The key thing is you don't have to throw out everything. Retinoids are the big no-go - those need to pause for the duration. Salicylic acid at low concentrations (like 0.5-2% in a cleanser or toner you rinse off) is generally considered safer than high-dose treatments, though some doctors prefer to avoid it entirely just to be cautious. Azelaic acid is actually a solid alternative that tackles both breakouts and irritation without the pregnancy concerns. Niacinamide, vitamin C, and hyaluronic acid are all fine and can help with both the breakouts and dryness you're dealing with. Glycolic acid is another option - most derms seem more comfortable with it than salicylic acid, though again some prefer you skip actives altogether.
The pregnancy-safe brands aren't inherently better, just formulated to avoid the flagged ingredients. What matters more is that your skin is actually going haywire right now because of hormones, so what worked for years might just need tweaking. Focus on a gentle cleanser, solid moisturizer, and sunscreen (crucial). If you're breaking out and dry at the same time, that often means your barrier is angry - sometimes scaling back to basics and letting it recover helps more than adding targeted treatments. Chat with your OB or a dermatologist who has prenatal experience; they can give you the green light on specific products you already own instead of you guessing.
