The application
Apply to clean skin in the morning and evening after cleansing. If you use a toner or mist, apply that before the serum.
Smooth a small amount over areas of uneven tone or across the face, then press lightly until absorbed. Avoid rubbing too hard so the layer stays even.
Once absorbed, seal in the treatment step with moisturiser. In the morning, always finish with broad-spectrum SPF.
What to expect
The serum should feel comfortable and lightweight as soon as it is applied. Skin may feel more hydrated and less tight, with no heavy residue.
Tone may begin to look a little more even where dryness was making marks appear more obvious. The skin should feel consistently cushioned under your next layers.
With regular use, the look of post-blemish marks and uneven surface tone may appear softer and less contrasted. Results depend on consistent application and daily SPF use.
The deeper detail
The formula's base is built around Glycerin, organically sourced, and Caprylic/Capric Triglyceride for a clean, lightweight emulsion that spreads easily and absorbs without residue. Sunflower Seed Oil, organic, provides the linoleic-dominant lipid foundation. Alpha-Arbutin, derived from bearberry, works by inhibiting tyrosinase activity at the melanocyte, reducing the rate of melanin production at hyperpigmented sites without the irritation associated with more aggressive brightening actives.
Bidens Pilosa Extract provides complementary action on surface tone. Astrocaryum Murumuru Seed Butter and Gossypium Herbaceum Seed Oil contribute emollient depth. Flaxseed Oil brings a high alpha-linolenic acid content for barrier-repair lipid support. Ascophyllum Nodosum Extract, a brown algae, provides marine polysaccharide hydration alongside its antioxidant mineral content. Hydrolyzed Hyaluronic Acid and Sodium Hyaluronate address hydration at the surface and deeper epidermal layers simultaneously.
The fragrance architecture is provided by Citrus Lemon Peel Oil, Pogostemon Cablin Oil, Juniperus Virginiana Oil, and Cedrus Atlantica Oil : a woody, grounding blend with citrus brightness, all declared in full in the INCI. For best results and to prevent any reactivation of pigmentation, follow with a broad-spectrum SPF every morning.

From our community
Hydration from the hyaluronic content feels decent on my sensitive skin, though pigment changes are still minimal, tbh.
Mentioned by sister, fine texture under makeup, lighter gels and serums.
Twice daily, the cadence feels really steady, with less midday shine, better hydration and a more even nose area.
gentle under cream, no sting, looks clearer
Few drops morning and night. Not depleted by evening. Couple of stubborn patches on my cheeks look softer.
light in summer, still helps cheeks look more even
Sat under moisturiser oddly. Scent not my thing.
Twice daily, this serum feels super smooth and keeps my color looking less reactive.
I was worried the oils would be too much but it's actually really lightweight. Goes on clean, doesn't clog my skin at all. Uneven tone has improved a bit, nothing dramatic but it's working. Sits well under my moisturiser and doesn't feel heavy through the day. Happy with it so far.
Honestly one pump does my whole face. The dispenser is good because you don't waste product. Texture is light, presses in without sliding everywhere. My old blemish marks are looking less obvious, which is what I bought it for. I use it before SPF and it layers perfectly, no pilling or anything.
I used this after a long flight and noticed my skin looked more even by morning, which I liked. My nose was still a touch dry, so I’d pair it with a richer cream, but overall it does what I wanted.
My skin reacts to everything but this felt fine. Comfortable from day one. Surface tone on my cheeks looks a bit clearer after a few weeks. Sensible rather than flashy.
Cold weather leaves my skin a bit blotchy, but this serum evens things out well and gives a fairly healthy glow.
I had dark spots from old breakouts and this has helped. Not sticky, spreads evenly before cream. After a couple of weeks the marks looked less obvious which is all I wanted really.
Works. Tone looks more even. Prefer less scent.
Light, easy, skin doesn't feel dry by lunch.
Honestly, got it as a gift for partner, the box looked neat and understated, then it stayed on the bathroom shelf after evening use.
Woody smell lingers. Performance is good though.
Skin feels more comfortable through the day and the tone looks a bit less patchy in natural light. Dropper gives just enough without waste which I appreciate.
Absorbs quickly, layers fine, but results slower than I hoped. Scent is stronger than I'd choose for daily.
Absorbs fast on my normal skin. Old marks have faded a bit. Layers cleanly under cream, no grease.
Got this as a present, she loved it. Looked premium without being too much.
Used it for weeks. Dispenser was handy and texture is nice but my dark spots didn't really shift. Absorbs well but I needed more obvious results for the price.
Love this, it gave my skin a more even look and made makeup go on smoother. The finish feels super even and my color looks nicer overall. Totally happy with how it works.
Scent caught me first. Vetiver and cedar, bit of citrus. Presses in cleanly, skin feels cushioned not tight.
Absorbs fast under my moisturiser and has helped fade a few dark spots on my cheeks after a few weeks. Scent is fine, though the bottle feels a little small.
Formula makes sense. Absorbs quickly, sits comfortably under my moisturiser. Does what it should.
Been using this on post-blemish marks along my jaw. Two drops from the dispenser is enough for my whole face. Lightweight, disappears fast so my moisturiser doesn't drag over it. After a few weeks the blotchy tone looked less obvious, especially in daylight. Kept with it and it's been worth it.
The mix feels considered rather than gimmicky. Hydration is noticeable. Change in dark spots has been slow but the serum is comfortable and sits well under my night cream.
Doesn't fight with my moisturiser. Spreads easy, absorbs quick.
Im fair and marks hang around on me. This took a few weeks but the uneven tone became less obvious. Lightweight texture makes it easy to use daily.
Decent serum, fair improvement overall. It calmed blotchiness between cleanse and moisturiser, though I still wanted cream when it was colder.
Change has been gradual but real. Layers under SPF fine.
Tolerance was there, because it is a retinol alternative and redness looks less visible while skin tone seems more even.
Tone support is decent. The woody citrus fragrance is stronger than I expected for a treatment step. Still works well under moisturiser so im continuing.
After a month old blemish marks looked less obvious. Clean finish, earthy scent, doesn't mess with my cream.
Skin looks less patchy. Disappears quickly. Keeps everything feeling balanced. Like it before daytime moisturiser.
tried this after my old one ran out and I use it right after my morning shower. Smells fresh for a while, which I like, though the cap is a little annoying.
I have combination skin and usually lose interest after a week but this kept me going because the surface tone looked more even without any fuss. Earthy woody scent is unusual for a serum but it suits the light texture. Use it at night and wake up with skin that feels supported, not tight or rough.
Tiny amount on freshly washed skin, then moisturiser over the top, then my base went on with less fuss. Tone looks more even overall, though the effect is still fairly subtle. It feels careful and tidy, really if you want something that works quietly.
After first day back at the office, it helps fade dark spots and keeps skin feeling totally free of grease.
It smooths the look of texture and my forehead looks better, though I wish for a bit more glow.
Absorbs fast. No residue. Sits under foundation perfectly.
It did help the uneven tone around a post-blemish patch on my cheek. Don't love the vetiver and cedar fragrance though, which stops me buying again. Texture itself is lightweight.
The texture seemed a bit plain at a glance, but after a few uses my skin looked less patchy and more gentle overall. It feels decent for reactive skin, honestly.
Lightweight. Redness eased by bedtime.
