Le Mieux Hyaluronic Serum

Most hyaluronic acid serums rely on one or two molecular weights, which means hydration is delivered to only one or two layers of the skin. Le Mieux Hyaluronic Serum uses 10 distinct forms of hyaluronic acid, each with a different molecular weight and delivery mechanism, so moisture reaches the surface, the mid-layers, and deeper down simultaneously. The addition of polyglutamic acid further reinforces this by holding onto moisture and preventing it from evaporating.

The formula includes hyaluronic acid, zinc hydrolyzed hyaluronate, sodium hyaluronate, hydroxypropyltrimonium hyaluronate, sodium hyaluronate dimethylsilanol, sodium hyaluronate crosspolymer, C12-13 alkyl glyceryl hydrolyzed hyaluronate, hydrolyzed hyaluronic acid, sodium acetylated hyaluronate, and ascorbyl propyl hyaluronate. Each one has a distinct molecular size or modification that affects how deeply it penetrates and how it interacts with the skin.

Yes. The formula is lightweight, non-comedogenic, and free of fragrance, which makes it appropriate for acne-prone and breakout-prone skin. Dehydrated skin is a common trigger for excess oil production, and keeping the skin properly hydrated with a serum like this one can help stabilize that cycle. It is also an excellent companion serum for anyone using active acne treatments that tend to dry out or sensitize the skin.

Polyglutamic acid is a naturally derived peptide known for its exceptional ability to bind and retain moisture, with research suggesting it holds up to four times more water than hyaluronic acid. In this formula it acts as a second-layer humectant, helping to lock in the hydration delivered by the 10 hyaluronic acid forms and prevent moisture from leaving the skin throughout the day.

It is an ideal pairing with both. Retinoids and exfoliating acids accelerate cell turnover but can compromise the skin barrier in the process, leading to tightness, flaking, or sensitivity. Applying Le Mieux Hyaluronic Serum consistently helps counteract that by maintaining hydration levels and supporting barrier recovery. Apply the serum before your moisturizer, and if layering with an active, apply the active first and follow with the serum to calm and hydrate.

Le Mieux Hyaluronic Serum has a pH range of 5.7 to 6.7, which aligns with the skin's natural acid mantle. This means the formula is compatible with the skin's own environment and will not disrupt barrier function or cause irritation when used alongside other products in a routine.

Because the formula is a lightweight gel with a smooth, non-greasy finish, it creates a hydrated, even base that foundation adheres to well. You can apply it directly to the skin before makeup, or mix one to two drops into your foundation to add moisture and improve the way the base blends and sits on the skin. It does not pill under makeup and will not break down your base throughout the day.
