Stretch marks from your first pregnancy 4 years ago and the new ones from your second are very common, resulting from skin stretching and hormonal changes that weaken collagen fibres, making skin more prone during repeat pregnancies. At 6 months postpartum, the newer pink or dark marks will gradually fade over 12-18 months with consistent care, though they rarely disappear fully. While breastfeeding, prioritise safe daily moisturising with gentle, fragrance-free creams containing hyaluronic acid or shea butter to improve hydration and texture, alongside a nutrient-rich diet high in vitamin C and zinc, and sun protection to prevent darkening. Avoid retinoids or other potent actives at present due to potential absorption risks during lactation. Once breastfeeding ends, consult a dermatologist for personalised options, such as microneedling (with precautions) or laser therapy to stimulate collagen and enhance results under medical supervision.

Fixderma Strallium Stretch Mark Cream can be used on stretch marks that are 4 years old. It may help reduce their appearance by improving skin texture and colour, but older marks usually respond more slowly and may not completely disappear. Results can vary depending on factors such as the age of the marks, skin type, and consistency of use, and some cases may require additional treatments. For best results, consulting a dermatologist is recommended.
