Overall contribution of the set of polymorphisms that define a genotypic group on skin properties involved in aging

Genetic cluster	Skin properties
	Antioxidant capacity	Skin elasticity	Skin hydration
				1	0	−2	0
2	−3	0	+1
3	0	0	+1
4	−1	+2	0
5	−1	0	0
6	−1	−1	0
7	−1	+1	0
8	−6	+1	0
9	+1	+1	0
10	+3	−3	−1

Notes: Only effects of single nucleotide polymorphisms with a contribution over 75% to the genetic cluster definition were considered. Positive or negative integers show the magnitude of the added effects of SNP variants on each skin property for each genetic cluster.
