Hale & Hush Rare C Serum

Hale & Hush Rare C Serum is a vitamin C serum built specifically for skin that has struggled with the irritation, oxidation, or instability that can come with traditional vitamin C formulations. The star active is 3-O-ethyl ascorbic acid, a stable, highly bioavailable ether derivative of vitamin C that delivers consistent results without the sensitivity concerns associated with L-ascorbic acid. This serum is fragrance-free.

Key Benefits

Visibly Minimizes Pores: 3-O-ethyl ascorbic acid has been shown in clinical studies to reduce the appearance of pore size by 20% within four weeks of consistent use.

Supports Collagen and Firmness: Vitamin C in the form of 3-O-ethyl ascorbic acid directly stimulates collagen production, helping skin feel firmer and reducing the appearance of fine lines and wrinkles over time.

Evens and Brightens Skin Tone: Vitamin C inhibits excess melanin production, gradually fading uneven tone and bringing a more consistent, healthy-looking complexion to the surface.

Deep Hydration with Barrier Support: Sodium hyaluronate draws moisture into the skin while beta-glucan helps soothe and reinforce the skin barrier, keeping skin comfortable and resilient with each use.

Calms and Protects with Botanicals: Mugwort extract and algae extract work together to deliver antioxidant protection and help neutralize environmental stressors that contribute to dullness and premature aging.

If your skin has reacted poorly to traditional vitamin C serums in the past, whether with stinging, redness, or breakouts, this serum was formulated with you in mind. The 3-O-ethyl ascorbic acid used here is significantly more stable and gentler than L-ascorbic acid, making it a strong option for sensitive, reactive, or redness-prone skin types.

This serum also suits anyone dealing with uneven skin tone, visible pores, early signs of aging, or skin that has lost firmness over time. It works well for all skin types, including acne-prone and post-procedure skin, and is formulated to be non-comedogenic.

If you want the brightening and collagen-supporting benefits of vitamin C without compromising your skin's comfort, Hale & Hush Rare C Serum belongs in your routine.

This serum can be used around the eye area in the evening, making it a smart addition on top of your eye cream for targeted brightening and firming where skin is thinnest and most delicate.

Prepare: Cleanse and tone skin thoroughly before applying.

Apply: Dispense a small amount and smooth onto the face, neck, and chest.

Frequency: Use in the morning and/or evening. Follow with your moisturizer or layer with other serums as desired. Always apply broad-spectrum SPF in the morning when using this serum.
