Dull skin doesn’t mean you’re unhealthy. It just means your face needs a bit of help. 

You could be doing everything “right” and still wake up with your skin feeling flat. Whether it’s stress, poor sleep, city air, or too many takeout meals, it all shows on your skin.

Dermatologists don’t mess around with trends. They stick with what works. So if you’re ready to stop wasting time and actually see results, these seven glow-up tips are backed by science, not hype. 

1. Exfoliate the right way for instant glow

When dead cells pile up, skin renewal slows down, and light cannot reach fresh layers. 

Rough scrubs may feel satisfying, but they can cause tiny tears and inflamed patches that make dullness worse. 

Chemical exfoliants break the bonds between cells, so you do not need to scrub. 

There are two main types you should know:

Alpha hydroxy acids or AHAs, like glycolic acid or lactic acid, work on the top layer to remove surface buildup. They suit dry or combination skin that needs a gentle polish.

Beta hydroxy acids or BHAs, like salicylic acid, penetrate pores to clear oil and debris. They fit oily or acne-prone skin that needs deeper cleaning. 

If you are not sure which one to pick, start with a low concentration AHA and switch to BHA later if breakouts or extra oil are your main concern. 

Avoid exfoliating on broken or inflamed skin, skip acids after shaving, and never layer them with retinoids on the same day. 

Always follow with a moisturiser and then a broad-spectrum sunscreen.

How to start

• Use an exfoliant once per week at 5 to 10 percent concentration
• Apply on clean, dry skin and rinse after one minute
• If tingling or redness appears, pause for one week
• When your skin adjusts, add a second session, up to three per week

2. Use vitamin C every morning

Vitamin C does three things at once: it fades dark marks, boosts collagen production, and protects skin from pollution. It also helps your sunscreen absorb UV rays more effectively, reducing long-term damage. 

Look for a serum that lists L-ascorbic acid first at 10 to 20 percent strength. Anything above 20 percent usually leads to irritation without extra benefits.

Store your bottle away from heat and light. When vitamin C turns brown, it has oxidised and lost its power. 

A mild tingle is normal at first, but a strong burn means it is too strong. If that happens, switch to a lower concentration or a derivative like magnesium ascorbyl phosphate.

How to apply

• Cleanse and pat your skin fully dry
• Place two to three drops on your fingertips
• Press the serum into face and neck areas
• Let it absorb for one to two minutes
• Follow with moisturiser and broad-spectrum SPF

Use daily for at least four weeks to notice fewer spots and a more even tone.

3. Hydrating masks give a quick fix for tired skin

Even healthy skin can look dull when it lacks water. 

A hydrating mask adds moisture to the top layer and plumps fine lines in minutes. Sheet masks soaked in hyaluronic acid pull water back into the surface. 

Apply before makeup to give your skin a dewy finish. Gel or overnight masks with glycerin or aloe vera lock in hydration while you sleep, so you wake up with a smoother feel.

Use masks one to two times per week unless your skin is extremely dry. Think of them as boosters, not daily treatments. 

How to use masks

• Sheet mask: unfold and place on clean skin, leave for at most half an hour, peel off and pat in excess serum
• Gel mask: apply a thin layer before bed, leave on overnight, rinse or gently wipe off in the morning

4. Niacinamide at night keeps skin calm and clear

Niacinamide, also called vitamin B3, works from deep within your barrier to reduce redness, tighten pores, and improve texture without irritation. Unlike acids, it is non-abrasive and mixes well with other actives. 

When you use niacinamide consistently, most people see smoother tone and less blotchiness in three to six weeks. It does not deliver instant glow, but it builds a more even canvas over time.

For best results, use a serum with 5 to 10 percent niacinamide. Higher percentages do not add more benefits and may irritate sensitive skin. 

After cleansing, apply niacinamide before your moisturiser. Nighttime is ideal, especially if you use vitamin C in the morning.

How to apply

• Cleanse and pat dry
• Dispense two to three drops of niacinamide serum
• Press into face and neck
• Wait one to two minutes before applying moisturizer

5. Sunscreen matters even indoors

UVA rays pass through windows, clouds, and car windshields. They break down collagen and cause uneven tone long before you see sunburn. 

A broad-spectrum SPF 30 or higher protects against both UVA and UVB. Apply it every morning, even when you plan to stay indoors, and reapply every two hours if you go outside or sweat.

Foundation or tinted moisturiser with SPF is not enough protection. To reach the labelled SPF, you would need about a teaspoon of product, most people use far less. 

Use makeup for coverage and your dedicated sunscreen for defence.

How to apply

• After moisturiser, spread a nickel-sized amount over face and neck
• Reapply every two hours if exposed to sun or heat

6. Cleanse properly without stripping your face

A strong barrier holds in moisture and keeps irritants out. A weak barrier leads to dryness and dullness, but under-cleansing leaves behind sweat, oil, and pollution that clog pores. A two-step cleanse at night clears everything without overstripping:

First, use an oil-based balm or micellar water to melt makeup and sunscreen. 

Then follow with a mild cream or gel cleanser that rinses clean without leaving tightness. In the morning, if you wore only light products or just sweat, a splash of water or a gentle gel cleanser is enough.

Look for cleansers free of sulfates, with a pH between 5 and 6, and supportive ingredients like ceramides or glycerin. 

How to cleanse

• Stage one: massage oil balm or micellar water over dry skin, then rinse or wipe off
• Stage two: apply cream or gel cleanser, massage over damp skin, rinse thoroughly

Your face should feel soft, not tight, after each step.

7. Try dermatologist-approved treatments

If you want faster or more dramatic results, a board-certified dermatologist can offer in-office options that go beyond what you can do at home. 

Rejuran uses polynucleotide derived from salmon DNA to support repair, boost hydration, and smooth fine lines. It typically involves three sessions spaced four weeks apart, with minimal downtime and results that build over three months. 

A chemical peel with glycolic acid or trichloroacetic acid resurfaces uneven tone and stimulates new collagen; you can expect light peeling for three to five days. 

Microneedling creates microchannels that trigger collagen production and improve serum absorption; most people complete three to six sessions a month apart, with redness that subsides in one to two days. 

LED red light therapy uses specific wavelengths to reduce inflammation and support collagen in eight to ten sessions, all with little or no downtime. Retinoids such as tretinoin or adapalene encourage faster cell turnover than over-the-counter retinol but require a slow buildup under medical guidance to minimise irritation. 

Each of these treatments carries its own cost, timeline, and side-effect profile, and a pro can tailor a plan that fits your skin type and goals.

How to glow inside and out

True radiance comes from building and sticking with a simple routine. 

Start with gentle cleansing to protect your barrier, exfoliate once or twice a week to lift away dead cells without causing damage, apply vitamin C each morning to fade spots and boost protection, and use niacinamide every night to calm and refine. Hydrate with a mask once or twice a week and never skip broad-spectrum SPF 30 or higher to seal in your work. 

When your skin is ready, layer in dermatologist-approved options such as Rejuran, chemical skin peels, microneedling or red light therapy, and use at-home sheet masks for a gentle pick-me-up.

Results do not happen overnight but they do happen. 

Give each active ingredient at least four weeks to show its effect, track progress with a weekly photo in natural light, and trust the process. This steady approach will transform dull skin into a noticeably brighter, smoother and healthier complexion you can maintain long term.
