Typically used at routine step 5.
The serum is where most of a routine's actual treatment happens. It carries the actives — niacinamide, hyaluronic acid, peptides, PDRN-labelled ingredients, vitamin C and so on — in a light base designed to spread thinly and absorb quickly. Because it is the step most likely to cause irritation, it is also the step to change least often. Layer thinnest to thickest, and give any new serum a fortnight before deciding whether it earns its place.
Editorial research reviewA lightweight humectant serum combining several forms of hyaluronic acid with panthenol, allantoin and barrier-supporting ingredients. It works best when sealed with moisturiser rather than used as the only hydration step.
Editorial research reviewBeauty of Joseon
A cushiony propolis and niacinamide serum that also contains betaine salicylate. It is a useful glow and oil-balance option for tolerant combination or oily skin, but it is not a substitute for acne treatment.
Editorial research reviewA lightweight salmon-derived PDRN capsule serum with several forms of hyaluronic acid, niacinamide, collagen and glutathione. It is primarily a hydrating and glow-focused serum, not a proven substitute for prescription treatment or procedures.
Editorial research reviewA moisturising salmon-derived PDRN serum with niacinamide, peptides and collagen-related ingredients. Its main immediate role is hydration and glow; the evidence for topical PDRN remains formulation-specific and less established than sunscreen or retinoids.
