Reviews Summary
Customers say this night treatment helps reduce the appearance of blemishes by morning. Many reviews mention visible improvements after just one use, with redness and swelling noticeably diminishing overnight. The gel-like texture applies smoothly, though some note it can feel slightly sticky. While most find it effective for regular use, several suggest alternating it with other products in their routine. A few reviews mention it can be somewhat drying, recommending pairing with a good moisturizer. Most users appreciate how it helps manage breakouts when used consistently.

    On the fence a bit about this

    I don't feel like this helps with hormonal acne or blackheads, but for traditional pimples this works to clear up skin if used consistently. however after 2-3 nights of use it starts to irritate my skin, making it hard to be consistent with use. I actually use this on my body for chest/backne spots since i work out a lot and tend to breakout on those areas. Seems to work better for body than my face lol

    Outdated Acne Philosophy

    I guess I'll take some of the blame for not fully reading the product page before purchasing but when I got this home and read the usage instructions, I was extremely confused. You are instructed to use this at night instead of moisturizer. I'm sorry....what?! I rechecked the ingredient list to see if this treatment could substitute for moisturizer and it definitely shouldn't. The only hydrator it contains is glycerin, which is not enough and telling people with acne-prone skin to for-go moisturizer at night (even if it's only some nights) is such 90s acne care beliefs, I am shocked. The feeling of this treatment is a thick gel that dries down and feels tight immediately and the smell is very off-putting! It's somewhere between burnt toast and burnt sugar mixed with chemicals. I have normal skin that gets oilier in summer and this still felt horrible on my skin, I cannot imagine someone with dry skin trying to use it! (People with dry skin get acne too!) I'm just surprised to see this from Inkey as a Kbeauty brand when the Korean approach to acne is gentle and moisturizing. All skin types should be using moisturizer and I think you'd get far better results for acne using calming/soothing ingredients at night.

    Hello Allison,

    Thank you for taking the time to share your feedback, we truly appreciate your perspective on your experience with our C-50 Blemish Treatment.

    For optimal absorption, we typically recommend skipping moisturiser on the nights you use this treatment. However, if you prefer to include a moisturiser in your routine, that’s absolutely fine, we just suggest allowing around 10 minutes after applying the C-50 to let it fully absorb before layering.

    While we’re not a K-Beauty brand, we wholeheartedly agree with the philosophy that hydration plays a vital role in maintaining healthy, balanced skin.

    We're sorry to hear that this product wasn’t the right fit for you on this occasion. If there’s anything further we can do to support you, please don’t hesitate to reach out to our askINKEY Team, we’re always here to help 🖤
