40-year-old Ou Hui's limit is still Qi Dan

1, Ouhui Extreme is more suitable for people with dry skin, because the moisturizing degree is higher than that of TianQi Dan, which can provide better moisturizing effect for the skin.

2. Ouhui pays great attention to repair and anti-aging, which can promote the regeneration of skin stem cells, enhance the immune effect of skin, effectively fight against skin aging, and make skin smoother and firmer. Tianqidan is not as good as Ouhui in repair and anti-aging. So Ou Hui is excellent.
