Skin Renew Serum
I recently started using this serum. So far, it is as effective as other serums I've used to tighten the appearance of fine lines. It does not leave my skin feeling soft and hydrated, but then it doesn't claim to. So that's not a criticism, just an observation. Because I have complete confidence in Briotech products, I will continue to use this and measure the long term effects. I trust they will be as positive as their other trusted products.

Frequently Asked
Questions

Find answers to your most pressing questions about our innovative solutions and technology.

What is Hypochlorous Acid (HOCl)?

HOCl is a naturally occurring molecule of Hydrogen, Oxygen, and Chlorine. Produced by white blood cells in all mammals, it plays a key role in immune defense by neutralizing harmful elements and supporting recovery.

How do I use the Renew line in my skincare routine?

Apply Renew Toner to clean skin. Shake lightly and mist onto the face, morning and night. Follow with 1–2 drops of Renew Serum on clean, dry skin. Gently massage the serum into the skin, allow full absorption before applying moisturizer.

How does HOCl fight blemishes and reduce redness?

HOCl helps soothe irritation and balance the skin’s natural response, reducing the appearance of redness. Its gentle, anti-inflammatory properties also target impurities contributing to breakouts, supporting the skin’s natural healing process.

When should I use the serum vs. spray?

The spray is ideal for broad, general cleansing, while the gel offers a more concentrated treatment. The serum stays in place, dries faster, and delivers HOCl directly to the targeted area for focused relief and hydration.
