Skin Health in Pregnancy & Beyond

Pregnancy is a time of profound change and not just for your body, but for your skin. Shifts in hormones, circulation, metabolic and immune function can all influence how your skin behaves, often in unpredictable ways. Some people experience the famous “pregnancy glow,” while others battle new acne, dryness, sensitivity, melasma, or itchiness. Rising estrogen, progesterone, human chorionic gonadotropin (hCG), cortisol, and increased blood volume all influence the skin’s structure and function. These changes affect the epidermal barrier, sebaceous activity, melanocyte stimulation, dermal collagen, and cutaneous blood vessels, which is why skin can look dramatically different from trimester to trimester and again after delivery. Understanding what’s happening (and which products are safe - stay tuned for part 2) helps you keep your skin healthy while protecting the safety of your baby.

Second Trimester (Weeks 13–27): The “Glow” and Pigment Shifts

The second trimester is often when people notice the so-called “pregnancy glow.” This is largely due to increased blood volume (up to 40–50%), improved peripheral circulation, and estrogen-driven vasodilation, which enhances nutrient and oxygen delivery to the skin. The dermis becomes more hydrated, and many experience smoother, brighter-appearing skin during this phase.

However, increased estrogen and progesterone also stimulate melanocytes (pigment-producing cells in the basal layer of the epidermis). This can lead to melasma (chloasma), darkening of the areolae, linea nigra, and post-inflammatory hyperpigmentation, especially with sun exposure. UV radiation amplifies these effects, making daily sun protection particularly (aka a non-negotiable) important during pregnancy.

Sebum production may remain elevated, so acne-prone skin can persist or fluctuate into the second trimester for some. Conversely, some individuals experience improvement in inflammatory skin conditions during this trimester due to relative hormonal stabilization.

Third Trimester (Weeks 28–40): Stretching, Vascular Changes & Dryness

As the body prepares for delivery, mechanical and hormonal factors increasingly affect the skin. Rapid stretching of the skin, particularly over the abdomen, breasts, hips, and thighs, can disrupt dermal collagen and elastin fibers, contributing to the development of striae gravidarum (stretch marks). Elevated cortisol and estrogen reduce fibroblast activity and collagen integrity, making the skin more vulnerable to tearing at the dermal level. Stretch marks develop in two stages. The early stage, striae rubrae, appears pink, red, or purple and reflects active inflammation and skin stretching. These marks may feel itchy and can be flat or slightly raised. Over time, they transition into striae albae, the mature stage, which looks lighter, white, or silvery with a thinner, scar-like texture. This process can take months to years. While they typically fade and soften within one to two years postpartum, they generally do not disappear completely.

Increased blood volume and venous pressure may lead to spider veins, varicosities, facial flushing, and worsening rosacea. Some individuals also experience increased itching (pruritus) due to skin stretching, dryness, or changes in bile flow. Barrier function may be compromised, leading to transepidermal water loss (TEWL) and a greater need for barrier-supportive skincare.

Sleep disruption, reflux, and altered digestion in late pregnancy can further influence skin health through stress-related cortisol shifts, impaired detoxification, and nutrient absorption challenges.

Postpartum: Hormonal Withdrawal & Skin Reset

After delivery, estrogen and progesterone levels drop rapidly, which can significantly affect the skin. Many experience postpartum acne, increased dryness, sensitivity, or flare-ups of eczema and rosacea as sebaceous activity recalibrates and the skin barrier readjusts. Hair shedding (telogen effluvium) often occurs alongside skin changes, reflecting broader shifts in connective tissue and follicular cycling.

Sleep deprivation, elevated stress hormones, blood loss during delivery, and nutrient depletion, particularly iron, zinc, essential fatty acids, and B-vitamins, can slow skin repair and impair barrier recovery. For those breastfeeding, ongoing hormonal demands may prolong dryness and/or sensitivity. Pigmentation such as melasma may fade gradually over months but can for many women, it can persist and is amplified further without adequate sun protection.

Every pregnancy and how skin changes tells a different story.

Skin changes during pregnancy and postpartum are universal, but how they show up, and how intense they feel, is deeply individual. There is no single “normal.” Pregnancy is a season of rapid physiologic change, and your skin is a visible reflection of the shifts happening beneath the surface. The most important approach is one that meets you where your skin is now, while aligning with your personal skin health goals and the safety of your growing baby.

With informed guidance and evidence-based care, it is absolutely possible to support resilient, healthy, glowing skin throughout pregnancy. In Part 2 of this blog, I’ll break down the safety and effectiveness of common skincare ingredients and products so you can make confident, informed choices. Working alongside a qualified healthcare provider or skin professional ensures your routine supports not just your skin, but your whole body and your baby, through every stage of pregnancy and beyond.
