Description

Two Molecular Weights, One Deeply Hydrated Complexion

Tree To Tub's Double Action Hyaluronic Acid Serum for Face combines two forms of hyaluronic acid to hydrate skin's surface in two different ways that a single-weight serum can't match. Formulated with just four ingredients and no added fragrance, it's built for dry, dehydrated, or easily irritated skin that doesn't want extra noise in its routine.

Here's what makes it work:

  • Hydrates on Two Levels: High Molecular Weight Hyaluronic Acid helps draw moisture to the skin's surface for an immediate feel of hydration, while Low Molecular Weight Hyaluronic Acid helps keep the surface hydrated for longer, so skin doesn't feel under-quenched as the day goes on.
  • Softer, Smoother-Looking Skin: Consistent hydration helps skin appear more supple and comfortable, softening the visible look of fine lines and dryness over time.
  • Gentle Enough for Daily Use: With only four ingredients and nothing added for fragrance, this serum is formulated to feel comfortable on sensitive or reactive-prone skin, so hydration never comes with a trade-off.

Lightweight and fast-absorbing, it has a smooth, non-greasy finish that layers easily under moisturizer without pilling.

Every Tree To Tub formula is vegan, cruelty-free, and built around skin comfort first, not as an afterthought.

Whether your skin is chronically dry or just needs a hydration reset, Double Action Hyaluronic Acid Serum for Face delivers moisture at more than one level, without overcomplicating your routine.
