Fortify peptide serum (30 ml)


prevent and reduce wrinkles and fine lines while protecting your skin's barrier

  • palmitoyl tripeptide-5 significantly boosts collagen production and inhibits its degradation.  It also visibly reduces the appearance of wrinkles, significantly reverses visible signs of photo-aging, and refines pore appearance.
  • acetyl hexapeptide-8 (argireline) works within the skin's surface layers to interrupt the appearance of expression lines.  It prevents dynamic wrinkles from forming by repeat facial movement, such as squinting. It also stimulates collagen production.
  • pentapeptide-18 reduces the depth of wrinkles caused by the contraction of muscles, especially in the forehead and around the eyes. It works synergistically with acetyl hexapaptide-8.
  • 3 ceramides strengthen the skin’s barrier, improving texture and elasticity.
  • olive squalane and hyaluronic acid hydrate and moisturize.
  • rosemary extract’s antimicrobial benefits help prevent future breakouts.

the perfect day or night preventative product for all skin types of all ages

recommended usage: one pump on clean skin every evening before bed.  Follow with Hydrate ceramide lotion.

    Texture, texture, texture!

    This serum has done wonders for the texture and overall appearance of my skin. I've dealt with skin dullness over the years, and haven't found a product that's really treated the root cause quite like this one! It's also non-greasy, and sinks into my skin effortlessly. Yay!

    Game. Changed.

    This product (mixed with Hydrate) has literally changed the texture of my skin. Pores? Smaller. Breakouts? No longer an issue…not even during my period. Fine lines? Gone. No joke this is my only skin care brand from now until forever.
    This is my first ever product review and I had to comment because if you can purchase one product from this site—make it this one!!!

    My favourite serum in the world. Literally.

    I love this serum. It makes my skin feel so hydrated and smooth. If there were more stars to give I would. Highly recommend this product.

    The best night serum + the smell is UNREAL

    Out of the 3 Relativskin products, this one is my fav. It's perfectly balanced to be a staple in your nighttime routine, and I absolutely LOVE the smell. It always makes me feel calm and happy right before bed. I use this just with the moisturizer and occasionally throw on an additional night oil, but it works really well on its own. I was always firmly under the impression that you weren't doing skincare right if you didn't have a 20 minute pre-bed routine involving layering 14 different products, but this little serum has really changed my mind :)

    I'm a Believer!

    Fortify has done just that!! From the moment it goes on you can feel it 'fortifying' your skin and making those lines and wrinkles disappear. Again, for someone who has sensitive skin, there have been no issues and my skin loves this product. I love how my skin looks using this product in tandem with the Moisturizer and the Nourish Serum. Can't recommend enough!!
