How to Apply

Unlock your skin's brightest potential

MORNING ONLY (most important):
1

Cleanse and pat dry completely

Vitamin C works best on completely dry skin. Wait 1 minute
after cleansing.

2

Apply 3-5 drops to entire face and neck

A little goes a long way. Distribute evenly across all areas—
this is a treatment for your whole face.

3

Let absorb for 1-2 minutes

Give it time to penetrate before adding other products. You
may feel slight tingling—normal!

4

Follow with moisturizer and SPF

CRITICAL: Vitamin C makes skin more sun-sensitive. SPF 30+
is mandatory.

💡 PRO TIPS FOR MAXIMUM RESULTS

  • Store in a cool, dark place—vitamin C degrades with light and heat
  • If serum turns brown/orange, it's oxidized—replace it
  • Start every other day if you have sensitive skin, build up to daily
  • Use within 3-6 months of opening for maximum potency
  • Consistent AM use = dramatically better results than sporadic use

SIZE: 1 fl oz (30 ml)

Frequently Asked Questions

Category

What type of vitamin C is in this serum?

L-ascorbic acid at 15%—the ONLY form of vitamin C with decades of research proving it penetrates skin and delivers results. Vitamin C derivatives (ascorbyl palmitate, magnesium ascorbyl phosphate, etc.) are gentler but FAR less effective. We use the gold standard.

Why does this tingle when I apply it?

L-ascorbic acid has a low pH (2.8-3.2) which is necessary for it to penetrate skin. This acidity causes temporary tingling in most people. It's completely normal and harmless. The tingling usually stops after 1-2 weeks as your skin adjusts. If it BURNS (not tingles), reduce frequency.

Can I use this with niacinamide? I heard they can't be mixed.

That's an OLD MYTH based on outdated research! Modern formulations of vitamin C and niacinamide work perfectly together. You can use them in the same routine. Apply vitamin C first (on dry skin), wait 1-2 minutes, then apply niacinamide serum.

Should I use this in the morning or evening?

Morning only. Vitamin C works best during the day because:

  1. It protects against daytime UV and pollution damage
  2. It boosts your SPF’s effectiveness
  3. Using it at night is wasted — your skin can’t use it while you’re sleeping.

Save your evening for retinol or other treatments.

Do I HAVE to use SPF with vitamin C?

YES. Absolutely non-negotiable. Vitamin C makes skin more sun-sensitive, and without SPF, you risk sun damage. Plus, vitamin C + SPF together provide 4x better UV protection than SPF alone. Use SPF 30+ every single morning, no exceptions.

My serum turned orange/brown. Can I still use it?

NO! When vitamin C oxidizes (turns dark orange or brown), it's no longer effective and can even irritate skin. Toss it and get a new bottle. To prevent oxidation: store in a cool, dark place (fridge is ideal), keep cap tightly closed, use within 3-6 months of opening.

Can I use this with retinol?

Not at the SAME TIME. Use vitamin C in the MORNING and retinol in the EVENING. Together (in different time slots), they're a powerful anti-aging duo: vitamin C boosts collagen and protects by day, retinol renews and repairs at night.

I'm breaking out since I started using this. Why?

This could be "purging"—vitamin C accelerates cell turnover, bringing existing congestion to the surface faster. TRUE PURGING happens in your usual breakout zones and clears within 2-4 weeks. If you're breaking out in NEW areas or it lasts longer, you may be experiencing irritation. Reduce frequency or discontinue.

Should I apply this to wet or dry skin?

DRY SKIN ONLY. Wait at least 1 minute after cleansing before applying. Vitamin C needs to be at a specific pH (2.8-3.2) to penetrate, and water dilutes that pH, making it ineffective. Dry skin = maximum results.

How long before I see results?

Immediate glow within 1 week. Visible brightening and tone evening within 3-4 weeks. Fine line reduction and firming within 6-8 weeks. Maximum collagen-boosting results at 12+ weeks. Consistency is critical—daily use delivers dramatic results.

Is this safe during pregnancy?

Topical vitamin C is generally considered safe during pregnancy, but we always recommend consulting your doctor before using any active ingredients while pregnant or nursing. Your doctor can make the best decision for your specific situation.

Why is vitamin C so expensive compared to other serums?

L-ascorbic acid is difficult to formulate—it's unstable, oxidizes easily, and requires specific pH and packaging. Quality vitamin C serums use pharmaceutical-grade ingredients, airless packaging, and careful formulation. You're paying for EFFECTIVENESS. Cheap vitamin C is usually ineffective or oxidized.

Can I use this if I have sensitive skin?

Vitamin C can be irritating for very sensitive skin, especially at 15% concentration.

If you have sensitive skin:

  1. Start every other morning for the first 2 weeks.
  2. Apply to damp skin instead of dry (less effective but gentler).
  3. Mix with moisturizer to buffer.
  4. Consider starting with a lower concentration (10%).

How should I store this to prevent oxidation?

Store in a cool, dark place. Fridge is ideal but not required. Keep cap tightly closed. Avoid exposing to direct light or heat. Use within 3-6 months of opening. If the serum turns dark orange or brown, it's oxidized—toss it.

Can I use this around my eyes?

Yes, but be cautious. The eye area is delicate and may be more sensitive to vitamin C's acidity. Gently pat a very small amount around the orbital bone (NOT on lids or too close to lash line). Avoid getting product IN the eyes. If it stings, avoid the eye area.

Is 15% too strong? Should I start with a lower concentration?

15% is clinical strength—powerful but well-tolerated by most skin types. If you're NEW to vitamin C or have sensitive skin, you can start with every other day and build up. But don't buy a weaker concentration—below 10% isn't effective enough to deliver real results.
