Lovi Assistant explains

  • Excellent for normal skin, this formula leverages Hydroxyresveratrol and Tetrapeptide-30 to effectively target wrinkles and fine lines by promoting collagen synthesis and skin elasticity. Gluconolactone further aids in refining skin texture with its mild keratolytic action.
  • Glycerin and Sodium Hyaluronate provide excellent hydration, ensuring comfort and supporting the skin's barrier function without irritation.
  • The safety profile is excellent, with no risks of irritation due to the absence of harsh ingredients and the inclusion of soothing components.

How to apply

  • Use this serum in your PM routine. Start by applying it 3 times a week, and work up to daily use if your skin likes it.
  • Apply this serum after your toner and before your moisturizer.
  • Gently press 2-3 drops of the serum into your skin and let it absorb for a minute.
  • You can apply the serum on dry skin for the best results against fine lines.
  • Always do a patch test before your first use and avoid the sensitive eye area.

People Say

★4.4Overall rating based on 1.1k+ reviews

Based on a very large amount of data, users with hyperpigmentation, melasma, and post-inflammatory erythema (PIE) frequently report visible skin brightening and the fading of dark spots, often noting a smoother texture and "glass-like" glow within weeks. While many experience rapid results, a minority of users report no visible changes or mild breakouts, and the short shelf life of the activated formula is a noted consideration.
