Why You'll Love It:

• Instant Radiance: Visibly revives dull, tired-looking skin for that effortless, all-day glow.

• The Perfect Balance: We took the clinically proven trio—20% Vitamin C, Vitamin E, and Ferulic Acid—and perfected the texture so it’s potent, yet gentle on your barrier.

• Fades Dark Spots: Works consistently over time to gently blur the look of hyperpigmentation and uneven tone.

• Your Daily Armor: Acts as an invisible, breathable shield against city air and screen time, keeping your skin healthy and resilient.

The Vibe

Between screen time, city air, and a busy schedule, skin can easily lose its natural bounce and brightness. We created C+E+Ferulic to be the ultimate, zero-fuss morning step that does it all: brightens, protects, and restores your natural glow.

The Cyrène Difference

Formulated by our founder and Cosmetic Chemist, this isn't just another sticky Vitamin C. We paired 10% pure Ascorbic Acid with 10% 3-O-Ethyl Ascorbic Acid (a highly stable, deeper-penetrating form). By adding Ferulic Acid and Vitamin E, we ensured the formula stays potent to the very last drop, delivering a beautiful, lightweight finish that sits perfectly under makeup.

Inside The Formula

• 20% Vitamin C Complex: A high-performance dual blend. 10% pure Ascorbic Acid for immediate surface radiance, plus 10% Ethylated L-Ascorbic Acid to visibly smooth fine lines and fade stubborn spots.

• 1% Tocopherol (Vitamin E): A deeply nourishing lipid-soluble antioxidant that replenishes your skin’s barrier and doubles the protective power of Vitamin C.

• 0.5% Ferulic Acid: A plant-derived super-ingredient that stabilizes the formula, ensuring maximum efficacy and targeted defense against daily stress.

• Hyaluronic Acid: Your skin's moisture magnet. Instantly plumps and hydrates, leaving the skin feeling soft and bouncy, never tight.

Your Morning Ritual

When to use: ONLY in the AM (Morning).

1. Cleanse: Refresh your skin with our Enzyme Cleansing Gel. Pat dry.

2. Treat: Apply 4-5 drops of C+E+Ferulic Serum to a completely dry face, neck, and chest. Gently press and sweep into the skin. (A slight tingle is normal for such a highly active formula).

3. Moisturize: Lock in the glow with your favorite Cyrène cream, like our Skin Rescue Moisturiser.

4. Protect: Finish with our Invisible Physical Sunscreen SPF 50. Vitamin C and SPF are the ultimate morning duo for healthy skin.

The FAQs 

Q: Does this have that typical "hot dog water" Vitamin C scent? A: We know exactly what you mean! Traditional high-dose Vitamin C serums are infamous for their metallic scent. Thanks to our advanced stabilization and the inclusion of Ethylated Ascorbic Acid, our formula minimizes that typical odor while giving you top-tier clinical results.

Q: Is it suitable for breakout-prone skin? A: While C+E+Ferulic is universally loved, 20% is a very potent concentration. If your skin is currently experiencing active breakouts, we recommend our Silymarin + CF serum—it’s specifically balanced with Salicylic Acid to clarify pores while providing that same antioxidant glow.

Q: Will it feel sticky under my makeup? A: Not at all. It’s formulated to absorb beautifully and quickly, leaving a smooth, radiant base that plays perfectly with your daily moisturizer, SPF, and foundation.
