Adding Ceramide & Niacinamide to Finished Lotion for Post-Acne Skin

Adding active ingredients to an existing finished lotion is generally not recommended. Finished lotions are formulated for stability, and adding other ingredients can potentially destabilize the formula, affect its texture, or reduce the effectiveness of both the added ingredients and the original lotion. It's also difficult to precisely control the concentration of added ingredients in a finished lotion.

However, the ingredients you are interested in, Ceramide Complex and Vitamin B3 (Niacinamide), are excellent and very beneficial for your skin condition after acne treatment, which often involves a weakened skin barrier, dehydration, redness, and irritation.

• Ceramide Complex: Ceramides are essential natural components of the skin barrier. They help strengthen the skin, reduce water loss, keep the skin moisturized, and reduce irritation. Based on the product information we have, such as Ceramide Complex (Water/Oil Dispersible Powder), Cera-Flux V (Water Dispersible Ceramide Complex, 3 Types), and Ceracare™ Liposome-3 (Liposome Ceramide Complex, 3 Types), they all have properties that help restore the skin barrier, increase moisture, and reduce sensitivity and irritation.
• Vitamin B3 (Niacinamide): Niacinamide, or Vitamin B3, such as Safe-B3™ (Vitamin B3, Niacinamide), is a versatile ingredient that is very good for the skin. It helps boost the skin's natural ceramide production, strengthening the skin barrier, reducing water loss, reducing redness and inflammation, and also helps control oiliness, reduce the appearance of pores, and improve skin tone.

Instead of mixing them into your existing Ezerra lotion, which may destabilize the formula, especially if you are new to this, it's better to consider alternative approaches that are easier to control and safer for sensitive skin after acne treatment:

1. Use products specifically formulated with Ceramides and Niacinamide: Look for serums or moisturizers that already contain these ingredients and use them in conjunction with your Ezerra lotion. You could apply a serum with Ceramide or Niacinamide first, followed by your Ezerra lotion.
2. Try making a simple basic formulation yourself: If you are truly interested in making your own skincare, you could start with a simple basic formula using Ceramide Complex and Niacinamide in a compatible base, such as a basic serum base or cream base. This allows you to control the concentration and understand the mixing process better.

For your sensitive skin after acne treatment, strengthening the skin barrier with Ceramides and Niacinamide is the correct approach. However, you should start with low concentrations and observe your skin closely. If you experience stinging, redness, or irritation, you should stop using the product or reduce the concentration.
