Your genie in a beautiful glass bottle. Ask it for a denser and more elastic skin, for a brighter complexion and tighter pores and for an instant hydrating effect.

Minimalistic placenta-based formula fortified with Vitamin C, peptide and arginine contains the bare minimum of inactive ingredients and NO parabens, alcohol, or synthetic fragrance. Very light. Fast absorption.

Use it as a SOS-care for a stressed and tired skin or as a regular care to get a denser, more elastic and translucent skin. Use if for the area around the eyes to get a lifting and brightening effects.


Laennec Diaserum has a perfect combination of ingredients to care for aging and problematic skin. Give it a try if you already have first signs of aging and still suffer from break outs now and then.

Why we like it:

Improves the overall quality of the skin:

  • Fights dullness and hyper-pigmentation: increases cell turnover and regulates production of keratin
  • Makes skin firmer and more elastic: facilitates production of elastin and collagen
  • Provides deep hydration: replenishes amino acids and sugars in the skin, the elements that attract water 

How to use:

Use it after cleansing and a lotion. Take 1-2 pumps and apply it with upward massage movements all over the face including the area around the eyes. Always cover your serum with a cream. It will work deeper and longer.

A lot of Japanese customers noted that paired with the cream from the same line the serum gives quicker results.

Active ingredients:

  • Placental extract: multi-functional ingredient with anti-aging, anti-pigmentation, and anti-inflammatory and hydrating effects
  • Arginine: boosts collagen production
  • Hexapeptide-8: Botox-like effect
  • Alpha-arbutin: suppresses melanin production
  • Sasa Kurilensis water (bamboo water): hydration
  • Raffinose: a trisaccharide composed (galactose, glucose, and fructose) found among others in beans and broccoli. Supports skin barrier function and maintains its hydration.
  • Oat kernel extract: moisturizing and anti-inflammatory effects
  • Tremella fungi polysaccharide: hydration
