Make sure to mix it with your moisturizer when applying.

After reading reviews mentioning a stinging sensation, I've been mixing it with my moisturizer from the start to avoid any irritation.

I felt like my complexion brightened up a bit. I used it every morning and evening for a week.

비타민C 91 인텐시브 세럼

Extremely tingling sensation. For someone with redness-prone skin, it feels like my face is about to explode and there's a burning sensation as if I've been scalded

I'm not sure I'm not sure I'm not sure I'm not sure I'm not sure I'm not sure I'm not sure I'm not sure I'm not sure I'm not sure I'm not sure I'm not sure

Unbelievable! They clearly marked the expiration date as November 10, 2023, but when I opened the lid, it was already spoiled. What a joke! And no, I hadn't opened it before - it was brand new. The moment I unsealed it, there was a 'poof' sound, and the product inside was completely oxidized and blackened. Don't buy this, folks. Just go for IOPE's 50,000 won Vitamin C serum instead. This is why people trust big companies... I know Vitamin C is unstable and sensitive to oxygen, but come on! This is ridiculous. Why even bother putting an expiration date if it's going to be like this?

Absolutely nothing good to say. It's ridiculously overpriced. Don't waste your money on unknown brands. Stick with well-established companies like IOPE. Their products are actually more affordable.

The user experience is disappointing... It causes a tingling sensation and just doesn't suit my skin.

I appreciate the high vitamin content. It's also reassuring that this product has received the German Dermatest certification.

Pro tips:

• After cleansing, tone your skin, then apply 3-4 drops of the serum
• Follow up with a vitamin or moisturizing cream for best results
• When going out after use, always apply sunscreen with SPF 15 or higher
• Avoid using immediately after exfoliation, peeling, laser treatments, shaving, or on eye area, mouth area, or wounds

Caution:

• If spilled on clothes, clean immediately to prevent staining

It contains two out of twenty cautionary ingredients and comes with a hefty price tag.

Dr. Erdem's Vitamin C 91 Intensive Serum boasts:

• An 'Excellent' grade from German Dermatest
• Free from harmful ingredients and non-irritating in skin sensitivity tests

• Vitamin content 200 times that of apples and 5 times that of lemons

Those with super sensitive skin may experience tingling or redness as it might cause irritation!

Review of Dr. Erdem Vitamin C 91 Intensive Serum

I've always been interested in Vitamin C serums due to my skin becoming dull from sun exposure and stress.

The Vitamin C serum I used before was a water-based ampoule that had an unpleasant scent and felt uncomfortable on my skin.

This product, however, has a banana milk-like color and is a highly concentrated essence. It has a subtle, pleasant fragrance, and I was satisfied that I could use it comfortably from the first application!

I pumped it twice on each cheek, and it absorbed quickly into my skin without leaving it dry. As time passed, I felt my complexion becoming clearer~

With 35% pure vitamin content, I think this product has great potential for amazing results with consistent use!

Since this product contains pure vitamin C, I only used it in my evening routine. If you want to incorporate it into your morning skincare, remember that sunscreen is absolutely essential!

Given the high concentration of pure vitamin C, you might experience a slight tingling sensation or redness at first. If you're new to it, try mixing it with your regular moisturizer or start with a small amount and gradually increase as your skin adjusts.

The Vitamin C91 Intensive Serum is a game-changer! With over 35% pure vitamin C, this rich formula packs a punch. As soon as you open it, a burst of fresh citrusy scent fills the air! I've tried various vitamin C products, but this one truly stands out. The morning after using it, my skin felt noticeably softer, and my makeup went on like a dream! After just a week of use, I went out without makeup, and someone commented on how radiant I looked!
