1. Not all Vitamin C serums are created equal, and using an oxidized or ineffective formula can actually harm your skin.

2. The ideal Vitamin C serum should have a concentration between 10–20%, a pH of 4–6, and be packaged in an opaque, airless container to maintain potency.

3. Look for formulas that contain supporting ingredients like glutathione, ferulic acid, and hyaluronic acid to enhance the effectiveness of Vitamin C.

Let’s face it, the world of skincare can be overwhelming, and Vitamin C serums are no exception. With countless options on the market, it’s easy to get caught up in the hype and end up with a product that may not deliver the promised results — or worse, cause harm to your skin. Today we’re going to shed some light on the surprising truth about Vitamin C serums.

Master Esthetician Christine Byer

As a practicing Master Esthetician, I’ve seen firsthand the power of Vitamin C in protecting the skin barrier, promoting collagen synthesis, and reducing hyperpigmentation. However, I’ve also witnessed the consequences of using oxidized or poorly formulated Vitamin C products. You see, Vitamin C is one of the most volatile skincare ingredients, and if it’s not properly protected from air, light, and temperature fluctuations, it can lose its potency and even contribute to free radical damage — the very thing it’s supposed to combat.

The Ideal Vitamin C Formula

To ensure you’re getting the most out of your Vitamin C serum, it’s crucial to understand the ideal formulation. First and foremost, the concentration should be between 10–20%. Anything less may not provide the desired benefits, while higher concentrations can lead to skin irritation. Additionally, the pH level should be around 4 for optimal penetration into the skin, although those with sensitive skin may prefer a slightly higher pH of 5–6.

But it doesn’t stop there. The packaging plays a critical role in maintaining the serum’s potency. Look for opaque, airless containers that limit exposure to light and air, ensuring the ingredients remain stable from the first to the last drop.

Dr esthe serums

For Sensitive Skin

Navigating skincare can be challenging if you have sensitive skin. The Dr. esthe Vita-C Radiance serum is a game-changer. With a slightly higher pH and additional forms of Vitamin C like Sodium Ascorbyl Phosphate and Magnesium Ascorbyl Phosphate, it’s a gentler option that’s still highly effective. This formula also contains nourishing botanical extracts to soothe and calm easily-irritated complexions. Moreover, it boasts a vitamin complex comprising B5, B3, C, and E, delivering a potent brightening effect that targets dark spots, acne scars, pigmentation, and sun spots.

Frequently Asked Questions

Q: Can I Use Vitamin C Serum with Other Active Ingredients Like Retinol or AHAs?

Yes, you can absolutely use Vitamin C in conjunction with other active ingredients, but it’s best to apply them at different times of the day. For example, use your Vitamin C serum in the morning and your retinol or AHA product at night.

Q: How Long Does it Typically Take to See Results From Using a Vitamin C Serum?

While some people may notice a brighter, more even complexion within a few weeks, the full benefits of Vitamin C, such as increased collagen production and reduced hyperpigmentation, can take several months of consistent use.

Q: Can Vitamin C Serums Cause Photosensitivity?

While Vitamin C itself doesn’t cause photosensitivity, some formulations may contain ingredients that can make your skin more sensitive to sunlight. It’s always best to apply a broad-spectrum sunscreen after using your Vitamin C serum.

Make Vitamin C Your Daily Ritual

Incorporating Vitamin C serum into your daily skincare routine is a proactive step towards achieving healthy, radiant skin that stands the test of time. By investing in a high-quality Vitamin C serum like CBE Botanicals Triple C+ Gold, you’re not only safeguarding your skin against environmental stressors but also actively promoting collagen synthesis and maintaining a youthful complexion.
