Niacinamide 10% Facial Serum - Hydrating Anti-Aging Treatment

In this review of the Eight Saints Original Cin 10% niacinamide serum, the bottom line is practical: this is a straightforward, everyday serum for people who want visible improvements in skin texture and hydration without heavy fragrances or gimmicks. It pairs a clinically relevant 10% niacinamide concentration with hyaluronic acid to target enlarged pores, uneven tone and fine lines, and it absorbs quickly so it fits both morning and evening routines. The formula is natural-forward, cruelty free and made in Maine, making it a solid choice for those who prefer cleaner labels.

Key Features

• 10% Niacinamide: Helps reduce the appearance of fine lines and evens skin tone when used consistently.
• Hyaluronic Acid: Provides hydration and helps skin feel plumper, offsetting dryness that can make lines more noticeable.
• Aloe Vera: Calms redness and soothes sensitive areas while supporting overall skin comfort.
• Lightweight Texture: Absorbs quickly without leaving a greasy residue, making it easy to layer under moisturizers or sunscreen.
• Fragrance Free and Cruelty Free: Suitable for fragrance-sensitive users and those who prefer ethically produced skincare.
• Made in USA: Formulated and bottled in Maine with globally sourced ingredients for transparent manufacturing.

Who It's For

This serum is best for people with normal to dry or combination skin who want to reduce enlarged pores, even out complexion and add hydration without a heavy feel. Users who appreciate a simple ingredient list and no added fragrance will find it especially appealing.

It is also appropriate for newcomers to active skincare because the formula pairs niacinamide with hydrating hyaluronic acid rather than stronger acids or retinoids. Those looking for aggressive exfoliation or immediate dramatic resurfacing should look for products with stronger actives instead.

Pros & Cons

• Lightweight, fast-absorbing texture that layers well under moisturizers and makeup.
