A hydrating, water-based primer that’s specially designed for long-wear foundations.
What it does:
Lock-It Hydrating Primer is an ultra-hydrating, water-based formula that preps your skin for perfect long-wear foundation application and comfortable all-day wear. Formulated with a lightweight, milky texture that feels weightless on the skin, it’s infused with nourishing ingredients, including vitamin B5, aloe vera, jojoba, and shea.
This primer features skin-smoothing oxygen-boosters to help long-wear foundations glide evenly onto skin for a poreless, soft finish. Fragrance free, colorless, and supremely hydrating, it’s ideal for dry, sensitive skin types.
What it is formulated WITHOUT:
- Parabens
- Sulfates
- Phthalates
What else you need to know:
You can use Lock-It Hydrating Primer with any long-wear formula, but its perfect match is Kat Von D’s Lock-It Foundation (sold separately). Pair them together for ultimate comfort and unstoppable 24-hour wear.
Artistry tip: if you want a more lightweight, dewy finish, mix one pump of Lock-It Hydrating Primer with one pump of Lock-It Foundation on the back of your hand. Swirl to blend the two formulas together and apply as normal. Use a higher primer-to-foundation ratio to achieve more sheer and lightweight coverage. This technique is perfect for dry skin, and it’s the ultimate solution to achieve a dewy, flawless finish with your long-wear, full-coverage foundation.
