Abstract
INTRODUCTION:
Acne scars can cause emotional and psychosocial disturbance to the patient. Various modalities have been used for the treatment of acne scars like punch excision, subcision, peels, microdermabrasion, unfractionated and fractioned lasers. The latest in the treatment armamentarium is microneedling. Acne scars commonly coexist with postinflammatory hyperpigmentation.
A combination of microneedling and glycolic acid (GA) peels was found to give excellent results in the treatment of such scars. The aim was to study the efficacy of a combination of microneedling with glycolic peel for the treatment of acne scars in pigmented skin.
METHOD:
Thirty patients in the age group of 20-40 years with atrophic box type or rolling scars with postinflammatory hyperpigmentation were chosen for the study. Two groups were made. The first group comprised of 30 patients in whom only microneedling was performed once in 6 weeks for five sessions. In the second group of 30 patients, a combination of microneedling and 35% GA peels was carried out. Patients from both groups were evaluated on the basis of Echelle d'Evaluation clinique des Cicatrices d'acné classification.
RESULTS:
Based on the objective scoring and its statistical analysis, there was significant improvement in superficial and moderately deep scars (grade 1-3). There was also improvement in skin texture, reduction in postacne pigmentation in the second group.
CONCLUSION:
Microneedling is a simple, inexpensive office procedure with no downtime. It is safe in Indian skin (skin types III-IV). The combined sequential treatment with GA peel caused a significant improvement in the acne scars without increasing morbidity.

hahah.jojoba lavender Rosemary Thymian grape seed like many afro american women using To regrow hair .maybe i ll get such big dark hair too LoL
Does skin shedding decreases with more rolling sessions ?going hard with my 1,5 and nearly no shed
Not going hard enough! LOL.. We all differents.. really tough to say.. You are plunging yourself into the essentials oils crap! you crazy! Lavender smells like my grand ma lingerie!

Abstract
Androgenetic alopecia (Androgenetic Alopecia) is a dihydrotestosterone (DHT)-mediated process, characterized by continuous miniaturization of androgen reactive hair follicles and accompanied by perifollicular fibrosis of follicular units in histological examination. Testosterone (T: 10(-9)-10(-7) M) treatment increased the expression of type I procollagen at mRNA and protein level. Pretreatment of finasteride (10(-8) M) inhibited the T-induced type I procollagen expression at mRNA (40.2%) and protein levels (24.9%). T treatment increased the expression of transforming growth factor-beta 1 (TGF-beta1) at protein levels by 81.9% in the human scalp dermal fibroblasts (DFs). Pretreatment of finasteride decreased the expression of TGF-beta1 protein induced by an average of T (30.4%). The type I procollagen expression after pretreatment of neutralizing TGF-beta1 antibody (10 microg/ml) was inhibited by an average of 54.3%. Our findings suggest that T-induced TGF-beta1 and type I procollagen expression may contribute to the development of perifollicular fibrosis in the Androgenetic Alopecia,
and the inhibitory effects on T-induced procollagen and TGF-beta1 expression may explain another possible mechanism how finasteride works in Androgenetic Alopecia.
