Skincare for Acne
Acne is caused when the pores become blocked by an oil produced by the sebacious gland called Sebum. Cellular debris and sebum becomes trapped, bacteria multiply, feed of the sebum and multiply further. The result is a comedome or a spot.
Acne can take many forms from pimples, pustules, blackheads, whiteheads to cystic.
TYPES OF ACNE
Non-inflammatory acne
Blackheads and whiteheads (aka open and closed comedones) occur when a plug made up of sebum and dead skin cells can be seen inside a follicle (pore), but does not cause any inflammation or redness.
Blackheads: If the plug enlarges and stretches the pore, it is referred to as a blackhead. Blackheads aren’t trapped dirt. Rather, the dark colour is a build-up of melanin and oxidized oil.
Whiteheads: When a thin cover of skin traps the plug, it prevents the oil from oxidizing. This keeps it white and creates a whitehead.
Inflammatory acne
When follicles are blocked by sebum and skin cells, the follicular wall is under pressure. If the pressure is great enough, then the follicle wall will break and the contents will spread into the surrounding skin.
When your immune system responds to this bacteria and sebum, inflammatory acne occurs. The degree of inflammation determines the size and redness of an acne lesion.
Papules: Pink or red bumps without a white or yellow centre.
Pustules: Red bumps with a white or yellow centre of pus. Pustules are formed when the plug inside a pore traps oil and bacteria, which draws white blood cells to the area to fight infection. Pus is made up of dead white blood cells.
Cysts and nodules
Larger (and often painful) acne lesions that extend into the deeper skin layers. Cysts and nodules can last for months, destroy the follicle and lead to permanent scars.
Individuals with this type of acne should see a dermatologist for treatment.
Proliferation of P. acnes bacteria and consequent inflammation
It is important when treating Acne to address the oil, the bacteria and the the cellular turnover by looking at ingredient that target this and good exfoliation to prevent dead cells blocking the pores.
Salicylic acid and Oligopeptide 10 manage bacteria, exfoliates inside the pore, can penetrate oil and has anti inflammatory properties.
Hinokitiol controls P Acne bacteria
Retinol improves cellular turnover, this can be found under the products for ageing tab.
Resveratrol provides antioxidant protection for cells.
Zinc oxide protects against physical UVA and UVB.
