With age, the outer layer of skin (epidermis) starts to thin; even though the number of cell layers remains unchanged, this can result in a variety of aesthetic changes, including: • Decrease in number of melanocytes (pigment-containing cells); remaining melanocytes increase in size • Skin looks thinner, paler and clear (translucent) • Hyperpigmentation, including age spots (liver spots) • Reduction in skin's strength and elasticity (elastosis) • Blood vessels of the dermis become weaker; this leads to: • Bruising • Bleeding under the skin (senile purpura) • Cherry angiomas • Sebaceous glands produce less oil • Skin has less insulation and padding • Sweat glands produce less sweat • Growths such as: • Skin tags • Warts • Brown rough patches (seborrheic keratoses) • Pinkish rough patches (actinic keratosis) • Deeper wrinkles and lines in the forehead • Skin folds around the jaw-line • Fat loss in the central face • Excess skin laxity • Visible blood vessels from thinning of skin
