How to Control Excess Sebum Production on Oily Skin

If your face is shiny by midday, your makeup slides off, and your pores look large and congested, you are dealing with excess sebum. Oily skin is one of the most common skin types, especially in India's warm, humid climate, and while some oil is healthy and necessary, too much leads to shine, clogged pores, and breakouts. The key thing to understand is that you cannot and should not try to strip away all your oil, because that backfires badly. Instead, the goal is to balance and control it. This guide covers what causes excess sebum and how to control it properly. If you want a brand with clean, effective actives for oily skin, Biom:logy, India's first INCI Beauty-rated skincare brand, is a great place to start.

What is sebum and why does the skin produce it?

Sebum is the natural oil your skin produces, made by tiny glands in your pores called sebaceous glands. It is not the enemy. In the right amount, sebum keeps your skin moisturised, protected, and healthy, and it forms part of the barrier that keeps moisture in and irritants out. The problem only starts when the glands produce too much of it.

When there is excess sebum, it mixes with dead skin cells and clogs pores, leading to shine, blackheads, closed comedones, and breakouts. So controlling oily skin is not about eliminating sebum; it is about bringing overactive glands back into balance while keeping the skin healthy.

What causes excess sebum production?

Several things drive the skin to produce too much oil:

• Genetics, since oily skin often runs in families and is partly just your natural skin type
• Hormones, which strongly influence oil production. This is why oiliness often peaks in the teens and can flare with hormonal changes.
• Climate and humidity, since heat and humidity, common in India, ramp up oil production. Overwashing and harsh products, which strip the skin and trigger it to produce even more oil to compensate
• Skipping moisturiser, which does the same thing, since dehydrated skin overproduces oil to protect itself
• Using the wrong products, especially heavy or pore-clogging ones that unbalance the skin

Notice how many of these are things people do to their skin trying to fix oiliness. Overwashing, skipping moisturiser, and stripping the skin all make oil worse, not better. This is the most important thing to get right.

The best way to control sebum

The most effective way to control excess sebum is to use ingredients that regulate oil production at the source while keeping pores clear, without stripping or damaging the skin. Niacinamide is the star ingredient for this, as it genuinely reduces how much oil the glands produce, and salicylic acid keeps the pores clear of the oil and debris that cause breakouts.

Biom:logy's Anti Acne Serum, with 7% niacinamide, 2% salicylic acid, and ceramides, is ideal for controlling oily skin. The niacinamide regulates oil production so your skin makes less of it over time; the salicylic acid clears pores to prevent congestion and breakouts, and the ceramides keep the barrier intact so the skin does not get stripped into overproducing. This controls oil at the root rather than just mopping up shine. Rated 18.5 out of 20 on INCI Beauty. SLS-free, paraben-free, and dermatologist-tested. Use it morning and night.

Hydration is not the enemy of oily skin.

This is the mistake almost everyone with oily skin makes. They avoid moisturiser and hydration, thinking it will add to the oiliness. In fact, the opposite happens. When oily skin is dehydrated, it panics and produces even more oil to compensate for the missing moisture. Proper hydration actually tells the glands to calm down.

The trick is to hydrate with lightweight, non-greasy products rather than heavy creams. Biom: logy's Healthy Glow Serum works well for oily skin because it provides hydration and barrier support in a light formula that does not feel heavy or greasy. Keeping oily skin properly hydrated is one of the most effective and most overlooked ways to bring oil production back into balance. Do not skip hydration just because your skin is oily.

Oil control and even tone together

Oily skin often comes with other concerns like enlarged pores, dark marks from past breakouts, and uneven tone. Since niacinamide helps with oil control, pore appearance, and brightening all at once, it is a particularly valuable ingredient for oily skin that also wants a more even, refined complexion.

Biom: logy's Brightening face serum, with niacinamide, alpha arbutin, and vitamin C, supports oil control through the niacinamide while also fading dark spots and evening out tone. For oily skin dealing with marks and unevenness alongside the shine, using this in the morning addresses several concerns at once, giving you skin that is balanced, clearer, and more even in tone.

Oily skin and ageing

There is one small silver lining to oily skin: it often ages a little more slowly, since the extra oil keeps the skin lubricated. But oily skin still needs anti-ageing care, and the challenge is getting it without heavy, pore-clogging products. Retinol is ideal here, as it not only supports anti-ageing but also helps oily skin by keeping pores clear and refining texture.

Biom:logy's Anti-Ageing Serum, with 0.3% HD Retinol, 2% Ceramide, Bamboo Water, and Stevioside, suits oily, ageing skin because retinol renews the skin and keeps pores clear, while the light formula avoids heaviness. Rated 19.1 out of 20 on INCI Beauty. Night use only. Used a few nights a week, it delivers anti-ageing benefits and helps with congestion at the same time, which is a great combination for oily skin.

How to control oily skin naturally: daily habits

• Cleanse gently twice a day, no more, since over-washing triggers more oil. Use a mild, SLS-free cleanser.
• Never skip moisturising; use a lightweight, non-greasy formula to keep skin hydrated and calm the oil glands.
• Use niacinamide daily to regulate oil production at the source over time
• Keep pores clear with salicylic acid, a few times a week or daily depending on your skin
• Choose non-comedogenic, oil-free products, so nothing clogs your pores or adds grease
• Do not over-strip your skin, since harsh toners and scrubs backfire and increase oil
• Use a light sunscreen every morning, choosing a matte or gel formula made for oily skin
• Blot, do not scrub, during the day, using blotting paper to remove shine gently instead of washing again. The single most important thing to understand about oily skin: stripping it makes it worse. Every time you over-wash, skip moisturiser, or use harsh products to dry out the oil, your skin responds by producing even more. The way to control sebum is to balance the skin gently, regulate oil with niacinamide, keep it hydrated, and never strip it. Balance, not war.

Frequently asked questions

How can I control sebum production on my face naturally?
Control sebum naturally by cleansing twice a day gently, never skipping a lightweight moisturiser, using niacinamide to regulate oil at the source, and keeping pores clear with salicylic acid. Avoid over-washing and harsh products, since stripping the skin makes it produce more oil. Choose non-comedogenic products and a light sunscreen. Balance and consistency work far better than trying to dry the skin out.

What causes excess sebum production?
Excess sebum is caused by genetics, hormones, heat and humidity, and often by things people do to their skin, like over-washing, skipping moisturiser, and using harsh or heavy products. Many of these strip the skin, which triggers even more oil in response. Understanding this is key, because the fix is to balance the skin gently rather than aggressively drying it out.

Does niacinamide help control oil?
Yes, niacinamide is one of the best ingredients for controlling oil. It genuinely reduces how much sebum the glands produce over time, rather than just mopping up surface shine. It also refines pores, calms inflammation, and strengthens the barrier, all of which help oily skin. Used consistently at an effective level, niacinamide brings oil production into balance while keeping the skin healthy.

How often should oily skin use a serum?
Most oil-controlling serums with niacinamide and salicylic acid can be used once or twice daily, morning and night, and are gentle enough for it. If you are new to salicylic acid, start once a day and build up. A retinol serum, if used, should start a few nights a week. Always follow with a light moisturiser and daily sunscreen for balanced results.
