Most peptide serums include one or two peptides as supporting ingredients. Le Mieux RX Complex Serum contains five distinct peptides, each targeting a different aspect of visible aging, from smoothing expression lines to supporting collagen pathways. On top of that, the formula layers in ten forms of hyaluronic acid, brightening actives like magnesium ascorbyl phosphate and tranexamic acid, and a multi-source antioxidant blend, making it a more complete treatment than a single-focus peptide serum.

The formula contains ten distinct hyaluronic acid derivatives, including sodium hyaluronate, hyaluronic acid, hydrolyzed hyaluronic acid, sodium acetylated hyaluronate, sodium hyaluronate crosspolymer, zinc hydrolyzed hyaluronate, hydroxypropyltrimonium hyaluronate, sodium hyaluronate dimethylsilanol, C12-13 alkyl glyceryl hydrolyzed hyaluronate, and ascorbyl propyl hyaluronate. These vary in molecular size and function, allowing moisture to be delivered and retained at multiple depths in the skin.

Le Mieux RX Complex Serum uses magnesium ascorbyl phosphate, a water-soluble, stable vitamin C derivative that does not oxidize the way L-ascorbic acid does. It is considered gentler on the skin while still effectively working to brighten tone and reduce the appearance of discoloration. This makes it a practical choice for skin that finds high-concentration L-ascorbic acid formulas too irritating.

Le Mieux RX Complex Serum is formulated with dry and dehydrated skin types in mind, but the formula does not contain heavy occlusives that would feel problematic on oily skin. That said, it is not specifically optimized for excess oil or breakout-prone skin. If you are unsure whether it is the right fit for your skin type, a free skincare consultation with one of our estheticians can help you decide.

This serum is not recommended for sensitive skin types. The concentration of active ingredients, including multiple peptides, niacinamide, tranexamic acid, and magnesium ascorbyl phosphate, may be too stimulating for reactive or easily irritated skin. If your skin leans sensitive, reach out for a free skincare consultation so our estheticians can suggest a better starting point.

Yes. Le Mieux RX Complex Serum pairs well with the Le Mieux EGF-DNA Serum. You can apply EGF-DNA Serum first and follow with RX Complex, or mix a small amount of both in your palm before applying. This approach layers growth-factor support with the peptide and brightening actives in RX Complex without adding extra steps to your routine.

The formula includes several antioxidant sources: superoxide dismutase, an enzyme that neutralizes free radicals directly in the skin; tocotrienols, a potent form of vitamin E; tocopherol, the classical vitamin E form; and galactomyces ferment filtrate, a yeast-derived ingredient known for its brightening and skin-conditioning properties. Together, these help defend the skin against oxidative damage that contributes to visible aging.
