G.M. Collin Antioxidant 20 Serum – Medical Line High-Potency Antioxidant Treatment (30 ml)

G.M. Collin Antioxidant 20 Serum is a professional-tier 20% antioxidant complex from the G.M. Collin Medical Line — formulated to neutralize the free radicals, UV stress, and environmental pollutants that drive premature aging, dullness, and uneven skin tone. The lightweight serum absorbs cleanly and layers under SPF for maximum daily protection.

Who It Is For: Anyone with visible signs of environmental damage — sun spots, dullness, fine lines, loss of radiance, uneven tone. Particularly valuable for city dwellers, frequent travelers, and clients investing in in-clinic anti-aging treatments who want to extend results.

Key Benefits: The 20% antioxidant complex provides clinical-grade free radical defense, helping prevent and visibly improve the appearance of oxidative damage. Brightens overall complexion, fades surface pigmentation over time, supports collagen integrity by protecting the dermal matrix, and primes the skin to perform better with every other active you layer on top.

How It Fits Your Routine: Apply 4–6 drops every morning after cleansing, before moisturizer and SPF. For best long-term anti-aging results, pair with A.G.E. Skin Defense Cream and a 0.5% or 1% Retinol Complex Night Cream at night.

Step 1: Cleanse and pat skin dry.

Step 2: Dispense 4–6 drops onto clean fingertips.

Step 3: Press evenly over the face, neck, and decolletage. Avoid the eye area.

Step 4: Allow 60 seconds to fully absorb.

Step 5: Follow with moisturizer and SPF 30+ daily — antioxidants are most effective in combination with sun protection. Use every morning.

Will it irritate my skin?
The Medical Line formula is engineered for daily tolerability. Most clients tolerate it well, but introduce gradually if you have sensitive skin — every 2nd day for the first week, then daily.

Can I use it with Vitamin C from another brand?
This IS your Vitamin C product. Doubling up on antioxidants doesn't add benefit and may add irritation. Use this and skip other antioxidant serums.

Morning or night?
Morning. Antioxidants work synergistically with SPF to defend against daily UV and environmental damage.

Can I use it with retinol?
Yes — antioxidants in the morning, retinol at night. Don't layer them in the same routine.

Is it pregnancy-safe?
Yes — no restricted actives. Safe for pregnancy and nursing.

How long until I see results?
Brightness within 2–3 weeks. Tone evening at 6–12 weeks. Prevention benefits compound over years.

**Antioxidant 20 Serum** is the morning serum we wish every client used. At Le Petit Spa Charlotte, we see the impact of cumulative environmental damage every single day — sun spots, dullness, fine lines, that "tired" look that no amount of cleanser can fix. The cause is free radical damage from UV, pollution, blue light, and oxidative stress. A **20% antioxidant complex** at clinical concentration is the most cost-effective defense we can prescribe. This Medical Line formula delivers that punch in a lightweight serum that layers cleanly under SPF. Pair it with daily SPF and you've built the foundation that makes every other anti-aging investment (retinol, peels, microcurrent, injectables) work harder and last longer. It's a workhorse — quietly preventing damage every single day so you don't have to chase it later.
