Not impressed. Felt a bit sticky on my skin and didn’t notice any difference after weeks. I’ve used cheaper brands that gave me better results.

This serum absorbs fast and doesn’t feel heavy. My face is so much softer after a week. The pump makes it easy to get just the right amount without wasting any product. I like how smooth my skin looks now; it’s really noticeable in sunlight.

This serum feels nice and moisturizing right after applying. My skin has a good glow now. Shipping was quick too, so that’s always great.
Beckett – Boston, USA –
This serum has a nice texture and feels light on my skin. I noticed improved hydration, especially during winter. It absorbs quickly and left no residue. The packaging is sleek too, making it easy to store. I’m happy with how my complexion looks now.
Nolan – Seattle, USA –
I noticed my face feels smoother and looks brighter after using this serum. It absorbs fast, so I can apply makeup soon. Shipping took a while though, over a week to arrive. I’d buy it again for sure.

Desde que comencé a usar el Serum Reparador Micro-Activo de Sum37, he notado una mejora notable en la luminosidad y suavidad de mi piel. La textura es fresca, casi como si estuvieras aplicando agua pura sobre tu rostro; se absorbe rápidamente sin dejar sensación pegajosa. Me encanta cómo mis mejillas adquieren un brillo natural tras cada aplicación, incluso esos días grises cuando necesito un impulso extra. Siento también que protege bien contra factores externos agresivos que suelen irritar mi cutis sensible.

Czerwień mych policzków w końcu odpowiada naturalnemu blaskowi. Mikroskórze obiecywane przez Sum37 to prawda! Po dniu spędzonym na jaskrawej varsavian akcji czuję, jak powracam do siebie dzięki temu serum!
Anneliese Weigand from München, Deutschland –
Ich hatte kürzlich die Möglichkeit, das Sum37 Micro-Active Repair Serum zu testen und ich bin überwältigt von dessen Wirkung! Nach nur einer Woche Anwendung fühlte sich mein Teint frisch an; es scheint fast so, als ob dieses Serum eine natürliche Lumineszenz freisetzt. Während andere Seren mir oft nach ein paar Stunden Schichtgefühl oder Hautreizungen gebracht haben, war dies nicht der Fall. Besonders spannend finde ich die Verwendung fermentierter Inhaltsstoffe – meine sensible Gesichtshaut reagierte unglaublich positiv auf diesen Ansatz. Wenn man Vergleichsprodukte im Bereich Anti-Aging sieht wie Biotherm’s Aquasource Hydration Spektral kommt kaum eins heran hinsichtlich Langzeiteffekten auf meinem Roséhautton.

このサム37のマイクロアクティブリペアセラムを使って以来、私の肌がどれほど活気づいたか信じられません。特に日本の冬は乾燥しやすいですが、このセラムはまるで冷たい泉から湧き出た水のような潤いを与えてくれるんです。トゥルーアクティブ™とバイオペプチド190™が組み合わさった成分が魅力的で、肌荒れにも悩んでいた私でも少しずつ改善されています。他の商品も試しましたけど、本品は明らかな違いがあります。その効果に感動しているので、友人にも勧めてます!
Clara Delaney from Floyd County, Virginia, USA –
In a little town nestled between the Blue Ridge Mountains, I stumbled upon Sum37’s Micro-Active Repair Serum. The subtleties of life in these hills can wear on one’s complexion. Ever since integrating this serum into my morning ritual, its delicate blend of Tru-Active™ and Biopeptide190™ brings an unexpected vitality to my skin that rivals the bright Appalachian sunrise. Each drop embraces my face without heaviness—more like a gentle summer breeze after a sultry day than any commercial product I’ve encountered. It’s become not merely part of a skincare routine but an infusion of renewal amid mountain air—a precious ally against the hardships brought by fluctuating temperatures here.
Mitsuhiro Tanaka from Osaka, Japan –
Transformed my winter-worn face! So hydrating, I hardly recognize myself. This is the warmth from Japan bottled for your skin!
Emily from San Francisco, USA –
This serum transformed my skin! Deep hydration and a visible glow. Worth every penny.
