ROUND LAB prints the birch sap concentration on this pad, 10,000 ppm, which is one percent, and that small act of disclosure tells you two things at once: that the brand is willing to be precise about the ingredient it names its whole line after, and that the ingredient is a flourish. One percent of birch juice, eighth on the list, is a trace of amino acids and minerals riding on a formula whose real work is done by water, glycerin and four surfactants above it. That is fine. Cleansing pads live or die on their surfactant system and their after-feel, and this one is good on both, which is why the honest one percent matters less than the four ingredients the marketing never mentions.
Those four are sodium cocoyl alaninate, lauryl hydroxysultaine, disodium cocoamphodiacetate and sodium methyl cocoyl taurate, an amino-acid anionic, a sultaine, an amphoteric and a taurate, with sodium cocoyl isethionate and coco-glucoside further down and a little soap-bark saponin for natural-origin credit. It is a modern, low-irritation, low-foam system of the kind used in the gentlest face washes, and on a pad it does what it should: the embossed side lifts a day of sunscreen and light makeup in a few strokes with a faint foam, the soft side finishes, and the essence dries down within a minute to a face that is clean and slightly damp rather than squeaky. Glycerin at second, sodium hyaluronate and hyaluronic acid at tenth and eleventh and glyceryl glucoside just behind stay on the skin, since nothing is rinsed, and that leave-on humectancy is the entire difference between this and a foaming cleanser that sends its hydrators down the drain. Wormwood extract and ascorbic acid are the antioxidant garnish. The pads are large at eight centimetres and generously soaked, sixty to a jar with tweezers, and the few dozen reviews on the brand's site, plus a larger crowd at Amazon and YesStyle that cannot be counted from here, say the same things: one wipe does a bare-faced day, skin feels hydrated afterward, and the jar is enormous.
The limits are the format's. A wipe removes what it touches and leaves a film of what it dissolved, so on a sunscreen-only or tinted-moisturiser day it is a complete cleanse and on a full-makeup day it is the first step before an oil or balm and a rinse; waterproof mascara and long-wear foundation do not move, and the brand, to its credit, says as much by calling it step one on heavier days. Anyone who dislikes surfactant residue can follow with a splash of water and lose nothing. The other limit is the pair of essential oils at seventeenth and eighteenth, German chamomile and Scots pine, in a pad sold as unscented for sensitive skin and wiped across the eye area; the dose is low and most faces will never notice, but a leave-on wipe is a longer exposure than a rinse-off wash, and a chamomile-allergic or rosacea-prone face has better options. The brand uses the same two oils across its US range, and it is the one habit that undercuts an otherwise careful sensitive-skin formula.
The price is the other honest number. Twenty-four dollars for 60 pads is 40 cents a pad, so a nightly habit costs about $12 a month and a twice-daily one $24, against a bottle of comparable amino-acid cleanser at $15 that lasts three months. That is convenience pricing, and it is worth paying only if the pad replaces a step that would otherwise be skipped, which for the tired, the travelling and the bare-faced is a real category of person. The bulky jar is not for a bag; the format is for a bedside table. There is one more practical note worth making, because the two ROUND LAB birch pads share a jar design and a shelf: this is the cleansing pad, with surfactants, and the Birch Juice Moisturizing Pad beside it has none and is a toner step for after cleansing. Buyers mix them up often enough that the brand answers the question on its own site, and using the toner pad to remove sunscreen, or this one as a hydrating mask, gives each a reputation it does not deserve.
So: if you go bare-faced or sunscreen-only most days, want a one-step evening cleanse that leaves skin hydrated instead of tight, and like the ROUND LAB birch routine, this is one of the better cleansing pads made and the surfactant system is the reason. If you wear full makeup, it is your first step, not your only one; if your skin reacts to chamomile or you have rosacea, the essential oils are a reason to wipe with something else; and if the birch sap was the draw, it is one percent, and the brand told you so.
