Firming Décolleté Serum – DIY Recipe

The delicate skin of the décolleté is particularly prone to losing firmness and developing wrinkles.
If you want to effectively improve its tightness, elasticity, and smoothness, it’s worth choosing ingredients with lifting, moisturizing, and regenerating properties.

Below you’ll find a simple yet highly effective recipe for a décolleté serum that you can easily prepare at home using cosmetic raw materials available from densiLab.

Why does this serum work?

The formula is based on four powerful active ingredients and lightweight plant-derived squalane, which work together to deliver comprehensive benefits:
• Instant lifting and smoothing effect
• Skin filling and regeneration
• Deep hydration and improved elasticity
• Contour modeling and firming
• Lipid barrier protection
