Our hair growth inhibitor serum has been clinically tested to deliver measurable results:

Reduces hair regrowth

Weakens hair follicles

Extends time between hair removal sessions

Improves skin texture and smoothness

Gentle formula suitable for sensitive skin

Our Cyperus Rotundus Skin Serum targets hair follicles through localized androgen blocking. Active compounds inhibit the 5α-reductase enzyme and block androgen receptors directly at the follicle level, reducing DHT production and preventing hair growth activation.

This mechanism works on all hair colors - including white and blonde hair that laser cannot treat - by targeting hormone pathways rather than pigment. The formula acts locally at the application site without systemic hormonal effects.

Hair growth slows within 1-2 weeks as follicles receive reduced growth signals, resulting in progressively finer, sparser regrowth with continued use.

Massage a few drops of Shrene Cyperus Rotundus Oil onto clean skin after hair removal. Let it absorb fully then go about your day—no rinsing, no waiting.

It works by targeting regrowth at the root while soothing skin irritation, all in less than 5 minutes.

Our Cyperus Rotundus Skin Serum can be safely used on all body areas including face, underarms, bikini line, legs, and arms. For facial use, avoid the eye area.

Our Cyperus Rotundus Skin Serum is formulated with carefully selected natural botanicals that work gently on your skin without disrupting hormonal balance.

The base features nourishing Olive Oil and Vitamin E to moisturize and repair skin post-hair removal, preventing irritation and razor bumps. Peppermint Extract provides a cooling, soothing sensation while Lemon Extract naturally brightens and evens skin tone.

Shrene is safe to use for women with hormonal conditions because it workslocallyon the skin surface and hair follicles. Our botanical serum does not enter the bloodstream or affect your body's hormone levels. The Cyperus Rotundus and other natural ingredients work directly where applied, targeting only the hair follicle structure in that specific area. This localized approach means it won't interfere with your natural hormonal balance, making it safe for use during pregnancy, while managing PCOS, or during menopause.
