"Healthy skin comes from the right routine, not more products."
Most skin problems — acne, oiliness, dryness, sensitivity, dullness, and pigmentation — are caused by irritation, barrier damage, and incorrect daily habits over time, not “dirty skin.”
This guide helps you understand your skin, choose products correctly, and avoid common skincare mistakes. At CORPHARM, we follow a science-led, gentle approach that supports the skin barrier and improves results with consistent daily care.
Use this guide to find clear answers, build a routine that suits your skin, and make smarter skincare decisions — step by step.
FACE WASH & CLEANSING
Is it necessary to use a face wash even if I don’t go outside?
Yes, in most cases you should still use a face wash even if you stay indoors. Your skin continues to produce oil, sweat, and dead skin cells, and it also collects dust, bacteria, and residue from skincare products. Gentle cleansing helps keep pores clear and skin healthy.
Can a face cleanser really help with dark spots and dull skin?
A face cleanser alone cannot remove dark spots, but the right cleanser supports brighter skin by keeping pores clean and preparing the skin to absorb treatment products. Gentle cleansing also prevents irritation, which can otherwise make pigmentation look worse.
Why does my skin feel tight and dry after washing my face?
If your skin feels tight and dry after washing, your cleanser is likely too harsh or stripping your natural protective oils. This tight feeling is a sign of skin barrier disruption, not cleanliness. Over time, this leads to more dryness, sensitivity, and irritation.
SKIN TYPE & ROUTINE
How can I accurately identify my skin type at home?
Wash your face with a gentle cleanser, apply no products, and observe your skin after 2–3 hours. If it feels tight, it’s dry; if it’s shiny all over, it’s oily; if only the T-zone is shiny, it’s combination; if it feels comfortable, it’s normal.
What is the best daily skincare routine for oily skin?
The best routine for oily skin focuses on gentle cleansing, lightweight hydration, and sun protection. Use a gentle cleanser twice daily and a lightweight moisturizer. Avoid harsh products, as stripping the skin usually increases oil production over time.
What is the best daily skincare routine for acne-prone skin?
A routine for acne-prone skin should be simple and consistent. Cleanse twice daily with a gentle cleanser, use a non-comedogenic moisturizer, and apply sunscreen. Avoid over-cleansing and harsh scrubs, which often worsen acne by irritating the skin.
