate them in your routine. Use Vitamin C in the morning and your retinol or exfoliating acids at night to avoid layering active ingredients that may cancel each other out or cause irritation.
