Three things cause acne: overactive sebaceous glands (oils), abnormal skin cell turnover, and the rapid proliferation of bacteria that cause blemishes.
Acne affects people of all ages. It is recommend to treat acne early, especially during the first year of acne development. Early acne treatment has many benefits. Besides preventing the development of new scars, it also eliminates some pre-existing scars. As we age, acne scarring can become even worse. Our skin requires the production of new collagen and elastin to repair acne scars. As we age, collagen regeneration in our skin decreases. Ageing skin requires more stimulation to produce enough collagen to smooth scarring.
