Almost everything can influence skin type, which is why it can be so tricky to attribute a single skin type to what you see on your face. Both external and internal elements can and do impact the way your skin looks and feels. To effectively evaluate your skin and determine the correct skin-care routine, here are some of the factors that need to be considered:

Internal Influences:

• Hormonal changes (pregnancy, menopause, menstrual cycle, and more all cause skin conditions to fluctuate from oily to breakouts, skin discolorations, and dryness)
• Skin disorders (rosacea, psoriasis, dermatitis, with each one posing its specific concerns)
• Genetic predisposition of skin type (oily versus dry, prone to breakouts, sensitive skin)
• Smoking (cause of necrotic skin that cannot be corrected by skin-care products)
• Medications you may be taking (some birth-control pills can increase oily skin and breakouts while other types can actually improve the appearance of acne)
• Diet (there is research showing a diet high in antioxidants and omega-3 and omega-6 fatty acids can improve the appearance of skin)
