On the fence...
Will be updating review after I have used it for more than a week.
But so far here are the pros and cons:
Pros:
Smells good
Seems like a little goes a long way
Easy to apply
Cons:
Not sure if this is because I didn't use Sulfate free shampoo, but felt like with one wash I didn't get all the product out of my hair, so when It dried, it still looked greasy/oily
Will be washing my hair again with sulfate free shampoo, then will do another application in another day or so.
it says to use 2-3 times a week, so I'll use it 3 times a week for 2 weeks and then come back and update my review. But so far, it seams like a good product and for the money, it's a fair value.

good product
Effectiveness:
This serum focuses on brightening, uneven tone, and early signs of aging using two stabilized forms of vitamin C plus supportive antioxidants. With consistent use, it can help improve overall radiance and reduce the look of dark spots gradually rather than delivering fast, dramatic fading.
Texture & Application:
Lightweight, silky, and smooth. It spreads easily and absorbs quickly without feeling greasy or heavy. The airless pump helps keep the formula stable and prevents oxidation, which is important for vitamin C products.
Key Ingredients Performance:
Vitamin C (two stabilized forms) supports brightness and antioxidant protection
Kojic acid ester helps even skin tone over time
Oryzanol (rice bran antioxidant) helps enhance brightening effects and supports skin defense
Overall, it’s a gentler vitamin C approach compared to high-strength L-ascorbic acid serums, making it more suitable for sensitive or beginner users.
Skin Feel / Finish:
Leaves a soft, natural finish with no sticky residue. It layers well under moisturizer and sunscreen and doesn’t pill when used correctly. Suitable for daily AM or PM use.
Durability of Results:
Improvements are gradual—typically noticeable after several weeks of consistent use. Best results come with daily sunscreen use since vitamin C works synergistically with UV protection.
Value:
Very strong value for a budget-friendly serum. It delivers multiple brightening ingredients at a low price point, making it accessible for everyday skincare routines.
Overall:
A gentle, affordable vitamin C serum that prioritizes steady brightening, antioxidant support, and skin tone improvement over high-intensity results. Best for beginners, sensitive skin, or anyone wanting a simple daily glow-boosting step.

Amazing Vitamin C at an Affordable Price!
This Vitamin C serum from Good Molecules is honestly one of the best I’ve tried! The texture feels so smooth and lightweight on the skin, it absorbs quickly and leaves my face feeling hydrated without being sticky. It’s super effective for fading acne scars and dark spots, and I always notice extra brightness and glow the next morning after using it.
What makes it even better is how affordable it is compared to other Vitamin C serums—such great quality for the price! Plus, the bottle lasts a long time since just two pumps are enough for the entire face. Gentle scent, hydrating, effective, and budget-friendly… I couldn’t recommend it more
