“I have the world’s most sensitive skin, and dermazen products in general have seriously been the best for me.”
— Daniel B
How It Works
-
1Protect and brighten
Sodium ascorbyl phosphate (SAP) protects against UV and oxidative stress, boosts collagen production, and brightens skin tone — without the irritation of ascorbic acid. -
2Rejuvenate with astaxanthin
Hawaiian super-nutrient astaxanthin improves skin elasticity, protects against UV damage, improves moisture content, and helps prevent and reverse wrinkles. -
3Hydrate deeply
Perfectly-sized hyaluronic acid (50-200k Daltons) penetrates deeply to hydrate and soothe — not too big, not too small.

Hydrating Vitamin C Serum
Purified water, sodium ascorbyl phosphate (vitamin C), niacinamide (vitamin B3), astaxanthin, squalane oil, glycerin, hyaluronic acid, 200x concentrated aloe vera, benzyl alcohol, xanthan gum, guar gum, sorbitol

Customer Testimonials
Trusted By Experts
“I have been recommending the Calming Seborrheic Serum to people struggling with seborrheic dermatitis and psoriasis and they have seen significant improvement in their skin.”
- Dr. Maria Bonilla
Why
Dermazen?
We started Dermazen because we lived the struggle personally: flakes, redness, embarrassment, and products that helped for a week…then stopped working.
So we went deep into the research and took a different approach: formulas that outsmart the yeast, simple routines anyone can follow, and holistic ingredients to calm our skin (without feeding future flare-ups).
