Agnus Castus for Hormonal Acne

Hormonal acne often flares around the jawline and chin in the week or two before a period. One herbal option sometimes used for this cyclical pattern is Agnus Castus (Vitex agnus-castus). It can be helpful for some women, but it’s not suitable for everyone.

What it is

Vitex is traditionally used for menstrual-cycle related symptoms, especially those linked to the luteal phase (after ovulation). It may influence hormonal signalling via the pituitary gland and can affect prolactin and the oestrogen–progesterone balance.

When it may help acne

Vitex is most relevant when acne is clearly cyclical and paired with PMS-type symptoms such as:

-Breast tenderness 
-Mood changes before a period 
-Bloating 
-Spotting before a period 

If acne is persistent all month, Vitex may not be the best first step.

Dr. Vogel Agnus Castus

Dr. Vogel is a popular herbal brand in the UK. If you choose a product like this, follow the label directions carefully and avoid combining multiple hormone-active supplements at the same time unless supervised.

How to take it (expectations)

Vitex works gradually. A fair trial is usually 8–12 weeks (often 2–3 cycles), taken consistently each day (commonly in the morning).

Stop and reassess if your cycle becomes more irregular, your mood worsens, or symptoms feel “off.”

Who should avoid it or get medical advice first

Please seek medical advice first if any apply:

-Pregnancy or breastfeeding 
-Hormonal contraception 
-HRT or prescribed hormones (including progesterone) 
-Fertility medications (e.g., letrozole, clomiphene) or IVF support 
-Hormone-sensitive conditions (breast/uterine/ovarian) 
-Pituitary disorders or prolactin concerns
