How it works
The texture is light and fast sinking, which is what a serum needs to be to go under a moisturiser without piling up. A few drops cover the whole face, and the finish it leaves is close to bare skin rather than glossy. A more even looking tone comes from weeks of consistency rather than from any single application, which is why this kind of step is judged by the month. An ampoule is the same idea at a higher strength and a shorter course, while a serum is the everyday version of it. The result you can judge yourself is whether your tone looks more even in the same light over several weeks.
Key benefits
- On this formula's own list, Ascorbic Acid shows up near the top. It is a vitamin C derivative included for its brightening, antioxidant role.
- This one's ingredient list carries Butylene Glycol near the top, a multifunctional glycol that carries moisture and helps preserve the formula.
- Allantoin sits in the back half on this product's own ingredient list, a soothing agent that supports comfort on sensitised skin.
Key actives
Ascorbic Acid
Ascorbic Acid is pure vitamin C, the form with the longest record for the look of uneven tone, and it is also the least stable, so a fresh bottle behaves better than an old one.
Glycerin
Glycerin holds water in the upper surface and is the reason a simple formula can still leave skin feeling supple an hour after it goes on.
Alpha-Bisabolol
Alpha-Bisabolol is the comfort ingredient from chamomile, added to strong vitamin C formulas because a high acid base needs something to soften how it feels.
Allantoin
Allantoin is one of the quiet ingredients on a list: no marketing story, a long record of being well tolerated, and a softening effect on rough feeling skin.
Betaine
Betaine is a plant derived humectant that holds water without any tackiness, which is what lets a watery formula feel light rather than sticky.
What is Vitamin C 23 Pure Vitamin C Boost Serum 15ml?
It is a targeted serum from Frankly, made for anyone bothered by uneven tone and by the look of the dark marks a breakout leaves behind. It goes on after your toner and before your moisturiser, so it reaches clean skin rather than sitting on a cream. The result you can judge yourself is whether your tone looks more even in the same light over several weeks.
Where does Vitamin C 23 Pure Vitamin C Boost Serum 15ml go in my routine?
It goes on after your toner and before your moisturiser, so it reaches clean skin rather than sitting on a cream. In practice: Press three or four drops over the face after your toner, then follow with your moisturiser once it has settled. Applying it out of that order is the usual reason a step seems to do nothing.
Is Vitamin C 23 Pure Vitamin C Boost Serum 15ml right for my skin type?
It is aimed at anyone bothered by uneven tone and by the look of the dark marks a breakout leaves behind. The skin types we would put first are normal skin, combination skin and dry skin. Tone work is slow work, so photograph the same area in the same light every fortnight rather than judging it in a different mirror each week.
Can I use it in the morning and at night?
Most people can, and the honest answer depends on what else is in the routine. Using it twice a day is fine when nothing else you apply is a strong treatment step. If your evenings already carry an acid or a retinoid, keep this to the mornings so you are not stacking working steps on tired skin.
Is this Vitamin C 23 Pure Vitamin C Boost Serum 15ml the authentic Korean-market formula?
Yes. We stock the Frankly Korean-market formula rather than a version reformulated for US shelves. The bottle you open is the 15ml one sold on Korean shelves, with Korean-primary packaging and an intact barcode you can check yourself.

How to use
- Use it after cleansing and toning, while the surface is still slightly damp.
- Press three or four drops over the face and neck rather than rubbing them in.
- Wait until it feels dry to the touch, then apply your moisturiser over the top.
- Do not apply it over a cream or an oil, since a light serum cannot get through a finished occlusive layer.
Worth knowing
- Patch test on a small area first, since tone focused steps are the ones most likely to sting on reactive skin.
- Give it several weeks of consistent use before you judge it, and change one thing at a time in your routine.
