It varies a lot. A 40-year-old I'm with looks like she's 25, but a 22 year-old-woman I'm with looks her age. Keep in mind you'll see a lot of makeup in these kinds of clips, and Asian women can be very good at using it, on top of cosmetic surgery being extremely normal. Also most women will take it off after you get home and before you fuck them. Eyebrows and eyelashes are the biggest giveaway,
All that said, they will tend to age better than us because of better diets and more exercise anyway.
