Description
Hyaluronic acid serum with niacinamide for deep hydration
A dehydrated skin is different from a dry skin — a confusion that leads to wrong product choices in many routines. Dry skin lacks oil and lipids; dehydrated skin lacks water. The result is skin that still looks dull, tight, and with fine lines despite a rich cream, because the underlying moisture need has not been addressed. Hyaluronic acid is the most targeted ingredient in these cases, provided it is in the right formulation.
Cosmedix Surge is a lightweight booster serum with 1.5% hyaluronic acid in three different molecular weights. The large molecules form a hydrating film on the skin surface, while the smaller molecules penetrate deeper for long-lasting hydration from within. Niacinamide strengthens the skin barrier and kiwi water provides a natural dose of vitamin C for an extra radiant effect. The self-dosing cap makes every application hygienic and economical.

Active ingredients
1.5% hyaluronic acid in three molecular weights: Hyaluronic acid is a natural component of the skin that can bind up to 1000 times its own weight in water. Surge combines sodium hyaluronate (a high-molecular form that works on the surface), hydrolyzed hyaluronic acid (a lower molecular weight that penetrates deeper), and a third fraction that serves the zone in between. This multi-level approach provides both immediate and long-lasting hydration.
Niacinamide (vitamin B3): Strengthens the skin barrier and helps retain moisture in the skin — a crucial complement to hyaluronic acid, as hyaluronic acid without a healthy barrier evaporates faster. Niacinamide also improves skin texture, reduces the visibility of pigmentation spots, and soothes redness.
Kiwi fruit water (Actinidia Chinensis): A natural source of vitamin C that nourishes the skin and brightens. Gives Surge a slight radiant effect on the complexion and contributes to a healthy-looking glow without the irritation of pure ascorbic acid.
Carrageenan extract (Chondrus Crispus): A red algae extract with film-forming properties that create a 'second skin' on the surface. Reduces trans-epidermal water loss (TEWL) and helps the hydrating effect of the other ingredients last longer.
Glycerin: A classic humectant that draws water from the environment and deeper skin layers to the skin surface. Works synergistically with hyaluronic acid for an immediate hydrating effect that is noticeable upon application.
Fruit extracts of apple, grape, kiwi, lemon, and lime: A natural cocktail of vitamins, antioxidants, and skin-friendly fruit acids that refresh the complexion and protect the skin from oxidative damage.
Lavender and geranium extract: Botanical extracts that give the ritual a pleasant, fresh scent and do not burden sensitive skin.

Frequently asked questions
What is the difference between dehydrated and dry skin?
A dry skin is a skin type: there is a structural lack of sebum and lipids. A dehydrated skin is a condition that any skin type can experience, including oily skin: there is a lack of water. Surge targets the second group. Those with both dry and dehydrated skin should combine Surge with a nourishing cream or oil as a final step.
Can I use Surge after a professional treatment or peel?
Cosmedix does not specifically recommend Surge in the first days after a professional treatment, as the skin then needs a different type of support. The products in the Post Treatment Starter Kit (Benefit Clean, Cell ID, C.P.R., Hydrate+ SPF) are better suited for that. Surge can be added once the skin is fully healed, usually after three to four weeks.
When in my routine should I apply Surge?
Surge is applied after cleansing and optionally toning, before a day or night cream. When using an active serum (such as Define, Simply Brilliant, or Affirm), apply that serum first, let it dry for a few seconds, then apply Surge. Hyaluronic acid works better on slightly damp skin.
Can I use Surge during pregnancy or breastfeeding?
Yes. Surge contains no retinoids, salicylic acid, or other ingredients that are discouraged during pregnancy or breastfeeding. The formula is suitable for those seeking hydration during these periods without worry.
How does the self-dosing cap work?
The cap is designed to deliver a precise, hygienic dose with each use without a pipette or pump that contacts the outside world. Twist the cap once to loosen, gently press the top down, and the correct amount is automatically dispensed. This prevents contamination and keeps the serum fresh until the last drop.
