Particularly in the second half of pregnancy, this often leads to the development of so-called <b>pregnancy marks<\/b> \u2013 medically known as <i>striae distensae<\/i> or <i>striae gravidarum<\/i>, but also commonly referred to as stretch marks.<\/p>\n<p>These occur when the elasticity of the connective tissue is overstretched. Between 50 and 90% of all pregnant women experience these tears in the connective tissue \u2013 mainly on the abdomen, breasts, hips, and thighs. Initially, they appear reddish to bluish, but fade over time and take on a pearly, skin-like tint.<\/p>\n<p>Stretch marks can also occur outside of pregnancy, for example due to rapid weight gain or hormonal changes. Why they occur in some women and not in others is not yet fully understood. Influencing factors include:<\/p>\n<ul>\n<li>Genetic predisposition<\/li>\n<li>Firmness of the connective tissue<\/li>\n<li>Hormone-induced loosening of the skin<\/li>\n<li>Size of the baby<\/li>\n<li>Multiple births<\/li>\n<\/ul>\n<p>While the skin often regenerates well in younger women, the risk of permanent marks increases with repeated pregnancies. Many women affected find these changes disturbing, which is why there is such a wide range of care products available for prevention and treatment.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<h2>Pregnancy care oils \u2013 effects and selection<\/h2>\n<p>Particular attention is paid to <b>care oils<\/b> that promise to prevent or reduce stretch marks.<\/p>\n<p>Even though many causes cannot be influenced, skin care can still have a supportive effect \u2013 especially <b>preventively<\/b>. It is helpful to avoid excessive weight gain, stay active regularly, and stimulate the skin through pinch massages, showers, and targeted care.<\/p>\n<p><b>Care oils, lotions, or creams<\/b> contribute to the suppleness of the skin and promote well-being. Although they do not guarantee stretch mark-free skin, regular use can make the skin more elastic and thus have a preventive effect.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<h2>What should pregnant women look for in care products?<\/h2>\n<p>The <b>purity of the ingredients<\/b> is particularly important. Good oils do not require preservatives, do not contain emulsifiers or silicones that are difficult to break down \u2013 they are water-free and usually very well tolerated.<\/p>\n<p>The following should be avoided:<\/p>\n<ul>\n<li>allergenic fragrances (often at the end of the INCI list)<\/li>\n<li>petroleum derivatives such as <i>Paraffinum liquidum<\/i><\/li>\n<li>synthetic preservatives<\/li>\n<\/ul>\n<p><b>Ideal:<\/b> certified organic oils. However, high-quality conventional oils are also generally suitable \u2013 as long as they are formulated to be skin-friendly.<\/p>\n<p>Typical base oils in care products for pregnant women are:<\/p>\n<ul>\n<li>Sunflower oil<\/li>\n<li>Almond oil<\/li>\n<li>Soybean oil<\/li>\n<li>Wheat germ oil<\/li>\n<li>Avocado oil<\/li>\n<li>Sesame oil<\/li>\n<li>Safflower oil<\/li>\n<li>Caprylic\/capric triglyceride (neutral oil from coconut oil)<\/li>\n<\/ul>\n<p>These oils have a moisturizing effect, smooth the skin, are well tolerated, and are quickly absorbed.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<h2>How effective are skin care oils against stretch marks?<\/h2>\n<p>One point of criticism remains that many products are based solely on empirical values \u2013 well-founded clinical studies are rare. Nevertheless, there are individual <b>active ingredients with proven potential<\/b> for preventing or reducing stretch marks.