Hello and thank you for your question! We absolutely love DefenAge in our practice for many reasons, one being that it truly is suitable for every patient. Yes, an olive-skinned person can use DefenAge skincare. The brand is known for its Age-Repair Defensins® technology, which promotes skin rejuvenation by activating dormant skin cells. DefenAge products are generally non-irritating, free from harsh retinoids, and suitable for all skin tones, including olive skin. However, here are a few things to consider when trying new skincare: Hyperpigmentation risk: Olive skin is more prone to post-inflammatory hyperpigmentation (PIH). While DefenAge doesn't contain traditional exfoliating acids or retinol that might increase this risk, you should still patch-test new products. Hydration balance: Some olive-skinned individuals have combination or oilier skin. DefenAge formulations tend to be well-balanced, but if you have oily skin, you might prefer lighter products in their line. Sunscreen is key: Since DefenAge promotes cell turnover, always pair it with SPF to protect your skin from pigmentation and sun damage. I hope this helps!
