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
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.
2
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.
3
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.
4
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.
5
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.
6
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.
7
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.
8
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.

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.

What is 속건조 (inner dryness)?
속건조 describes skin that looks and feels oily on the surface while being tight and dehydrated underneath. It is why oily skin still needs hydration, and why stripping it makes things worse.
