Lovi Assistant explains

  • This serum offers excellent plumping and firming benefits for your combination skin, as bio-mimicking peptides like sh-oligopeptide-2 and sh-oligopeptide-1 work to enhance skin elasticity and reduce the appearance of fine lines.
  • Zinc PCA and peptides like Sh-Polypeptide-1 further support your skin barrier function and help regulate sebum production, addressing your oily shine concerns.
  • The formula is safe for your skin, containing soothing ingredients like Glycerin and Panthenol with no harsh or prohibited substances.

How to apply

  • Use your serum as part of your PM routine. Start using it 3 times a week and move to daily use if your skin likes it.
  • Apply the serum after cleansing and toner, and right before your moisturizer.
  • Gently press 2-3 drops of the serum into your skin and wait a minute ⏳for it to soak in.
  • Apply the serum on clean and dry skin since your skin is not sensitive.
  • Always do a patch test before using the serum for the first time, and avoid the eye area .

People Say

★4.5Overall rating based on 300+ reviews

Users with mature, dry, or dull skin frequently praise this serum for its ability to visibly smooth fine lines and improve skin elasticity, often describing a "tightening" effect. While many appreciate its lightweight, hydrating texture and lack of irritation, a significant number of reviewers feel the high price tag is not justified by the results, and recent feedback suggests the product may be difficult to find or discontinued.
