NIACINAMIDE · N-ACETYL GLUCOSAMINE · HYALURONIC ACID · BETA-GLUCAN
HALO™ is a clinical-strength, multi-benefit treatment serum created for skin that needs more from a single step. Rather than layering one serum for hydration, another for brightening, another for barrier support and still another when skin feels stressed, HALO™ brings those priorities together in one intelligently edited formula. Each ingredient is chosen for a reason and used at an effective concentration to do meaningful work in the skin.
At the center of the formula is Niacinamide paired with N-Acetyl Glucosamine (NAG), a clinically studied combination that helps improve the appearance of discoloration and uneven tone while supporting healthy skin function. Hyaluronic Acid and Sodium PCA replenish and bind essential moisture, helping dehydrated skin appear smoother and plumper, while Beta-Glucan and Panthenol provide soothing hydration and support a strong, resilient skin barrier.
Together, they address many of the concerns I see repeatedly in the treatment room: dehydration, dullness, uneven tone, visible discoloration, rough texture, fine dehydration lines and a compromised barrier. With consistent use, skin feels deeply hydrated, smooth and comfortable, while the complexion appears clearer, more even, plumper and naturally luminous.
Why I Made It
After years of treating thousands of faces, I've become much less interested in how many products someone is using and much more interested in whether the products they're using are actually doing something meaningful for their skin. More isn't necessarily better, and five overlapping serums shouldn't be required to address several skin concerns.
I created HALO™ to be the workhorse serum I wanted my clients to have at home: sophisticated enough to address multiple skin priorities at once, yet gentle enough to become part of an everyday routine. If you want serious skincare but don't want a complicated routine or a shelf filled with overlapping serums, HALO™ was created to give you more from one beautifully considered formula.

Key Ingredients
Niacinamide
Vitamin B3
Niacinamide is one of the most extensively studied ingredients in modern skincare, with benefits that reach far beyond basic hydration. A form of vitamin B3, it is especially valued for brightening uneven skin tone, improving the appearance of dark spots, strengthening the skin barrier and smoothing visible texture.

N-Acetyl Glucosamine | NAG
N-Acetyl Glucosamine, often called NAG, is a naturally occurring amino sugar and one of the more fascinating ingredients for uneven skin tone, dark spots and dullness. It has been studied for its ability to help reduce the appearance of excess pigmentation while also supporting hydration and healthy skin renewal.
Read more →Hyaluronic Acid
Sodium Hyaluronate
Hyaluronic Acid is naturally present throughout the skin and has an extraordinary ability to bind and retain water. That makes it one of skincare’s most valuable ingredients for dehydration, tightness, fine dehydration lines and skin that has lost its fresh, plump appearance.
Read more →Beta-Glucan
B-Glucan
Beta-Glucan is a naturally occurring polysaccharide found in sources including oats, yeast, mushrooms and certain algae. Once known primarily for its immune-modulating properties, it has become an increasingly important skincare ingredient because it does something particularly valuable: it helps skin hydrate, calm, repair and become more resilient at the same time.
