The “+” symbol indicates that the skin has a significant sebaceous activity. Sebum, naturally produced by the sebaceous glands located in the dermis, forms with sweat the hydrolipidic film, this thin protective layer that limits water evaporation and forms the first barrier against external aggressions. In VE(+) skin types, this lipid protection is present in sufficient, even excessive, amounts, giving the skin a shinier appearance, especially in the T-zone (forehead, nose, chin). This sebaceous gland hyperactivity is driven by various mechanisms, but is mainly hormonally controlled. Indeed, skin that produces a lot of sebum often has high circulating androgen levels, notably dihydrotestosterone, and an increased sensitivity to these hormones.
VE(+) skin is not lacking in natural protection. However, this abundance of sebum does not equate to balance. When produced in excess, sebum can accumulate in pores, mix with dead skin cells, and promote a comedogenic environment. This results in uneven skin texture, enlarged pores, and an increased risk of imperfections, even in adulthood. Moreover, this situation can be exacerbated by aging: with age, the pores tend to dilate due to dermal laxity, making the skin’s surface appear less smooth.
The “+” symbol indicates skin that is naturally rich in lipids but prone to imbalances: enlarged pores, excess shine, occasional blemishes, and texture irregularities.
