The Rhonda Allison Antiox Defend Tonic is a daily antioxidant toning solution that works on two fronts: clearing the skin of buildup and debris while defending it against the environmental stressors that accelerate aging and trigger breakouts. It carries a light, botanical scent from geranium and grapefruit peel oils that makes the application feel intentional rather than clinical.

Key Benefits

Neutralizes free radical damage Superoxide dismutase and glutathione (L) work together as a two-enzyme antioxidant system to intercept oxidative stress before it can break down collagen or trigger inflammation.

Brightens and smooths skin texture Mandelic acid (L), an alpha hydroxy acid derived from bitter almonds, gently loosens dead cell buildup so skin looks clearer and feels more even without the irritation of stronger AHAs.

Firms the appearance of pores Witch hazel water and mandelic acid work together to tighten and visibly minimize enlarged pores with consistent daily use.

Reduces follicular breakouts Mandelic acid's antibacterial properties help keep pores clear and reduce the frequency of breakouts tied to congestion and follicular buildup.

Supports collagen synthesis Ascorbic acid (L) and mandelic acid both contribute to new collagen formation, helping skin maintain firmness and resilience over time.

If your skin is regularly exposed to urban pollution, cigarette smoke, or other environmental aggressors, this tonic gives your skin a daily layer of antioxidant defense that your cleanser alone cannot provide. It is especially well-suited for oily, acne-prone, or combination skin types dealing with clogged pores, uneven texture, or recurring breakouts.

This tonic also works well for those who want the exfoliating benefit of an AHA without the sensitivity that comes with glycolic acid. Mandelic acid has a larger molecular size, meaning it absorbs more slowly and is less likely to cause redness or irritation, making it a smart choice for skin that has not tolerated stronger acids in the past.

Anyone who shaves regularly and experiences post-shave bumps or irritation will find this tonic particularly useful as a calming, clarifying step that helps prevent ingrown hairs and follicular inflammation.

If you shave regularly, apply the Antiox Defend Tonic immediately after shaving as a post-shave toning step. The mandelic acid and witch hazel combination helps calm irritation, reduce redness, and prevent the follicular breakouts and ingrown hairs that often follow shaving.
