KEY BENEFITS

Intelligent Hydration System

Tri-Luronic Complex combines three complementary forms of hyaluronic acid — each selected for its molecular weight and function — to deliver hydration at multiple levels of the skin, not just the surface.

Visibly Plumper, More Supple Skin

Improved Elasticity and Bounce

Clinically demonstrated to improve skin elasticity for skin that appears more resilient and bouncy.*

Healthy-Looking Glow

Rainbow algae and fermented sugars help smooth and revitalize skin for radiance that comes from healthy-looking skin—not surface shine.

Barrier Support

*Based on a 32-subject clinical study after 4 weeks, used twice daily.

FORMULATION APPROACH

AN INTELLIGENT APPROACH TO HYDRATION

Many brands treat hyaluronic acid as a single ingredient designed simply to add moisture to skin. Counter takes a more intelligent approach.

The Counterglow collection is built around an Intelligent Hydration System, a philosophy that recognizes that not all hyaluronic acid is created equal. Each Counterglow formula features a carefully selected form of hyaluronic acid chosen for its unique structure, function, and role within the product. Combined with skin-nourishing ingredients, Counterglow is designed to do more than hydrate—helping nourish, support, and preserve healthy-looking skin for a balanced, radiant glow.

For Tri-Luronic Hydrating Serum, we combined three complementary forms of hyaluronic acid—each selected for its unique molecular weight, function, and hydration benefit. Together, they help deliver immediate hydration, support moisture retention, and promote longer-lasting hydration at multiple levels of the skin.

This is hyaluronic acid designed to work with skin, not just sit on top.

Clinically tested. Rigorously screened for safety. Counterglow is formulated for skin that isn’t just hydrated—it’s so healthy, it glows.

FORMULATION FACT 01

Formulated without heavily ethoxylated ingredients such as Polysorbate 20 that carry particular risk for carcinogenic contaminants, ethylene oxide and 1,4-dioxane. We take ingredient purity seriously.

FORMULATION FACT 02

We never formulate with per- and polyfluoroalkyl substances (PFAS) - “forever chemicals” that can accumulate in our bodies and that have been linked to cancer, weakened immune systems, reproductive and developmental harm, and hormone disrupting effects.

FORMULATION FACT 03

We use Cystoseira tamariscifolia extract for its antioxidant, skin conditioning, and age-defensive benefits instead of Macrocystis pyrifera (Kelp) extract or Undaria pinnatifida extract, which can sometimes contain higher levels of iodine. Some algae, particularly brown seaweeds, naturally accumulate iodine from seawater as part of their growth process. While iodine is an essential trace element for healthy thyroid function, excessive exposure—especially in sensitive individuals—can disrupt thyroid hormone balance. Indeed, the Environmental Working Group (EWG) Verified program enforces strict limits on iodine levels in products containing brown algae. We carefully review and monitor the iodine content of all algae-derived extracts used in our formulations.

FORMULATION FACT 04

All seaweeds are algae, but not all algae are seaweeds. While seaweeds are valued in serums for their hydrating and antioxidant benefits, some species can pose risks due to the presence of hormone-like compounds, pro-oxidant activity, or heavy metal accumulation. We carefully review all seaweed ingredients for potential contaminants and look to avoid species with concerning evidence of endocrine activity and oxidative stress.

What makes Tri-Luronic Hydrating Serum different from other hyaluronic acid serums?

Many hyaluronic acid serums rely on a single form of hyaluronic acid to attract
moisture to the surface of skin. Counterglow Tri-Luronic Hydrating Serum combines three complementary forms of hyaluronic acid — each selected for its unique molecular weight and function — to deliver hydration and support moisture retention at multiple levels of the skin. This is part of Counter's Intelligent Hydration System, a formulation philosophy built on the principle that not all hyaluronic acid is created equal.

Why does this serum contain three forms of hyaluronic acid?

What is the Intelligent Hydration System?

The Intelligent Hydration System is Counter's formulation philosophy behind the
entire Counterglow collection. Rather than treating hyaluronic acid as a single commodity ingredient, Counter selects a specific form of hyaluronic acid for each product in the regimen — chosen for its unique molecular weight, structure, and role at that particular step. Counterglow Tri-Luronic Hydrating Serum is the fullest expression of that system, combining three forms of hyaluronic acid into a single formula.

Is Counterglow Tri-Luronic Serum good for dry or dehydrated skin?

Yes. Counterglow Tri-Luronic Hydrating Serum was designed for anyone whose skin
needs more than a temporary moisture boost. Powered by three forms of hyaluronic acid, it helps deliver hydration and support moisture retention at multiple levels of the skin — making it especially effective for skin that feels dry, tight, or lacking in bounce and suppleness. It layers seamlessly into any routine and works well paired with the Counterglow Adaptive Moisture Lotion or Counterglow Hyaluronic Cushion Cream for deeper hydration support.

How quickly will I see results?

Many people notice an immediate difference in how their skin feels — softer, more comfortable, and more hydrated — right after the first use. With continued use, Counterglow Tri-Luronic Hydrating Serum is clinically demonstrated to improve hydration, improve skin elasticity, and minimize the appearance of fine lines after four weeks.*

*Based on a 32-subject clinical study after 4 weeks, used twice daily

Does Counterglow Tri-Luronic Serum help with the appearance of fine lines?

Yes. In a clinical study, Tri-Luronic Hydrating Serum was shown to improve hydration,
improve skin elasticity, and minimize the appearance of fine lines.* For more targeted visible renewal and firming, Countertime Retinatural®+ Advanced Super Serum is specifically designed to address fine lines, firmness, and skin renewal.

*Based on 32-subject clinical study after 4 weeks, used twice daily

Should I apply Counterglow Tri-Luronic Serum before or after moisturizer?

Can I use Counterglow Tri-Luronic Hydrating Serum with vitamin C, retinol, other skin care products?

Does Counterglow Tri-Luronic Hydrating Serum contain retinol?

No. Counterglow Tri-Luronic Hydrating Serum is a dedicated hydration serum focused on delivering and supporting moisture retention through Tri-Luronic Complex and complementary skin-nourishing ingredients.

For visible renewal and retinol-like results, the Countertime Retinatural®+ Advanced Super Serum is powered by our Retinatural®+ Advanced Renewal Complex—a blend of clinically studied retinol alternatives designed to deliver visible renewal without the irritation and sensitivity commonly associated with traditional retinoids.

Retinoic acid and retinyl palmitate—derivatives of retinol (vitamin A)—are on The Never
List®. When applied to the skin in the presence of sunlight, these ingredients
may increase the risk of skin cancer and skin sensitization. Read more about these ingredients and The Never List® here.

What is Counter's approach to clean?

We define “clean beauty” as beauty products developed to meet a high standard for both
performance and safety.

Every Counter product is formulated with human health and safety in mind, according to publicly available criteria that guide how we evaluate ingredients, develop formulas, and make decisions about sourcing and packaging. Because transparency matters, we publicly share the standards behind our products. Read more at counter.com/thestandard
