Yes, the difference in wrinkling between types of complexions is a documented phenomenon; see p. 435 of Wilhelm et al., Bioengineering of the skin: skin imaging and analysis (on Googlebooks):

[E]xpression of facial wrinkling increased commensurate with age in all racial groups. There were, however, differences in relative expression between racial groups, with wrinkling increasing in the order East Asians < Latinos = African-Americans < Caucasians.

Interestingly, it isn't just amount of melanin or skin darkness that determines amount of wrinkling, since lighter-skinned East Asians tend to express less wrinkling than darker-skinned African-Americans. This article (http://ibmi.mf.uni-lj.si/acta-apa/acta-apa-02-3/derma3-1cl.html) notes,

A unique study of over 3000 people from five ethnic groups (Africa, American, East Asian, Caucasian, Indian Asian and Latino) of different ages has revealed age-dependent changes of the skin (wrinkles, hyperpigmentation and pores). The mean fraction of the face area covered with wrinkles is significantly smaller in African Americans than in Caucasians, but East Asians have the smallest wrinkled area at any given age. The authors suggest that racial differences in other genetic factors besides skin pigmentation, such as DNA repair, are important in determining the development of skin wrinkles. African Americans have more hyperpigmented spots and facial pores than other racial groups. Caucasians have significantly les well hydrated skin than African Americans, East Asians and Latinos (191). The relationship between skin phototype and deep and fine wrinkle scores on the faces of 230 Japanese subjects shows that sunlight-sensitive subjects have deeper wrinkles.(192).

The same article also gets into the biological causes of wrinkling:

Principal causes of wrinkling are ageing and excessive exposure to UV rays. Wrinkles are the expression of the accumulation of modifications at different levels of the skin. Development of so-called fine wrinkles begins to take place in the thirties, reaching a peak in the fifties, while deep wrinkles increase in the fifties. Little is known about the exact histological changes underlying wrinkle formation. Changes in collagen type I, III, type IV and VII at the DEJ have been recorded (157-160). Collagen VI, concentrated in the papillary dermis immediately below the dermal-epidermal junction is similar in photoprotected and photoaged skin (159). Some fibroblasts which are accumulating damages are less stimulated by surrounding ascorbic acid, resulting in a decrease of collagen and a loss of dermis density. Very recently, in aged fibroblasts from photoexposed zones, a decrease of the intracellular transport of pericellular ascorbic acid has been proposed in wrinkle formation and ellagic acid derivatives have been proposed to overturn the phenomenon (161; Marc Dumas, personal communication).

I hope that paragraph conveyed more to you than it did to me! Seriously, that looks like the place to start if you want information about skin ageing.
