DEBAIY Vitamin C Facial Serum with Niacinamide — 120ml Brightening Hydrating Daily Serum

DEBAIY Vitamin C Facial Serum is a multi-effect daily serum that combines a stable vitamin C derivative, niacinamide, ceramide T5 and hyaluronic acid to brighten, hydrate and help support a resilient skin barrier.

This lightweight 120 ml serum blends 2% 3-O-ethyl ascorbic acid (a stable form of vitamin C) with 3% niacinamide, 1% sodium hyaluronate and 1% ceramide T5 to target uneven tone, dryness and visible signs of early aging while remaining suitable for both morning and evening routines. Formulated for regular use, the concentrate absorbs quickly and layers well under moisturizers and sunscreens.

How will this serum affect dull or uneven skin tone?

The stable vitamin C derivative and niacinamide work together to reduce the appearance of dullness and create a more even-looking complexion. Regular application can help skin appear brighter and more balanced without heavy moisturizers.

• 2% 3-O-ethyl ascorbic acid supports a brighter surface tone
• 3% niacinamide helps minimize the look of dark spots and blotchiness
• Lightweight texture avoids cakey layering under makeup

Can this serum improve hydration and skin barrier function?

The formula includes sodium hyaluronate for moisture retention plus ceramide T5 to support the skin’s barrier lipids. Together they help the skin feel more supple and reduce dryness-related tightness.

• 1% sodium hyaluronate draws and holds moisture at the skin surface
• 1% ceramide T5 helps reinforce natural barrier structure
• Hydrating base suits daily AM and PM use under creams

How should I incorporate DEBAIY Vitamin C Serum into my routine?

Use a few drops on clean, dry skin after cleansing and before heavier treatments. In the morning follow with broad-spectrum sunscreen; at night layer a moisturizer on top. If you’re new to active ingredients, introduce it every other day and build up to daily use.

• Apply 2–4 drops to face and neck on cleansed skin
• AM: follow with sunscreen for UV protection
• PM: pair with your usual moisturizer or night treatment

Is this serum suitable for sensitive or combination skin?

The concentration of actives is moderate and the formula is non-greasy, making it adaptable for many skin types. Those with sensitive or reactive skin should patch test and introduce gradually to monitor tolerance, especially if using other actives.

• Moderate active levels: 2% vitamin C derivative, 3% niacinamide
• Non-oily texture layers well with other products
• Patch testing recommended for sensitive skin types

Who is this for: This serum is designed for anyone wanting a combined brightening and hydrating treatment—suitable for people with normal, combination, dehydrated or early-signs-of-aging skin who want a daily, easy-to-layer formula. It’s also a practical choice for those looking to consolidate routine steps by using one product that addresses tone, moisture and barrier support. Avoid if you have known allergies to any listed ingredients; consult a professional if you’re treating severe skin conditions.
