Phase IV · Luteal
The luteal phase survival guide for your lips and skin
May 2026

Nobody talks about the luteal phase the way they should. It is the longest phase of the cycle — up to 14 days — and for many women it is the most challenging. The skin changes. The mood shifts. The body asks for something different. Here is what is actually happening, and how to care for yourself through it.
What happens during the luteal phase
The luteal phase begins the day after ovulation and lasts until the first day of your next period — roughly days 17 to 28. During this phase, the empty follicle that released the egg transforms into the corpus luteum, which produces progesterone. Progesterone rises significantly during the early luteal phase, then falls if pregnancy does not occur. Estrogen also rises briefly and then drops.
This hormonal choreography creates a very specific set of physical experiences. Progesterone stimulates the sebaceous glands, meaning your skin produces more oil — leading to the familiar pre-period breakouts, particularly around the chin and jaw. The drop in estrogen reduces collagen production and skin hydration, making lips drier and more sensitive as the phase progresses. Many women also experience bloating, fatigue, heightened emotional sensitivity and a strong instinct to slow down and withdraw from social activity.
These are not flaws or weaknesses. They are intelligent biological signals asking you to rest, nourish and prepare.
What your lips need during the luteal phase
As estrogen falls, your lips lose hydration more quickly. The increased skin sensitivity means fragranced products can suddenly cause irritation that they didn't cause during ovulation. Oil production increases, which paradoxically can lead to a feeling of congestion on the lip skin. What you need is balance — deep moisture without heaviness, calming without numbing, grounding without sedating.
Still Water was built for exactly this.
The ingredients in Still Water and why we chose them
Lavender oil is one of the most well-researched calming botanicals in existence. Applied to the skin, it reduces inflammation and soothes sensitivity. Its gentle scent — mild enough for the luteal phase — has been shown to support the nervous system too.
Arnica extract is a powerful anti-inflammatory that reduces redness and swelling, helping to calm any reactive skin around the lips during this phase.
Calendula is our most gentle ingredient — used for centuries to soothe the most sensitive, compromised skin. It repairs, calms and protects without any harshness whatsoever.
Marula oil is a lightweight dry oil rich in oleic acid, absorbed quickly and deeply into the lip skin without leaving a heavy residue. It grounds and nourishes without congesting.
The finish of Still Water is intentionally soft — a matte-satin rather than a gloss, because during the luteal phase your body is already turning inward. Your lip oil should too.
How to care for yourself during the luteal phase
Use Still Water as your daily lip oil from around day 17 until your period begins. Apply before bed as an overnight treatment. Reduce fragranced products across your whole routine during this phase, not just your lips. Rest more than you think you need to. Eat warm, nourishing foods. Move gently — walking, stretching, slow yoga. Say no to things that drain you without apology.
The luteal phase is not something to push through. It is something to move with. Still Water is simply here to make the moving a little more graceful.
Because stillness before the cycle begins again is not weakness. It is wisdom.
