It's a bold cosmetic product, so it's difficult to combine with other cosmetics, but so far it looks good!
I'm in my 40s and have combination skin, and I regularly struggle with occasional red pimples along my face line and persistent blackheads on my nose. Since harsh products can actually irritate my skin, I was searching for a gentle acne treatment that caught my eye. AESTURA's Terakune 365 Serum caught my eye. Since a cream from the same series suited my skin, I was excited to try it, using it morning and night for about three weeks. First of all, the texture is quite light and smooth, blending in easily. Immediately after application, I felt a slight tightening sensation on my skin, giving me the impression that it might actually control sebum. However, this feeling was only temporary, and over time, my T-zone became oily as usual, and there was no noticeable change in my blackheads. Overall, my honest impression is that it's not bad, but it's not great either. It did feel like my skin was softer, and there was no irritation, so I guess it's okay in the sense that it gently tones the skin. However, it doesn't really seem to directly address acne, so those seeking immediate results and impact might be a little disappointed. The moisturizing effect is also modest, giving the impression of a formula focused on conditioning. While it may be suitable for those with oily skin or those with dry, inner-dry skin that tends to feel sticky, this alone isn't enough for dry, combination skin. It may dry out at night if you don't cover it properly with a moisturizing cream. It's scentless, and the bottle's simple, clean appearance is appealing. It could be useful as a "safe serum" for when your skin is unstable and irritated no matter what you use, but considering the price, you might be hesitant to repurchase. Overall, it seems like a good choice for those who prioritize gentleness and find minimal care that doesn't irritate the skin is enough, but it may be too mild for those looking for noticeable results on acne and pores.
I saw this in a pop-up store and tried it out before buying it. I get occasional pimples, so I use this on a spot basis. I like that it's a serum, so it spreads easily and isn't sticky. I haven't finished the whole bottle yet, so I've rated it as good. It has no smell and is easy to use.
I really like AESTURA's cream, so I've been using this serum for about three weeks. Immediately after use, I felt like it controlled my sebum, but the effect didn't last very long, and I didn't notice any effect on the blackheads and pores on my nose. It did soften my skin, but it was neither good nor bad, and at this price, I don't think I'll be repurchasing it.
It's neither good nor bad.
