How and When to Use Neostrata 15% Vitamin C + PHA for Maximum Benefits
Vitamin C has earned its place as a must-have skincare ingredient, and when combined with PHA (polyhydroxy acid), it becomes even more powerful. Neostrata 15% Vitamin C + PHA is specially formulated to brighten, protect, and gently exfoliate the skin. But many people wonder: when is the best time to use it? Here’s a clear guide to help you incorporate it into your routine for optimal results.
Why Timing Matters
The effectiveness of any active skincare ingredient depends on how and when you apply it. Vitamin C works best when it penetrates clean, dry skin, while PHAs gently exfoliate without causing irritation. Correct timing ensures:
- Maximum absorption of Vitamin C.
- Enhanced brightening and collagen-stimulating effects.
- Reduced risk of irritation from other actives.
Best Time to Use Neostrata 15% Vitamin C + PHA
Morning Use
Using Vitamin C serum in the morning can give your skin a protective boost throughout the day:
- Antioxidant Defense: Vitamin C neutralizes free radicals caused by sun exposure and pollution.
- Brightening: Helps maintain an even, radiant skin tone from morning to evening.
How to Use in the Morning:
- Cleanse your skin.
- Apply 2–3 drops of Neostrata 15% Vitamin C + PHA on the face and neck.
- Follow with a moisturizer.
- Always finish with broad-spectrum sunscreen to protect your skin and maximize Vitamin C’s benefits.
Evening Use
Vitamin C + PHA can also be used in your nighttime routine for skin renewal:
- Cell Turnover Support: PHAs gently exfoliate, removing dead skin cells to allow Vitamin C to penetrate deeper.
- Repair & Regeneration: The skin repairs itself overnight, making nighttime application ideal for long-term brightening and texture improvement.
How to Use in the Evening:
- Cleanse your face thoroughly.
- Apply the serum evenly on dry skin.
- Follow with your preferred moisturizer to lock in hydration.
Tip: If you’re new to Vitamin C or exfoliating acids, start with once a day (morning or evening) and gradually increase to twice a day if your skin tolerates it.
The Bottom Line
Neostrata 15% Vitamin C + PHA is versatile enough for both morning and evening use. The key is to apply it consistently on clean skin, pair it with a moisturizer, and use sunscreen in the daytime. By using it at the right time, you can maximize its brightening, protective, and anti-aging benefits — giving your skin the glow it deserves.