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<h2>Overview: Ingredients for prevention and care<\/h2>\n<p>In alphabetical order:<\/p>\n<p><strong>Aloe vera (Aloe Barbadensis Leaf Extract)<\/strong><\/p>\n<p>Moisturizing, regenerating \u2013 small studies suggest a protective effect against stretch marks.<\/p>\n<p><strong>Avocado oil (Persea gratissima)<\/strong><\/p>\n<p>Rich in vitamins E and A and phytosterols, promotes wound healing and skin elasticity.<\/p>\n<p><strong>Baobab oil (Adansonia Digitata Seed Oil)<\/strong><\/p>\n<p>Traditionally used in Africa for skin care \u2013 smoothes and strengthens connective tissue.<\/p>\n<p><strong>Centella Asiatica (Gotu Kola)<\/strong><\/p>\n<p>Scientifically proven: promotes collagen formation, improves scar healing, reduces stretch marks.<\/p>\n<p><strong>Pomegranate Extract (Punica granatum)<\/strong><\/p>\n<p>Strong antioxidant, promotes skin regeneration.<\/p>\n<p><strong>Rosehip seed oil (Rosa canina)<\/strong><\/p>\n<p>Rich in vitamin C, promotes healing and smoothing.<\/p>\n<p><strong>Cocoa butter (Theobroma Cacao Seed Butter)<\/strong><\/p>\n<p>Moisturizing, makes the skin supple \u2013 with good water-binding capacity.<\/p>\n<p><strong>Jojoba oil (Simmondsia Chinensis)<\/strong><\/p>\n<p>Absorbs well, protects against moisture loss.<\/p>\n<p><strong>Coconut oil (Cocos Nucifera Oil)<\/strong><\/p>\n<p>Improves the skin barrier and is ideal for massages.<\/p>\n<p><strong>Cornflower extract (Centaurea cyanus)<\/strong><\/p>\n<p>Antioxidant, skin-strengthening.<\/p>\n<p><strong>Macadamia oil (Macadamia Terniflora Seed Oil)<\/strong><\/p>\n<p>Nourishing and smoothing \u2013 promotes scar healing.<\/p>\n<p><strong>Almond oil (Prunus Amygdalus Dulcis)<\/strong><\/p>\n<p>Skin-friendly, particularly mild \u2013 also suitable for baby skin.<\/p>\n<p><strong>Manilkara Multinervis Leaf Extract<\/strong><\/p>\n<p>Protects against elastin breakdown, strengthens the skin structure.<\/p>\n<p><strong>Evening primrose oil (Oenothera biennis)<\/strong><\/p>\n<p>Promotes skin renewal and activates the metabolism.<\/p>\n<p><strong>Olive Oil (Olea europaea)<\/strong><\/p>\n<p>Classic massage oil, moisturizing, smoothing.<\/p>\n<p><strong>Peptides (e.g., Copper Tripeptide-1, Acetyl Tripeptide-30 Citrulline)<\/strong><\/p>\n<p>Regenerating, anti-inflammatory, promote collagen and elastin formation \u2013 with the potential to reduce stretch marks.<\/p>\n<p><strong>Sea buckthorn oil (Hippophae rhamnoides)<\/strong><\/p>\n<p>Antioxidant, strengthens skin tissue.<\/p>\n<p><strong>Horsetail (Equisetum Arvense)<\/strong><\/p>\n<p>Rich in silicic acid \u2013 strengthens connective tissue, improves skin elasticity.<\/p>\n<p><strong>Sloe blossom oil (Prunus spinosa)<\/strong><\/p>\n<p>Astringent, skin-firming.<\/p>\n<p><strong>Soybean oil (Glycine max)<\/strong><\/p>\n<p>Inhibits elastin-degrading enzymes, stimulates elastin formation.<\/p>\n<p><strong>Sunflower oil (Helianthus annuus)<\/strong><\/p>\n<p>Strengthens the skin barrier, reduces water loss.<\/p>\n<p><strong>Grape seed oil (Vitis vinifera)<\/strong><\/p>\n<p>Promotes healing, smoothing, antioxidant.<\/p>\n<p><strong>Wheat germ oil (Triticum Vulgare Germ Oil)<\/strong><\/p>\n<p>Rich in vitamin E \u2013 supports skin regeneration.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<h2>Conclusion: Natural care for greater well-being<\/h2>\n<p>Stretch marks cannot be completely prevented \u2013 but targeted care can reduce their appearance and significantly improve the feel of the skin.<\/p>\n<p><b>Regular use<\/b> of skin-friendly, preferably natural care oils and massages is key.
