How to use

Apply a small amount of serum to clean skin morning and evening. Gently massage until absorbed. Then follow with your usual skincare routine if desired. There is no limit amount and can be used as often as desired.

For an enhanced experience, we recommend using a facial roll-on applicator to gently distribute the product across the skin. This helps minimize direct hand contact, promotes even application, and supports absorption through a gentle massaging action.

    Gentle results without the retinol irritation

    I’ve tried several retinol products over the years, but my sensitive skin never seemed to tolerate them. I would get redness, tightness, and occasional peeling. With Sereline, I noticed hydration from the first day and my skin gradually became smoother and more plump without any irritation. It feels like I’m getting the benefits of an anti-aging routine without putting my skin through a recovery period.

    My under-eye area looks brighter than it has in years

    One of the first things I noticed with Sereline was how much healthier my under-eye area looked. After about two weeks, the dark shadows that constantly made me look tired appeared much lighter. Friends started asking if I had changed my makeup routine, but it was simply that my skin looked brighter, smoother, and more hydrated.

    More please!

    Retinol and other anti ageeing products made my skin feel stressed but also addicted to their products. As soon as I stopped the products, my skin will get so much worse than before starting them, like sagging and with more wrinkles and all of that just within a couple of months using them. I was stuck in a circle until I discovered Sereline. Sereline makes my skin feel healthy and strong. My skin looks smoother, softer, and more radiant while staying comfortable all day. I can also forget to apply it for a few days and it's like the serum is still working!? Absolutely no side effect like other creams. After a few days, my skin gradually comes back to how it used to be with no worse effect keeping the skin addicted to it! I can see and feel the difference. I will never switch back!

     Finally seeing a difference under my eyes

    I’ve tried countless eye creams over the years without much success. As Sereline advertised being useful around the eyes area, I decided to give it a go for my face AND around my eyes instead of buying multiple products. While I wasn’t expecting miracles, Sereline genuinely surprised me. The skin under my eyes feels plumper and more hydrated, and the appearance of my dark circles has noticeably softened. I look more rested, even on busy days.

    A smarter alternative for my skin

    Retinol always felt like a trade-off for me: better skin texture but also dryness and sensitivity. Sereline has been completely different. My skin feels comfortable, hydrated, and healthy every day. After a few weeks, my fine lines appeared softer and my complexion looked more radiant. I love that I don’t have to choose between results and comfort anymore.

    Less makeup needed= Less money spent

    I used to rely on concealer every day. Since using Sereline, my under-eye area looks naturally brighter and healthier, even without makeup

    Thank you!

    As someone with sensitive skin, Sereline gave me the confidence to follow an anti-aging routine again without the peeling, burning, or recovery time I experienced with retinol.

    Perfect for NZ weather!

    Living in New Zealand means my skin is constantly dealing with changing weather, strong winds, and dry indoor heating during winter. Since using Sereline, my skin feels far more hydrated and comfortable throughout the day. Instead of feeling tight and dry by the afternoon, my skin stays soft, plump, and balanced. It’s become an essential part of my daily routine.

    Finally something I can use every day

    I stopped using retinol during pregnancy and struggled to find an alternative that actually made a difference. Sereline exceeded my expectations. My skin feels firmer, softer, and more hydrated than it did with many of the retinol products I used before. The best part is that it feels incredibly gentle, even around my sensitive areas.
