Pro Vitamin D provides antioxidant protection to help defend skin from stressors and free radicals which can leave skin dehydrated and also lead to premature signs of aging. It also helps support ceramide production which supports sustained hydration.
By choosing formulas enriched with this ingredient, you’re boosting your skin’s environment-defense system.

Clinique incorporates Pro Vitamin D into select formulas to help bolster skin’s natural environmental stress-defense system and protect skin against daily dehydrators like pollution, blue light, and other environmental aggressors. Using a formula with Pro Vitamin D means you’re aligning with Clinique’s science-driven approach to strong skin resilience.

Here are a few great options:

• Clinique Moisture Surge Broad Spectrum SPF 28 Sheer Hydrator – Cloud-like cream with SPF 28 and includes Pro Vitamin D.
• Clinique Smart Clinical Repair Broad Spectrum SPF 30 Wrinkle Correcting Cream – Anti-aging moisturizer listing Pro Vitamin D in key ingredients.

Treat a Pro Vitamin D-infused product just like you would any high-performance moisturizer or SPF step: cleanse your skin, apply your targeted treatments such as serum or eye treatment, then follow with the product containing Pro Vitamin D as your final step of that sequence morning and evening as directed.
Because Pro Vitamin D works to support environmental defense and hydration, using such a formula in the morning is particularly beneficial when your skin faces daily stressors.

Yes, you can. For example, you might use a serum targeting a specific concern such as uneven tone or fine lines and then apply one of the Clinique products above. Since Pro Vitamin D helps support your skin’s protective and hydrating functions, pairing it with your usual treatment steps makes sense. Follow the lightest-to-heaviest rule, applying serum before moisturizer or SPF, and ensure compatibility if you’re using exfoliants, retinoids, or strong actives.

Yes. Both of the Clinique products recommended above are described as allergy tested and safe for sensitive skin. For example, the Moisture Surge Broad Spectrum SPF 28 Sheer Hydrator is labeled dermatologist tested, safe for sensitive skin, and allergy tested.

No. While Pro Vitamin D supports your skin’s defense against environmental stressors and dehydration, it does not replace primary sun-protection measures in the morning such as a broad-spectrum SPF. If your Clinique product includes SPF, like the Clinique Moisture Surge Broad Spectrum SPF 28 Sheer Hydrator or Clinique Smart Clinical Repair Broad Spectrum SPF 30 Wrinkle Correcting Cream, it serves dual purposes of protection and moisture. If you use a formula without SPF, you still need to apply a dedicated sunscreen after.

Because Pro Vitamin D works on your skin’s protective and moisture-retention systems rather than quick surface changes, you can expect gradual improvement in how resilient and hydrated your skin looks and feels. Track your skin’s comfort, plumpness, and ability to resist environmental stress over two to four weeks and beyond.
