The concept of Microneedling is based on the skin’s natural ability to repair itself whenever it encounters physical damage such as cuts, burns and other abrasions. Immediately after an injury to the skin, our body reuses the damaged collagen and the elastin fibres as well as other damaged skin components to produce new ones.
Microneedling causes micro controlled trauma to the skin and initiates the self-repair mechanism by creating micro-“injuries” in the skin which triggers new collagen synthesis. The result is having a smoother, firmer and healthier scalp. The process is carried out with a Micro needle stick that is filled with numerous tiny pins that will penetrate the upper layers of the skin.This process has two major benefits. It effectively stimulates collagen formation and at the same time provides a clear channel for topical serums to be absorbed more effectively through the top layer (epidermis) of scalp.

As your Trichologist performs the microneedling , it is making pin point punctures into the dermis – most of which are simply temporarily opening your pores for deeper penetration of the medicine. The absorption of the medicine is faster and your body perceives this as damage, which triggers the release of growth factors that, in turn, stimulate the production of elastin and collagen.
By persistently triggering this healing process, you encourage your body to keep repairing until the job is done. Microneedling may be conducted safely on all colours of skin and all types of skin. The epidermis and melanocytes in the basal area are not damaged, so there’s no possibility of post inflammatory condition.
But it is important to take past history of the client as microneedling is contraindicated in following conditions:-
- Active bacterial, viral or fungal infections
- Keloid or raised scars
- Active pustular acne
- Scars less than 6 months old
- Raised moles or warts
- Strong antihypertensive medication, Anti coagulants , Cardiovascular medication
- Actinic (solar) keratosis
- Surgery in the past 6 months.
