How this list is built: products are grouped by what they are formulated around and who they suit, drawn from public information. Order is not a ranking of quality and nothing here is paid placement. Formulas change — read the current ingredient list before you buy.
1
For normal, oily or combination skin that already tolerates actives and wants the strongest well-documented form of vitamin C rather than a comfortable derivative. Good for the look of uneven tone, dullness and lingering post-blemish marks. Sensitive, rosacea-prone or barrier-compromised skin should not start here — the lower-strength version of the same serum exists for exactly that reason.
2
Dry and normal skin wanting dewiness, and combination skin that finds most brightening serums drying. Sensitive skin generally tolerates it, with the caveat that niacinamide makes some people flush. Anyone with a bee-product allergy should skip it entirely. Very oily skin often finds the propolis tack unpleasant, and there are lighter niacinamide serums for that.
3
Dry, normal and mature skin looking for hydration with a bit of bounce, and anyone drawn to the herbal end of Korean skincare. Combination skin can use it at night. Snail mucin is mollusc-derived, so vegans and anyone with a shellfish or mollusc sensitivity should avoid it. Oily skin prone to congestion sometimes finds the film heavy under sunscreen.
4
Normal, dry and combination skin working on the appearance of post-blemish marks and general unevenness, and a reasonable first step for anyone who found vitamin C too irritating. Oily skin will like the finish. It is not a fast fix for stubborn melasma, and anyone dealing with that should be talking to a clinician rather than shopping — topical brighteners alone rarely settle it.
5
Normal, combination and mildly dry skin that wants a comfortable everyday niacinamide rather than a clinical one. Good for the look of dullness and rough texture. People who flush from niacinamide will flush from this too. If you dislike scented skincare, the peach note is noticeable enough to be a dealbreaker, and fragrance-free niacinamide serums are easy to find.
6
Normal, combination and oily skin working on the appearance of post-blemish marks and diffuse unevenness. It suits people who found vitamin C too unstable or too irritating. Very sensitive skin should be careful — ten per cent niacinamide is enough to make some faces warm and pink. Anyone with diagnosed melasma should treat this as a supporting player and see a clinician about the rest.
7
Sensitive, combination and blemish-prone skin dealing with the look of persistent redness and lingering marks. It is a reasonable option for people who cannot tolerate acids or retinoids. Anyone with diagnosed rosacea should be having this conversation with a clinician, who can prescribe the higher strengths that the evidence actually rests on. Very dry skin may need extra moisturiser over the top.
8
Oily, combination and congested skin that wants a mild everyday exfoliating step rather than a weekly strong one. Reasonable for the look of rough texture and visible pores. Dry, sensitive or barrier-compromised skin should stay away, and so should anyone already using a nightly retinoid. If you have inflamed cystic breakouts, this is not the product and a clinician is the better call.
9
Dry, normal and combination skin recovering the look of comfort after a period of over-exfoliation, and sensitive skin that gets on with snail mucin. Good alongside, not instead of, sun protection when you are watching post-blemish marks fade. It is mollusc-derived, so not for vegans. Very oily skin often finds the film heavier than it wants in summer.
10
Every skin type, which is unusual and mostly a function of how little is in it. Particularly useful for dehydrated oily skin that wants water without oil, and for sensitive skin between stronger products. It is not a moisturiser and will disappoint anyone expecting one. If your skin is dry rather than dehydrated, you need the cream more than you need this.
11
Normal, combination, dry and mature skin curious about the ingredient and comfortable paying for the novelty. It is a decent light hydrating serum with a comfortable finish and no obvious irritants. It is salmon-derived, so not for vegans or anyone avoiding fish-derived ingredients. If your budget is finite, a retinoid and a sunscreen have far more evidence behind them for the look of ageing.
12
Normal, combination and mildly dry skin wanting an everyday hydrating step that vanishes under makeup, and oily skin that dislikes heavier serums. It suits people who want something pleasant rather than something active. It will not do much for pigmentation, texture or lines — this is a hydration and comfort product wearing an antioxidant story.
13
Sensitive and combination skin that flushes easily, and normal or dry skin that wants a calming layer without weight. It sits well in a routine that uses stronger actives on alternate nights. Anyone already using an inexpensive centella ampoule is unlikely to see a difference worth the price gap. Fragrance-avoidant skin should read the current pack carefully.
14
Dry, flaky and sensitive skin, and mature skin that has become less comfortable over time. Useful in winter and in air conditioning. Oily skin rarely needs it. If you are buying one product from this range, the cream is the more logical purchase — a ceramide serum without an occlusive over it is doing half a job, which the range's own structure quietly admits.
15
Sensitive, dry and normal skin looking for a soothing layer with slightly more substance than a watery centella ampoule. It suits people building a minimal routine after over-treating their skin. Combination skin can use it year-round. Anyone whose main complaint is congestion or texture will find it beside the point — nothing here exfoliates or resurfaces.
16
Normal, dry and combination skin starting with vitamin C, and reasonably sensitive skin that cannot take a high-strength serum. Good for the look of dullness and lingering post-blemish marks. Anyone already comfortable on a stronger ascorbic acid will find this underpowered. It is not the answer to deep pigmentation, and it is not a substitute for sunscreen in any routine.
17
Normal, combination, oily and dry skin looking for the look of a more even tone without the sting and instability of pure vitamin C. A sensible option for people who tried ascorbic acid and gave up. Anyone with established pigmentation who wants visible change will need more than this, plus rigorous sun protection, and probably a clinician's input if it is melasma.
18
Combination, oily and normal skin working on the look of post-blemish marks and general unevenness, and dry skin that finds most tone serums stripping. It is a reasonable everyday step rather than a corrective one. People who flush from niacinamide should be careful, and anyone with a bee-product allergy should check the current formula, as the brand has used honey-derived ingredients across its range.

🙋 People also ask
What is the difference between essence and serum?
In Korean skincare, essence is typically a thinner, hydration-focused layer that preps skin, while serum is more concentrated with targeted actives like vitamin C or niacinamide. Essence usually comes first; serum follows. The line between them blurs, and not every routine needs both.
Is Korean skincare worth it?
Korean skincare is often considered good value for its texture-focused, innovative formulations at accessible prices, with a gentle, barrier-first philosophy many find effective. Whether it's worth it depends on individual skin, consistency and choosing products for your needs rather than following every trend or step.
What is the difference between essence, serum and ampoule?
Essence is the lightest and most hydration-focused, serum is more concentrated and targeted, and ampoule is the most concentrated of the three. The boundaries are marketing convention, not regulated definitions.
