Black Stretch Marks During Pregnancy

They commonly develop as the abdomen, breasts, hips, or thighs expand. Their colour often becomes less noticeable after pregnancy, although the lines may not disappear completely.

Stretch marks form when rapid tissue expansion changes collagen and elastin within the deeper skin. New marks may be raised, itchy, reddish, purple, brown, or very dark before gradually becoming flatter and lighter.

Pregnancy-related hormonal changes can also increase pigmentation, making new lines appear darker than the surrounding skin. Colour alone does not show that a mark is infected or dangerous.

Apply a plain fragrance-free moisturiser when the skin feels dry or tight, avoid vigorous scrubbing, and choose loose clothing if friction worsens itching. Moisturisers may improve comfort but cannot reliably prevent the underlying skin change.

Do not start a strong lightening product, retinoid, peel, or procedure while pregnant without checking its ingredients and suitability with your obstetric clinician or dermatologist. Procedures such as microneedling or laser treatment are generally discussed after pregnancy, once the skin has settled and feeding considerations have been reviewed.

Contact your maternity team promptly if severe widespread itching occurs, particularly on the palms or soles, even when there is little visible rash. That pattern needs assessment because it is not explained by stretch marks alone.

Seek a skin examination for rapidly spreading painful areas, warmth, pus, open sores, marked swelling, fever, or a new rash with blisters. A clinician can distinguish ordinary striae from irritation, infection, or another pregnancy-related skin condition.

Ask whether the appearance fits pregnancy stretch marks, which moisturiser ingredients suit your skin, and whether your itching needs pregnancy-specific tests. If the marks remain bothersome later, ask when it would be appropriate to discuss procedures and what improvement is realistic for your skin tone.
