Among those struggling with skin trouble, some find that changing their skincare doesn’t improve things much, and that taking supplements doesn’t produce noticeable results either. Amid this, one treatment that’s been getting attention lately is the “high-dose vitamin C IV drip.”
This time, I actually underwent “high-dose vitamin C 12.5g IV drips once a week for 4 weeks” myself, and I’ll report in detail on the changes I experienced until my skin trouble calmed down!

A high-dose vitamin C IV drip is a treatment that administers vitamin C directly into the bloodstream at concentrations far higher than can be achieved through regular oral intake. Vitamin C has powerful antioxidant properties and is expected to offer health benefits such as improved skin, boosted immunity, and reduced stress.
Vitamin C obtained from a typical diet or supplements is absorbed through the intestines, so once it exceeds a certain amount, it’s excreted. With an IV drip, however, you can raise the vitamin C concentration in your blood all at once, absorbing the vitamin fully without waste and approaching beauty and health more effectively.
【Treatment Details】
⚫︎IV Contents: High-dose vitamin C 12.5g, domestically produced and preservative-free
⚫︎Regular Care: One packet per day (1000mg vitamin C) of Clinience Liposomal Vitamin C on days without an IV drip
⚫︎Frequency: Once a week × 4 times (over 1 month)
⚫︎Goal: Improving skin trouble, reducing redness and acne, resolving dullness
【Expected Effects】
⚫︎Anti-inflammatory action to calm acne and skin trouble
⚫︎Removing free radicals and normalizing skin cell turnover
⚫︎Promoting collagen production for firmer skin
⚫︎Boosting immunity to reduce skin trouble
【Treatment Process】
⚫︎Had a consultation to confirm suitability for the vitamin C IV drip
⚫︎Ate and hydrated beforehand
⚫︎Received the drip over about 30 minutes
【Impressions During Treatment】
Once the drip started, I felt a slightly cold sensation in my arm along with a mild, dull ache — tolerable. Partway through I felt a bit sleepy, and I was able to receive the treatment in a relaxed state.
【Changes After Treatment】
⚫︎I didn’t feel any immediate change in my skin, but the next morning my skin tone seemed a little brighter
⚫︎I had been concerned about dryness, but the next day my skin felt more hydrated than usual
At this point there wasn’t a major change, but my skin condition felt a little more settled, and I looked forward to seeing further changes.
About a week had passed since the first drip. At this point my skin trouble hadn’t completely cleared up, but I noticed that new acne was less likely to form.
【Changes After Treatment】
⚫︎My skin texture became more even, and my makeup went on better
⚫︎The redness of my acne calmed down a bit
⚫︎I felt like the dark circles under my eyes lessened
High-dose vitamin C IV drips are also said to improve blood flow and complexion due to their strong antioxidant effect. In fact, after finishing my second session, I noticed a bit of clarity, as if the dullness had lifted.
By the third session, I could feel even more of a change. Having gotten used to the vein discomfort, I had the drip speed increased, and it finished in 20 minutes!
【Changes After Treatment】
⚫︎Redness on my cheeks and jawline clearly decreased
⚫︎Small pimples became less likely to form, and skin roughness lessened
⚫︎I stopped noticing dryness by the evening
Also, since vitamin C promotes collagen production, I felt my skin’s firmness and elasticity gradually improving too. Around this point, people started telling me more often that my skin looked good.
By the fourth and final drip, my skin condition improved even further, and compared to before treatment I could clearly feel that my skin trouble had calmed down. The bumpy, rough feeling and the sense of clogged acne when touching my skin were gone!!

【Changes After Treatment】
⚫︎Red acne marks faded quite a bit
⚫︎Overall skin tone became more even, with more clarity
⚫︎Pores tightened, and makeup stayed on better
In particular, the redness that had been on my cheeks became barely noticeable, and my skin overall looked calmer.
✔ Skin redness and inflammation calmed down, and acne became less likely to form
✔ Clarity improved and dullness cleared up
✔ Moisture retention improved, reducing dryness-related skin trouble
✔ Pores tightened and makeup went on better
✔ Overall physical condition improved and I got tired less easily
✖ Cost per session is relatively high (¥10,800 for 12.5g)
✖ Treatment takes about 30 minutes, requiring some schedule coordination
✖ Bruising at the injection site on the arm occurs rarely.
Through this month of treatment, I was able to feel real improvement in my skin trouble and a boost in clarity, so I feel it’s a treatment I can recommend to people struggling with skin trouble. That said, since maintaining the effect requires ongoing care, receiving it regularly is ideal.
If you’re concerned about skin trouble, considering a high-dose vitamin C IV drip in addition to your skincare and oral supplements is one option worth exploring.
