Guidelines for Oily, Combination, Dry, and Sensitive-Prone Skin

Oily and combination skin are the product's most direct official target types. If your skin tends to become oily in the afternoon while traveling, or your base makeup looks uneven around the nose or on textured areas of the cheeks, the key is not how many serums you layer at once. Keep use of SKIN1004 Niacinamide 10 Boosting Shot Ampoule within the adjustment-period frequency first.([skin1004.com](https://www.skin1004.com/products/niacinamide-10-boosting-shot-ampoule?utm_source=openai))

For skin prone to dryness, do not equate a high concentration with daily use. The official routine is to cleanse, smooth the skin with toner or a toner pad, apply the ampoule, then finish with a moisturizing product after it absorbs. Following this nighttime order after checking into your hotel is easier to keep consistent than adding extra product just before rushing out for your itinerary.([skin1004.com](https://www.skin1004.com/products/niacinamide-10-boosting-shot-ampoule?utm_source=openai))

For sensitive-prone skin, perform a patch test first. The official guidance also notes that the sensation of hydrolyzed sponge spicules may cause temporary tingling or redness, which generally subsides within 1 to 2 hours. Do not use it when skin is irritated or damaged, and avoid the eye and lip areas.([skin1004.com](https://www.skin1004.com/products/niacinamide-10-boosting-shot-ampoule?utm_source=openai))
