Beauty Tips For Body Care
Hi people! I would love some insight and advice on this product I’ve started using in the hopes of benefiting my skin in terms of reducing breakouts (most likely hormonal), cleaning pores and blackheads, achieving softer skin, and perhaps glowy skin. I only use it on my problem areas, so forehead, chin, nose and temples. It’s been 9 days of using it in the PM and it hasn’t improved anything and I just got a papule on my forehead :’) and in terms of texture it is not soft at all and made it feel a little rough. Is it supposed to help right away? I thought exfoliant would make skin soft and clean but I still have blackheads and pimple and I feel like it caused a rougher/drier texture.
