If there’s one product that transforms dull, tired skin into a visibly radiant complexion, this is it Vitamin C serum. Loved by dermatologists and leading facialists alike, this powerful antioxidant brightens, firms and protects your skin from everyday environmental stressors.
But time matters. Even the best formula can lose potency if applied at the wrong time. So, should you use your vitamin C serum in the morning, at night, or both?
Here’s what the experts — and Joanna Vargas herself — recommend, plus how it Rescue Vitamin C + Serum Squalane provides lasting shine.
Basic Takeaways
Morning: Protects against pollution, blue light and UV-related oxidative stress.
Night: Boosts collagen repair and renewal while you sleep.
Always with SPF: Vitamin C and sun protection are the ultimate defense duo.
Consistency wins: Regular use matters more than frequency.
The rescue serum difference: A stable vitamin C combined with squalane for maximum absorption and hydration.
1. Why time matters
Vitamin C is one of the most delicate ingredients in skin care — highly effective, but prone to oxidation when exposed to light and air. When used correctly, it becomes one of the most transformative tools for maintaining glowing, firm and supple skin.
Applying it at the right time ensures that it works with your skin’s natural rhythm—protects during the day and restores at night.
As Joanna Vargas explains:
“Timing your actives isn’t about rules—it’s about results. Vitamin C performs differently depending on what your skin needs at the time.”
2. Why the Morning App shines
Most beauticians and dermatologists agree: morning is the ideal time to apply vitamin C.
Throughout the day, your skin faces oxidative stress from sunlight, blue light and pollution. Vitamin C acts as a powerful antioxidant shield, neutralizing free radicals before they damage collagen or dull your complexion.
When you use Rescue Vitamin C + Serum Squalane in the morning, you:
Protection from environmental aggressors.
Prevent blurring and uneven tone.
Enhance natural luminosity for a radiant, makeup-ready finish.
Follow me a broad spectrum SPF 30 or higher — this duo forms your skin’s daily defense system.
3. Night Benefits
While morning application protects, evening use restores.
As you sleep, your skin enters the recovery phase. Applying vitamin C serum at night helps stimulate collagen production, calm inflammation and correct signs of daily stress.
THE Rescue serum is ideal for this because it combines a stable, oil-soluble form of vitamin C (ascorbyl tetraisopalmitate) with squalane derived from olivewhich nourishes and supports the skin barrier without clogging pores.
Used morning, night or both — it adapts beautifully to your skin’s natural cycles.
4. How to Layer for maximum results
The right layer enhances each active ingredient. Joanna Vargas suggests:
Clean: Start with a gentle cleanser like Vitamin C face wash for preparation and cleaning.
Apply serum: Dispense 2-3 drops of Rescue serum on clean, dry skin. Gently press onto face, neck and décolleté.
Hydration: Follow me Daily Moisturizing Cream to strengthen the skin barrier.
Protect: In the morning finish with SPF. At night, use one Moisturizing cream for the whole night for additional food.
Professional advice: After exfoliating acids, allow 5-10 minutes before applying vitamin C to allow your skin’s pH to balance.
5. The Joanna Vargas Rescue Serum Difference
What makes this serum unique is not just its luminous power – it’s the harmony between Vitamin C, squalane and elderberry extract:
Vitamin C (ascorbyl tetraisopalmitate): A solid oil-based formula that penetrates deeply to tighten and tone without irritation.
Squalane: A plant-based moisturizer that mimics the skin’s natural oils to lock in moisture and boost barrier strength.
Elderberry Extract: A botanical antioxidant that helps protect skin from oxidative damage.
Together, they deliver visible radiance while strengthening your skin from within.
As Joanna Vargas shares:
“We designed this serum to deliver results without irritation. Squalane naturally stabilizes vitamin C, so every drop feels clean, powerful, and plant-energized.”
6. Consistency is everything
Whether applied morning, night or both, consistent use is what transforms your skin over time. Expect:
A brighter, more even complexion.
Reduced discoloration and dark spots.
Softer, firmer, more hydrated skin.
