## Description

Product Description Simple Smooth+ 10% Niacinamide (Vitamin B3) Serum is an advanced skin care solution designed to achieve visibly smoother, more even-toned skin in just 2 weeks. Powered by SkinTwin* science, this revolutionary skin-mimicking technology works with your skin’s biology, mirroring its natural repair processes to improve skin texture and tone. Formulated with 10% niacinamide, our face serum promotes cell turnover** and helps restore your skin’s natural, even tone. Complemented by 1% vitamin B5, it hydrates your skin for a softer, smoother feel, while 1.5% vegan glycerin protects against dryness to improve skin elasticity. Our niacinamide serum is clinically proven to deliver results. Users reported visible improvements in skin radiance within just 1 week, and a refreshed and hydrated feel with every use. 90% agreed their skin appeared more glowing and felt velvety soft. It’s your solution to achieving skin that feels and looks beautifully smooth and even. Shake, drop, dab – it’s that simple. After using a cleanser, apply our face serum alone, or mix a few drops into your favourite moisturiser. Oh, and it’s fab under makeup too. Try cocktailing it with Simple Hydrate+ 3% Hyaluronic Acid + Vitamin B5 Serum. It’s best not to combine niacinamide with vitamin C, as these two antioxidants play better when used separately. If you’d like to use both, we recommend applying our Glow+ 10% Vitamins C + E + F Serum in the morning and then using the niacinamide serum as part of your nighttime routine. *SkinTwin is trademarked. **Within the stratum corneum.

## Questions & Answers

**Q: Looking for reviews on these eye drops and there is nothing but reviews about skin creams ???**
A: Sorry you need to listen to this. These are not eye drops, this is a skin serum and should never be used anywhere near the eyes and definitely not in them. Hyaluronic acid is what it says it is, would you put an acid in your eyes? Look for something that says it's eye drops, safe for eyes.

**Q: Any fragrance??**
A: Hi, there is no fragrance from this product

**Q: Isn't it deceiving to advertise 3% hyaluronic acid & b5 when in fact it's only 0.5% hyaloronic acid and 2.5% b5?? why word it like this?**
A: I agree, but it's a really good serum nonetheless and I recommend it.

**Q: Does this contain salicylic acid?**
A: It does not contain salicylic acid.

### ⭐⭐⭐⭐ I’m glowing!!
*by C***D on 3 July 2025*

I’ve been using the Simple Niacinamide Serum for a few weeks now, and it’s honestly such a great addition to my routine. It’s super lightweight, absorbs quickly, and doesn’t leave any sticky residue — perfect for layering under moisturiser or makeup. My skin looks noticeably calmer and brighter, and I’ve seen fewer breakouts and less redness around my nose and chin. I also really appreciate that it’s fragrance-free and made for sensitive skin — no irritation at all, which is rare for my skin!
