I would take @ggpetrov ‘s advice and drastically reduce the % of retinyl palmitate.

For two reasons: it does cause a sticky feel which is exacerbated by it’s slower absorption rate, and it might not be safe at that %.

The second reason is based on SCCS’ opinion which says “- via face cream at the maximum concentration of 0.3% may lead to daily systemic dose of 1185 IU for an adult. This exposure could constitute up to 24% of the UL of 5000 IU/day of Vitamin A. Therefore, the SCCS considers that the use of Vitamin A in face cream products per se is safe.” https://health.ec.europa.eu/publications/vitamin-retinol-retinyl-acetate-retinyl-palmitate_en

Even if you’re not in Europe, you’re using 2% which is 6.(6) times higher than 0.3%=> which gives a daily systemic dose way higher than the recommended 5000 IU/day (7900 UI)- that is if your costumer does not eat anything containing vitamin A, which is highly improbable. That could prove a dangerous daily systemic dose for any adult, healthy or not.
