Product details

As the finishing touch for sensitive and reactive Skin Instants®, this lightweight, protective serum minimizes excess oil, boosting radiance and resilience. Its formula helps balance seborrheic tendencies and visibly calms stressed complexions without leaving behind residue or shine.


With a silky, second-skin texture, this serum reinforces the skin barrier, comforts fragile areas, and imparts a soft glow with a matte effect. Antioxidant-rich botanical extracts, silk proteins, and adaptogenic ingredients help defend against environmental stress while bringing out a healthier, more even-looking complexion. Skin feels smoother, firmer, and visibly refined.


SKIN SCIENCE

  • Seborrhea is a natural protective process, but when the skin’s balance is disrupted, it can trigger sensitivity and reactivity.
  • Sebaceous glands may become overactive or hypersensitive, leading to excess oil, redness, or irritation.
  • This formula includes soothing peptides, silk proteins, and adaptogens to help normalize oil flow and ease discomfort.
  • Regular use helps prevent skin “asphyxiation,” improves barrier resilience, and restores the skin’s natural luminosity.
how to use

Apply a few drops of the serum to the entire face, neck, and décolleté as the final step of your routine, morning and/or evening. Avoid contact with eyes. For external use only. Do not use on children under the age of 3. Avoid direct sun exposure after application.
