Hydrinity
The serum our providers reach for most, deep, multi-level hydration with peptide support for firmer, more radiant-looking skin.
Targets
Hydrinity's signature serum, RENEWING HA goes beyond surface moisture. A supercharged, dual-weight hyaluronic acid pairs with a six-peptide complex to deeply hydrate while supporting a firmer, more radiant, more youthful-looking complexion. Lightweight and fast-absorbing, it's the serum our providers reach for most as the foundation of a healthy-aging routine.
Skin showing early-to-moderate signs of aging, fine lines, loss of firmness, or dullness, and anyone wanting a hydrating daily treatment serum.
Why we carry it, from our providers
Of all the hydrating serums we've tried, Renewing HA is the one our providers keep coming back to. It does what a good daily serum should. It layers beautifully, absorbs fast, and leaves skin genuinely hydrated rather than dewy for an hour, which is why it anchors most of the healthy-aging routines we build.

The brand behind the product
Hydrinity is a professional skincare line built around what it calls Accelerated Skin Science: advanced hyaluronic acid and antioxidant formulations developed for use alongside clinical care.
The line is built on a simple premise: hydration is foundational to healthy skin, and how hyaluronic acid is delivered, not just whether it's present, determines how well the skin is actually supported.
Hydrinity formulates around its proprietary HydroLink Delivery System, pairing multiple molecular weights of hyaluronic acid with antioxidants and peptides so hydration and actives are carried into the skin rather than sitting on the surface. Formulas lean clean and fragrance-conscious, with an emphasis on tolerability for sensitive and post-procedure skin.
A newer name among professional skincare houses, Hydrinity grew out of a focused study of hyaluronic acid and has built a following among aesthetic providers for its hydration-first, antioxidant-rich formulations.
Where many hyaluronic acid serums rely on a single molecular weight, Hydrinity's signature is a multi-weight, delivery-focused approach, and a consistent thread of antioxidant support, including glutathione, running across the range.
The proprietary HydroLink Delivery System and Hydrinity's supercharged, multi-molecular-weight hyaluronic acid complexes are what the brand is best known for.
Renewing HA is built on Hydrinity's HydroLink Delivery System, which carries multiple molecular weights of hyaluronic acid, along with antioxidants and a six-peptide complex, into the skin rather than leaving them on the surface. The dual-weight hyaluronic acid hydrates at more than one depth, while the peptides support the look of firmness and renewal.
Apply 2 pumps to clean face and neck, morning and evening, before moisturizer.
It uses a dual-weight, supercharged HA plus a six-peptide complex, so it supports firmness and radiance alongside hydration, not just a surface moisture boost.
Skin often feels more hydrated right away; visible improvements in tone and texture build with consistent daily use over several weeks.
A simple, provider-designed daily rhythm: hydrate and protect in the morning, renew at night.
