TOUN28 Serums
TOUN28's serum lineup is built around named actives rather than a generic "brightening" or "anti-aging" label: propolis, the Haenam 404 peptide complex, and an AHA BHA PHA acid blend each get their own bottle. Sizes run 30ml to 60ml, with a couple of cream-plus-serum bundles for anyone who wants the matching moisturizer in one order. Everything listed here is currently in stock at skinsli.
Buying guide
How to pick a TOUN28 serum
TOUN28 splits its serums by active ingredient instead of a single flagship formula, so the right pick depends on what your skin needs rather than which bottle is trending. This guide breaks down the propolis line, the Haenam 404 peptide complex, the acid exfoliant, and the cream-plus-serum bundles so you can match a serum to a routine gap instead of guessing off the label.
The propolis serums
The plain Propolis Serum (30ml) is a calming, barrier-support formula, while the Propolis Vitamin C B3 B5 B6 Serum (30ml) adds brightening actives on top of the same propolis base. If your skin is reactive or easily irritated, start with the plain version; if you want propolis plus a brightening boost, go straight for the vitamin blend.
Haenam 404 Peptasica: what it's for
The Haenam 404 Peptasica Serum is a peptide-focused formula aimed at firmness and resilience, sold in both 30ml and 60ml. (You may see it spelled "Peptacica" on one listing - same product line, listing variance.) The 60ml bottle is the better buy if you already use it daily and don't want to reorder every few weeks.
AHA BHA PHA Serum: who it's for
The AHA BHA PHA Serum (also listed as "Ton 28 AHA BHA PHA Serum", 30ml) combines three acid types for exfoliation in one step. This is the one to reach for if your routine needs texture or dullness addressed, but it's not meant to be layered with other strong actives on the same night - give skin a buffer if you're also using a retinoid or another exfoliating step.
The cream + serum bundles
Haenam 404 Glow Cream and Serum (50ml) and Haenam 404 Peptasica Dawn Cream + Serum bundle the moisturizer with its matching serum in one order. These are worth it if you're building the routine from scratch and want the cream and serum formulated to work together, rather than buying and testing them separately.
Tone 28 Solution Serum Essence
The Tone 28 Solution Serum Essence sits between a toner and a serum in texture - lighter than the propolis or peptide serums, meant as an earlier layer in the routine rather than a finishing step. Apply it right after cleansing and before your heavier serums.
How to layer TOUN28 serums
A simple order that avoids conflicts: Tone 28 essence first, then the AHA BHA PHA acid serum on nights you're exfoliating, then propolis or Haenam 404 peptide serum on the nights you're not. Don't stack the acid serum with propolis Vitamin C the same night - alternate them instead to avoid irritation.
FAQ
Frequently asked questions
FAQ
Frequently asked questions
What's the difference between TOUN28 Propolis Serum and the Propolis Vitamin C B3 B5 B6 Serum?
Both share a propolis base. The plain Propolis Serum is calming and barrier-focused; the Vitamin C B3 B5 B6 version adds brightening actives on top of it. Pick the plain one if your skin is reactive, the vitamin blend if you want brightening too.
Should I get the 30ml or 60ml Haenam 404 Peptasica Serum?
The 60ml bottle is the better value if you already use the serum daily and don't want to reorder often. The 30ml is a lower-commitment size for trying the peptide formula first.
Can I use the AHA BHA PHA Serum with other TOUN28 serums?
Yes, but not on the same night as the propolis Vitamin C serum or another strong active - alternate them to avoid irritation. Use the Tone 28 essence first, then the acid serum on exfoliation nights.
Is the Haenam 404 cream and serum bundle worth it over buying separately?
The bundles pair a cream with its matching serum, formulated to work together, which is convenient if you're starting the routine from scratch. If you already have a moisturizer you like, the standalone serum works fine on its own.
Are "Peptasica" and "Peptacica" the same TOUN28 serum?
Yes - both spellings refer to the same Haenam 404 peptide serum line; the difference is a listing variance, not a different formula.
