The Vitamin C13 Serum

product review positives
🌟𝐖𝐎𝐑𝐓𝐇𝐘 𝐈𝐍𝐂𝐈- •Ascorbic Acid (Vitamin C) [23%] •Squalane •Panthenol •Glutathione •Niacinamide •Tocopherol (Vitamin E) •Licorice Root Extract 💊𝙍𝙚𝙫𝙞𝙚𝙬💊 :: This lightweight oil-like serum comes in a 20ML opaque bottle. Initially, it had a slight tint of yellow & the classic raw hotdog water scent.🌭💦 :: Now, when it comes to vitamin C, I’m usually diligent & consistently track the PAO (period after opening).This vitamin C has the PAO of 2 months. :: The effectiveness of your vitamin C serum is completely depleted once it undergoes the oxidation process.So, I made sure to close the cap tightly & store in fridge right after opening. :: I really get bad anxiety when I can’t fully use up products or atleast more than half of it [if it’s hitting the PAO or expiry date] Don’t y’all worry, I used it till • almost 2 months period • :: Later, saved tiny bit so I can in fact observe how rancid and rust tone shade it’ll turn out to be.🤓🧡 TBH the difference you notice here is bcos of my current/existing routine & not alone this vitamin C. HOWEVER, I’m not gonna discredit the fact that it did in fact speed up the process for getting rid of PIH / PIE. :: Efficacy ~ 4.5 ⭐️ out of 5
product review negatives
:: User-experience ~ 2 ⭐️ out of 5 [ I prefer using products without the hassle of possible irritation or shelf stable for 6 months (ATLEAST!!) ]
