DERMA FACTORY Niacinamide 20% Face Serum — Rose Water & Glycerin, Lightweight Oil-Control for Oily/Combination Skin, 1.01 fl oz

DERMA FACTORY Niacinamide 20% Serum is a lightweight facial serum combining a high dose of niacinamide with rose water and glycerin to help oily and combination skin feel balanced and hydrated without greasy residue.

This serum targets the needs of oily and combination complexions by pairing a concentrated 20% niacinamide active with soothing Rosa damascena flower water and humectant glycerin. Designed in a clear, watery texture, it layers well after toner and before moisturizer for both morning and evening routines. The formulation aims to deliver oil-control comfort and lightweight hydration that won’t weigh skin down.

How does this serum control oil while still hydrating?

The 20% niacinamide works alongside glycerin and a high proportion of rose water to manage shine and support skin barrier moisture. Rather than adding heavy oils, it uses humectants to draw and retain water, giving a balanced finish.

• 20% niacinamide concentration for targeted oil-regulating support
• 64.5% Rosa damascena flower water for a fresh, non-greasy hydration base
• 8% glycerin to attract and lock in moisture without heaviness
• Watery, fast-absorbing texture that layers easily under creams

Is this serum suitable for sensitive or reactive skin?

The formula is lightweight and free from heavy emollients, but a high 20% niacinamide concentration can be potent for sensitive users. Patch testing and gradual introduction are recommended to assess tolerance.

• Start with a small amount or alternate days for initial use
• Apply after toner to minimize direct contact with active-rich cleansers
• If irritation occurs, reduce frequency or dilute with moisturizer
• Consult a dermatologist for guidance if you have highly reactive skin

How do I incorporate this into my daily skincare routine?

Use the serum after cleansing and toning, then follow with a moisturizer and SPF in the morning. Because of its thin, non-sticky feel, it layers well under most creams and sunscreens.

• Cleanse, tone, then dispense a few drops of serum onto fingertips
• Press gently over face and neck until absorbed
• Follow with moisturizer; apply SPF in daytime routines
• For sensitive skin, start with every other night and build up

What results can I expect and how long until I notice them?

Visible changes depend on individual skin and consistency of use. Many users notice reduced surface shine and a smoother feel within a few weeks, while longer-term improvements in skin texture may take consistent application over 6–12 weeks.

• Immediate: lightweight hydration and matte-finish feel
• Weeks: reduced excess oil and improved skin texture
• Ongoing: more balanced skin appearance with regular use
• Monitor tolerance and adjust frequency as needed

Who is this for: This serum is aimed at people with oily or combination skin who want targeted oil-control without heavy creams. It suits users who prefer a Korean-style, watery serum formulation and are comfortable introducing a concentrated active into their routine. If you have very dry or highly reactive skin, consider starting slowly or choosing a lower-strength niacinamide product.
