What Can You Do About Dull, Rough Skin?
Understand the Difference Between Retinol, AHA, BHA,
and Renewal-Focused Skincare

When skin looks dull, feels rough, or makeup tends to cling before application, many people start searching for “renewal skincare.” However, different ingredients follow different skincare logic and offer different usage experiences. Choosing the right rhythm is what helps prevent the skin from becoming more unstable through over-care.

Renewal skincare is not about using the strongest formula.
It is about finding the right rhythm for your skin.

Skin is affected every day by age, lifestyle, dryness, sun exposure, and environmental changes. When dead skin cells build up on the surface, or when your skincare rhythm becomes unbalanced, the skin may appear dull, rough, uneven, or less smooth under makeup.

At this point, many people think of renewal-focused ingredients such as retinol, fruit acids, and salicylic acid. But each ingredient is suitable for different skin conditions and usage methods. Instead of blindly pursuing strength, it is better to first understand what your skin truly needs.

Retinoic acid belongs to the medication / prescription-use range.
It is not recommended to use it as a daily skincare product on your own.

Retinoic acid is not a general skincare ingredient. It belongs to a usage range that requires professional evaluation. If your skin has obvious discomfort, acne, clogged pores, or other skin concerns, it is recommended to consult a professional physician first instead of mixing high-irritation skincare products on your own.

Retinol is a common daily renewal ingredient
found in skincare products.

Retinol is commonly found in renewal-focused skincare products and is suitable for those who want to address dullness, roughness, and early aging-related skin feel. Compared with retinoic acid, retinol is more often designed for daily skincare use, but tolerance still needs to be built according to skin condition.

When first trying retinol skincare, it is recommended to start with a low frequency and small amount, while pairing it with hydration and sunscreen. If obvious dryness, tightness, or discomfort occurs, pause use or reduce the frequency first.

AHA focuses more on surface keratin care,
suitable for those concerned about roughness and dullness.

AHA is commonly seen in keratin-care skincare products and is suitable for those who want to address surface roughness, dullness, and the feeling of dead skin buildup. After use, the skin may feel brighter and smoother, but some skin types may also experience dryness, tightness, or tingling.

If your skin is naturally dry, sensitive, or unstable during seasonal changes, it is recommended to lower the frequency first and avoid layering too many renewal-focused ingredients at the same time.

BHA focuses more on oil and keratin care.
When using it, pay closer attention to concentration and labeling.

BHA is commonly found in skincare products related to oil control, pores, and blemish-prone concerns. It leans toward refreshing keratin care. If your skin is dry or sensitive, pay special attention to the product label, usage frequency, and hydration pairing.

Renewal is not just about turnover.
It is about helping skin return to a refined, radiant skincare rhythm.

If you are looking for an essence lotion suitable for daily use that balances renewal, repair-supporting care, and a stable skin feel, you can start with Daily Secret NO.01 and gradually build your own skin glow rhythm.
