☀️ Is Your Sunscreen Throwing Off Your Hormones & Fertility?

When you’re trying to conceive or simply supporting your hormonal health, what you put on your skin matters just as much as what you put in your body. Most people don’t realize that conventional sunscreen may be silently disrupting your hormones—and that can impact your fertility.

Let’s break down what’s really in that bottle of SPF—and what you should be using instead.

🚫 The Toxic Truth About Sunscreen Ingredients

Many conventional sunscreens contain chemical UV filters that absorb into the skin—and some even enter your bloodstream within hours. The most concerning ingredients are:

• Oxybenzone (benzophenone-3) – a known endocrine disruptor linked to lower testosterone, estrogen imbalance, and disrupted ovulation.

• Octinoxate – can mimic estrogen in the body and disrupt thyroid hormone levels.

• Homosalate – accumulates in body fat and can interfere with estrogen, androgen, and progesterone.

• Avobenzone – degrades in sunlight and may form free radicals that damage cells.

These hormone-disrupting chemicals can:

• Suppress ovulation

• Impair egg quality

• Disrupt the delicate balance of estrogen and progesterone

• Interfere with thyroid function, which is crucial for conception and sustaining a healthy pregnancy

🌿 What to Look for in a Fertility-Friendly Sunscreen

Not all sunscreens are bad. In fact, mineral sunscreens are a safe, effective alternative that sit on top of the skin to block UV rays, rather than absorbing into your bloodstream.

Here’s what to look for:

✅ Active ingredients: Zinc oxide or titanium dioxide only

✅ Non-nano particles – to prevent absorption into the body

✅ No fragrance – artificial fragrance often contains phthalates, another hormone disruptor

✅ No parabens, sulfates, or PEGs

✅ Broad-spectrum SPF 30+
