## Questions & Answers

**Q: Most retinol is yellow in color. Why is serum not yellow if it has 2.5% retinol**
A: Take a glass and fill it with 100% plain, crystal clear water. If you add 2.5% of ANYTHING to it, it's not going to change the color of the glass of water. 2.5% sounds like a significant amount when you're thinking in terms of retinol, but 2% of anything is virtually invisible unless it is pure pigment or has an intense, deep dark color in nature, like the copper ions in a copper peptide serum.

**Q: How much pure retinol is in this product?**
A: 2.5%

**Q: "Is this for aging wrinkles and under eye bags and dark circles**
A: Retinoid Facial Serum designed to complement skin's renewal procedure and decrease the advent of excellent traces and wrinkles. Thanks to its ability to boost skin-building compounds, Retinol is has long been the anti-wrinkle go-to! To maximize the anti-aging benefits even further, we added hyaluronic acid powder and Vitamin E to promote collagen production and smooth fine lines.

**Q: Does the bottle come sealed?**
A: Yes

### ⭐⭐⭐⭐ Refreshing serum with good consistency and texture on skin.
*by E***F on 3 April 2026*

I really have not seen yet results as I am still barely a week in using it, but I liked the consistency and texture of it in my skin. It layers well with my make-up. It gets absorbed easily in the skin. It has a neutral smell, it doesn't smell funny.
