Texture & Feel
Retinol B3 Serum
This serum has a lightweight, non-greasy, and fluid texture that glides effortlessly on the skin. It absorbs quickly and leaves a smooth, hydrated finish without stickiness. The formula has a mild fragrance, but it’s not overpowering. A small amount goes a long way.
Redermic R Retinol Cream
This cream features a silky, velvety texture that feels moisturizing without being heavy. It spreads evenly and leaves the skin feeling soft and luminous. Users report that it’s ideal for application on targeted areas like the forehead, crow’s feet, and upper lip.
How to Use
Redermic R Retinol Cream
- When to use: Ideally at night
- How to apply: After cleansing, apply to your face and neck. Use alone or underneath a moisturizer.
- Tip: Avoid the eye area and always apply broad-spectrum SPF in the morning, as retinol can increase sun sensitivity.
This cream is particularly effective for treating deep wrinkles, sun-damaged skin, and uneven skin tone—while being safe for sensitive skin types.
Retinol B3 Serum
- When to use: Evening
- How to apply: After cleansing, apply 3–4 drops to the face and neck. Gently massage into the skin using your fingertips. Can be used alone or layered under a moisturizer.
- Beginner tip: If you’re new to retinol, start by using it 2–3 times per week, then gradually increase frequency as your skin builds tolerance.
This serum is ideal for those looking for a gentler introduction to retinol, thanks to its inclusion of niacinamide for soothing and hydration.
Price Comparison
| Product | Size | Approx. Price |
| Retinol B3 Serum | 30 ml | $44.99 |
| Redermic R Retinol Cream | 30 ml | $54.99 |
The Redermic R Retinol Cream is slightly more expensive, which reflects its more concentrated retinol content and inclusion of Lipo-Hydroxy Acid for extra exfoliation. The Retinol B3 Serum remains a more budget-friendly option, especially for beginners or those with sensitive skin.
