The Renewal Serum

◆ The serum

Brighter, smoother, more even in 14 days.

5% niacinamide (vitamin B3) and 2% hyaluronic acid in a featherweight water-based serum. No fragrance, no alcohol, no filler — just the actives, at the concentrations proven in 4 published clinical trials.

The formula targets 6 signs of skin aging simultaneously: uneven tone, post-acne marks, fine lines, enlarged pores, dehydration, and barrier damage. 94% of trial participants saw brighter, more even skin in 14 days. 87% saw fewer visible pores in 8 weeks.

Use AM and PM after cleansing, before moisturizing. Layer under SPF in the morning, under your night cream at night. Pairs beautifully with our Vitamin C 15% in the AM and Retinol 0.5% in the PM.

◆ What's inside

8 ingredients. That's it.

5% Niacinamide. The most studied skincare active of the decade. Brightens, evens tone, strengthens barrier, minimizes pores.

2% Hyaluronic acid (3 molecular weights). Hydrates at 3 depths of the skin — surface, mid-dermis, and deep. Plumps fine lines from within.

1% Panthenol (pro-vitamin B5). Soothes, calms, and supports barrier repair. Especially good for sensitive or reactive skin.

0.5% Allantoin. A skin-soother that's been used for centuries. Reduces redness and irritation.

No. Fragrance. Alcohol denat. Parabens. Phthalates. Sulfates. Silicones. Dyes. Essential oils. Nuts. Gluten. Soy. 100% transparent.

Six weeks in, my skin has never looked better.

I've been through 4 different brightening serums in the last 2 years. None of them did what The Renewal Serum did in 6 weeks. The texture is smoother, the tone is even, and the post-acne marks from last summer are 80% faded. I'm on bottle 3. Won't switch.

My dermatologist recommended it.

My dermatologist recommended this for post-acne marks. After 8 weeks, the difference is visible to my eye and on the Visia scan she does in-office. The texture is featherweight — no pilling, no residue, plays well with my sunscreen and makeup. Holy grail status.

Finally a niacinamide serum that doesn't pill.

I've tried 5 different niacinamide serums. They all pilled under sunscreen or foundation. This one doesn't. Layering is finally easy. The formula is featherweight and absorbs in under a minute. I use it AM + PM, no issues. And the price is unbeatable for the concentration.
