Good Molecules Hyaluronic Acid Serum Duo — 2 x 75 ml Lightweight 1% HA, Dual-Molecular Hydration

Good Molecules Hyaluronic Acid Serum Pack delivers lightweight, multi-layer hydration with two hyaluronic acid molecules in two 75 ml bottles.

This duo combines a 1% hyaluronic-acid formula in easy-absorbing, water-light serums designed to replenish moisture, reduce the look of dehydration lines, and boost skin suppleness without heaviness or fragrance. Formulated with two molecular weights of HA to target different skin layers, the pack is presented in generous 75 ml (2.5 fl oz) bottles—ideal for at-home routines and travel. The formulation is vegan, gluten-free, cruelty-free, and has a pH around 5.8, making it gentle for daily use.

How does this serum hydrate different layers of skin?

The serum uses two forms of hyaluronic acid with distinct molecular sizes so water-binding happens at multiple depths. The lower-molecular-weight HA penetrates closer to the surface for immediate smoothing, while the higher-molecular-weight HA sits nearer the epidermis to lock in moisture longer.

• Contains dual-molecular hyaluronic acid for layered hydration
• 1% total HA concentration for effective moisture retention
• Lightweight, water-like texture absorbs quickly without residue
• Helps visibly plump fine lines caused by dehydration

When and how should I use these 75 ml bottles in my routine?

Apply a few drops morning and night after cleansing and while skin is slightly damp to maximize absorption. Gently pat the serum into skin, wait about 30 seconds, then layer with oils, creams, or SPF as needed. The larger bottle size makes it convenient for consistent daily use.

• Apply on damp skin to improve penetration
• Use before thicker creams or facial oils
• Suitable under makeup because it dries lightweight
• Two bottles provide value and continuity for longer-term hydration

Is this formula suitable for sensitive or acne-prone skin?

The serum is fragrance-free and formulated with a mild pH, which reduces potential irritation. Hyaluronic acid is non-comedogenic and designed to hydrate without adding oil, making it compatible with sensitive, dry, combination, and oily skin types. Always patch test if you have highly reactive skin.

• Fragrance-free and gentle pH (~5.8) to minimize irritation
• Non-comedogenic hydration that won’t clog pores
• Vegan and cruelty-free formulation
• Because it’s lightweight, it layers well with acne treatments

What practical benefits will I notice with regular use?

With consistent morning and night application, skin often appears smoother, more supple, and less prone to visible dehydration lines. The dual HA system helps sustain moisture throughout the day, supporting the appearance of firmness and bounce without heavy residue.

• Improved skin plumpness and reduced look of dehydration lines
• Longer-lasting moisture thanks to multiple HA weights
• Light, fast-absorbing feel suitable under makeup
• Two 75 ml bottles offer extended use or one for travel and one for home
